Add peer and key handling for listen and connected sockets as
well as the setsockopt() key interface.

When TCP-AO is activated on a TCP socket a tcp_ao control block
is allocated and attached to the tcpcb.  An arbitrary number of
peer addresses and keys can be added.  On accepting of a new
incoming connection only the peers keys are copied to the new
socket.  On outbound connecting sockets only the keys for the
peer address will be kept.

Some parts are not fully implemented yet and other may change
again.

Bring over the initial, CPU-only UART support for the AR933x SoC.

This implements the kernel glue needed (getc, putc, rxready).

This isn't a 16550 UART, even if the datasheet overview claims so.

The Linux ar933x support was used as a reference, however the uart code
is a reimplementation.

Attentive viewers will note that the uart code is based off of the ns8250
code and the UART bus code is a stubbed-out version of this.  I'll be
replacing it with non-stubbed versions soon, making this a fully featured
driver.

Tested:

* AP121 reference board (AR933x), booting through the mountroot> prompt;
  then doing some basic interactive tests in ddb.

Welcome clang as the default compiler on ARM.

Change the default compiler for little-endian ARM to clang to allow for more
testing before 10.0 is released. As LLVM and clang currnetly lack support
for big-endian ARM leave gcc as the default there.

This will also allow us to investigate moving to use the hard floating-point
version of the ARM EABI on SoCs that include the Vector Floating Point unit.
A version of this is included in all ARMv6 and ARMv7 SoCs we currently, and
are likely to support.

Both the current ABI and the new EABI are supported by clang and it will be
built correctly depending on which is selected by the user.

Add project branch to work on improving CAM performance and scalability.
Such goals are planned within this project:

1) Remove request allocation queue on the SIM level.  This supposed to
simplify the code and reduce relations between device and transport/SIM.
It will reduce effectiveness of bioq_disksort() in situations when several
devices share single SIM, which queue is unable to fit all request allocated
same time. But hopefully that is not a problem since SATA devices in most
cases are not sharing queues, while SAS HBAs usually have large queues.
Those people who need better scheduling can use to use more functional
gsched.

2) Remove multilevel queue freezing mechanism.  It was created to allow
periph drivers to allocate more CCBs then device/SIM can handle in cases
of error recovery.  After 1) succeed, it should not be a big problem to
create another less complicated mechanism to handle overcommit.

3) Remove per-SIM queue of allocated CCBs.  That will additionally reduce
relations between device and SIM, while UMA should be able to handle memory
no less effectively now.

4) Try to split device locking into separate mutex(es).  It should reduce
SIM lock contention, that is now the main limiting factor for CAM SMP
scalability.  Hopefully after 1), 2) and 3) relations between device and
SIM will be minimal, making this goal reachable.

5) Hardware of some controllers, such as mps(4), allows to have several
request/response queues. Using them should improve SMP scalability.
Additional locking changes are required to do it, but hopefully it will
be easier after 4).

6) Success of 4) should also make reachable other following goals, such
as CAM-level multipathing, etc.

MFC r248256:

- Fix two possible overflows when testing if ELF program headers are on
  the first page:
  1. Cast uint16_t operands in a multiplication to unsigned int because
     otherwise the implicit promotion to int results in a signed
     multiplication that can overflow and the behaviour on integer
     overflow is undefined.
  2. Replace (offset + size > PAGE_SIZE) with (size > PAGE_SIZE - offset)
     because the sum may overflow.
- Use the same tests to see if the path to the interpreter is on the first
  page. There's no overflow here because size is already limited by
  MAXPATHLEN, but the compiler optimises the new tests better. Also fix an
  off-by-one error.
- Simplify tests to see if an ELF note program header is on the first page.
  This also fixes an off-by-one error.

Adds the ability to enable / disable sorting of BIO requests queued within
CAM. This can significantly improve performance particularly for SSDs
which don't suffer from seek latencies.

The sysctl / tunable kern.cam.sort_io_queues provides the systems default
setting where:-
0 = queued BIOs are NOT sorted
1 = queued BIOs are sorted (default)

Each device gets its own sysctl kern.cam.<type>.<id>.sort_io_queue
Valid values are:-
-1 = use system default (default)
0 = queued BIOs are NOT sorted
1 = queued BIOs are sorted

Note: Additional patch will look to add automatic use of none sorted queues
for none rotating media e.g. SSD's

to the OpenWRT project and Linux kernel from
Gabor Juhos <juhosg@openwrt.org>.

The original ticket for this code is https://dev.openwrt.org/ticket/12031 .

I've contacted Gabor and asked for his permission to also licence the patch
in question (which covers this code) to BSD lience and he's agreed.
Hence why I'm including it here in FreeBSD.

MFC 246876:

Add barrier write capability to the VFS buffer interface. A barrier
write is a disk write request that tells the disk that the buffer
being written must be committed to the media along with any writes
that preceeded it before any future blocks may be written to the drive.

Barrier writes are provided by adding the functions bbarrierwrite
(bwrite with barrier) and babarrierwrite (bawrite with barrier).

Following a bbarrierwrite the client knows that the requested buffer
is on the media. It does not ensure that buffers written before that
buffer are on the media. It only ensure that buffers written before
that buffer will get to the media before any buffers written after
that buffer. A flush command must be sent to the disk to ensure that
all earlier written buffers are on the media.

MFC 246877:

The UFS2 filesystem allocates new blocks of inodes as they are needed.
When a cylinder group runs short of inodes, a new block for inodes is
allocated, zero'ed, and written to the disk. The zero'ed inodes must
be on the disk before the cylinder group can be updated to claim them.
If the cylinder group claiming the new inodes were written before the
zero'ed block of inodes, the system could crash with the filesystem in
an unrecoverable state.

Rather than adding a soft updates dependency to ensure that the new
inode block is written before it is claimed by the cylinder group
map, we just do a barrier write of the zero'ed inode block to ensure
that it will get written before the updated cylinder group map can
be written. This change should only slow down bulk loading of newly
created filesystems since that is the primary time that new inode
blocks need to be created.

MFC 247387:

An inode block must not be blockingly read while cg block is owned.
The order is inode buffer lock -> snaplk -> cg buffer lock, reversing
the order causes deadlocks.

Inode block must not be written while cg block buffer is owned. The
FFS copy on write needs to allocate a block to copy the content of the
inode block, and the cylinder group selected for the allocation might
be the same as the owned cg block.  The reserved block detection code
in the ffs_copyonwrite() and ffs_bp_snapblk() is unable to detect the
situation, because the locked cg buffer is not exposed to it.

In order to maintain the dependency between initialized inode block
and the cg_initediblk pointer, look up the inode buffer in
non-blocking mode. If succeeded, brelse cg block, initialize the inode
block and write it.  After the write is finished, reread cg block and
update the cg_initediblk.

If inode block is already locked by another thread, let the another
thread initialize it.  If another thread raced with us after we
started writing inode block, the situation is detected by an update of
cg_initediblk.  Note that double-initialization of the inode block is
harmless, the block cannot be used until cg_initediblk is incremented.

When building universe ensure the required worlds are finished before
starting the kernels. Before this the kernels would be built as part of the
last architecture universe target. There can cause problems when this world
finishes before the other worlds as the host compiler may be picked up
rather than the target compiler.

The solution is to add a target to build the universe kernels that depends
on all the world targets finishing. As we may not be building a world only
depend on it when MAKE_JUST_KERNELS is undefined.

Accommodate uart devices with large FIFOs (or DMA buffers which amount
to the same thing) by allocating the uart(4) rx buffer based on the
device's rxfifosz rather than using a hard-coded size of 384 bytes.

The  historical 384 byte size is 3 times the largest hard-coded fifo
size in the tree, so use that ratio as a guide and allocate the buffer
as three times rxfifosz, but never smaller than the historical size.

Enable hardware flow control and high speed bulk data transfer in at91 uarts.

Changes to make rtc/cts flow control work...

This does not turn on the builtin hardware flow control on the SoC's usart
device, because that doesn't work on uart1 due to a chip erratum (they
forgot to wire up pin PA21 to RTS0 internally).  Instead it uses the
hardware flow control logic where the tty layer calls the driver to assert
and de-assert the flow control lines as needed.  This prevents overruns at
the tty layer (app doesn't read fast enough), but does nothing for overruns
at the driver layer (interrupts not serviced fast enough).

To work around the wiring problem with RTS0, the driver reassigns that pin
as a GPIO and controls it manually.  It only does so if given permission via
hint.uart.1.use_rts0_workaround=1, to prevent accidentally driving the pin
if uart1 is used without flow control (because something not related to
serial IO could be wired to that pin).

In addition to the RTS0 workaround, driver changes were needed in the area
of reading the current set of DCE signals.  A priming read is now done at
attach() time, and the interrupt routine now sets SER_INT_SIGCHG when any
of the DCE signals change.  Without these changes, nothing could ever be
transmitted, because the tty layer thought CTS was de-asserted (when in fact
we had just never read the status register, and the hwsig variable was
init'd to CTS de-asserted).

Changes to support bulk high-speed (230kbps and higher) data reception...

Allow the receive fifo size to be tuned with hint.uart.<dev>.fifo_bytes.
For high speed receive, a fifo size of 1024 works well.  The default is
still 128 bytes if no hint is provided.  Using a value larger than 384
requires a change in dev/uart/uart_core.c to size the intermediate
buffer as MAX(384, 3*sc->sc_rxfifosize).

Recalculate the receive timeout whenever the baud rate changes.  At low
baud rates (19.2kbps and below) the timeout is the number of bits in 2
characters.  At higher speed it's calculated to be 500 microseconds
worth of bits.  The idea is to compromise between being responsive in
interactive situations and not timing out prematurely during a brief
pause in bulk data flow.  The old fixed timeout of 1.5 characters was
just 32 microseconds at 460kbps.

At interrupt time, check for receiver holding register overrun status
and set the corresponding status bit in the return value.

When handling a buffer overrun, get a single buffer emptied and handed
back to the hardware as quickly as possible, then deal with the second
buffer.  This at least minimizes data loss compared to the old logic
that fully processed both buffers before restarting the hardware.

Rewrite the logic for handling buffers after a receive timeout.  The
original author speculated in a comment that there may be a race with
high speed data.  There was, although it was rare.  The code now handles
all three possible scenarios on receive timeout: two empty buffers, one
empty and one partial buffer, or one full and one partial buffer.

Fix low-level uart drivers that set their fifo sizes in the softc too late.

uart(4) allocates send and receiver buffers in attach() before it calls
the low-level driver's attach routine.  Many low-level drivers set the
fifo sizes in their attach routine, which is too late.  Other drivers set
them in the probe() routine, so that they're available when uart(4)
allocates buffers.  This fixes the ones that were setting the values too
late by moving the code to probe().

  1. Cast uint16_t operands in a multiplication to unsigned int because
     otherwise the implicit promotion to int results in a signed

     overflow is undefined.
  2. Replace (offset + size > PAGE_SIZE) with (size > PAGE_SIZE - offset)
     because the sum may overflow.
- Use the same tests to see if the path to the interpreter is on the first
  page. There's no overflow here because size is already limited by
  MAXPATHLEN, but the compiler optimises the new tests better. Also fix an
  off-by-one error.

  This also fixes an off-by-one error.

Dtrace: enablings on defunct providers prevent providers from unregistering

Merge change from illumos:

1368 enablings on defunct providers prevent providers from unregistering

We try to address some underlying differences between the Solaris
and FreeBSD implementations: dtrace_attach() / dtrace_detach() are
currently unimplemented in FreeBSD but the new code from illumos
makes use of taskq so some adaptations were made to dtrace_open()
and dtrace_close() to handle them appropriately.

Only unmap the RX mbuf DMA map if there's a buffer here.

The normal RX path (ath_rx_pkt()) will sync and unmap the
buffer before passing it up the stack.  We only need to do this
if we're flushing the FIFO during reset/shutdown.

Use ATH_MAX_SCATTER rather than ATH_TXDESC.

ATH_MAX_SCATTER is used to size the ath_buf DMA segment array.
We thus should use it when checking sizes of things.

wordexp(): Remove wrong IFS usage.

Words in shell script are separated by spaces or tabs independent of the
value of IFS. The value of IFS is only relevant for the result of
substitutions. Therefore, there should be a space between 'wordexp' and the
words to be expanded, not an IFS character.

Paranoia might dictate that the shell ignore IFS from the environment (even
though our sh currently uses it), so do not depend on it in the new test
case.

Ensure that we only call the busdma unmap/flush routines once, when
the buffer is being freed.

* When buffers are cloned, the original mapping isn't copied but it
  wasn't freeing the mapping until later.  To be safe, free the
  mapping when the buffer is cloned.

* ath_freebuf() now no longer calls the busdma sync/unmap routines.

* ath_tx_freebuf() now calls sync/unmap.

* Call sync first, before calling unmap.

Tested:

* AR5416, STA mode

Follow up to r247960 and rr247960 by also amending ctfmerge.  For the
only other case where STT_FILE symbols are used, in symit_next() in
cddl/contrib/opensolaris/tools/ctf/cvt/input.c, save the basename of the
symbol, instead of the full pathname.

Fix return type of extattr_set_* and fix rmextattr(8) utility.

extattr_set_{fd,file,link} is logically a write(2)-like operation and
should return ssize_t, just like extattr_get_*.  Also, the user-space
utility was using an int for the return value of extattr_get_* and
extattr_list_*, both of which return an ssize_t.
