Sync libarchive with 9-CURRENT:

MFC on lib/libarchive:
196961,200351,201077,201079-201097,201099-201112,201155-201157,
201159-201163,201165,201167-201171,201246-201250,201253,202868-202869,
202871-202873,203952,208027,208169,208184,208263,208291,210825,213573,
214822,214867,214905,216258,221472,224152

MFC 196961 (kientzle):
Update tests to match r195873, which corrected how hardlinked files
on iso9660 images were returned.  While I'm poking around, update
some comments around this area to try to clarify what's going on and
what still remains to be improved.

MFC 200351 (kientzle):
Merge two cpio fixes from libarchive.googlecode.com:
 1) Avoid an infinite loop in the header resync for certain malformed
    archives.
 2) Don't try to match hardlinks if the nlinks count is < 2.   This
    reduces the likelihood of a false hardlink match due to ino truncation.

MFC 201077 (kientzle):
Update format manpages for libarchive.

MFC 201079 (kientzle):
Update the hard-coded configuration for libarchive.

MFC 201080 (kientzle):
Remove some unused variables and dead assignments.

MFC 201081 (kientzle):
Remove a dead assignment.

MFC 201082 (kientzle):
Catch certain gzip failures at close time.

MFC 201083 (kientzle):
Compatibility fix for some older systems with non-POSIX getgrnam_r/getpwnam_r
and a minor style fix for the hash function.

MFC 201084 (kientzle):
Sync with googlecode some changes that have no impact on FreeBSD.

MFC 201085 (kientzle):
Compatibility:  I found some more compilers that don't like 'inline' keyword.
Protection:  Discourage people from using this header outside libarchive.

MFC 201086 (kientzle):
Discourage people from using this header outside of libarchive.

MFC 201087 (kientzle):
Enforce this as an internal-only header.

MFC 201088 (kientzle):
Allow more formats to be active at a time; discourage outside use.

MFC 201089 (kientzle):
Portability: terminate abnormally via abort() instead of segfault,
watch the return value from write(), and avoid signed arithmetic on
unsigned values.

MFC 201091 (kientzle):
Remove dead assignment.

MFC 201092 (kientzle):
Discourage outside use of this internal header.

MFC 201093 (kientzle):
Portability:  Set the file descriptor to binary mode on Win32

MFC 201094 (kientzle):
Eliminate an unused assignment.

MFC 201095 (kientzle):
Remove an unused variable and an unnecessary increment.

MFC 201096 (kientzle):
Various portability fixes, plus:
 * New "ino64" field.
 * New UTF8 interfaces for hardlink/symlink updates

MFC 201097 (kientzle):
Portability fixes.

MFC 201099 (kientzle):
Use new ino64 interface.

MFC 201110 (kientzle):
Clarify an example so Linux folks won't keep getting confused by this
point.

MFC 201111 (kientzle):
Remove some dead assignments, fix some declarations.

MFC 201112 (kientzle):
Portability.

MFC 201155 (kientzle):
64-bit ino support and discourage bad use of this header.

MFC 201156 (kientzle):
Various style and portability fixes, including:
 * Enforce option interface can only be used before the archive is opened
 * Correctly handle large skips on platforms with 32-bit off_t
 * Use int64_t instead of off_t

MFC 201157 (kientzle):
Catch decompression failures earlier.  In particular, this gives
immediate feedback if we fail to fork an external decompression program.

MFC 201159 (kientzle):
Various fixes when creating objects on disk:
 * Write xattrs last instead of first (required on platforms that use
   system xattrs for security attributes)
 * Better handling of chdir() failures
 * Don't bother trying to shorten files via seek()/write()
 * Fix build on systems that lack link()/symlink()/mknod()
 * Prefer futimens()/utimensat() when they're present

MFC 201160 (kientzle):
Various style fixes to the 'newc' cpio writer:
 * Warn about truncation of ino
 * Use a macro to hide the somewhat obscure pad-to-multiple-of-4 calculation
 * Eliminate some unused variables

MFC 201161 (kientzle):
Style fixes to tar reader:
  For portability, prefer int64_t to off_t.
  Improve numeric overflow handling when parsing.
  Fix some variable types.
  Eliminate some unused results.

MFC 201162 (kientzle):
Style and portability fixes for pax writer.  Mostly very routine, except for:
 * Use ino64 where appropriate
 * Don't pass atime or nsec to ustar formatter

MFC 201163 (kientzle):
Be a little more skeptical of dev/ino matches when reading cpio files.
This eliminates some false-positives in the hardlink detection logic.

MFC 201165 (kientzle):
Minor style fixes plus a fix for an obscure crash on certain malformed
mtree files.

MFC 201167 (kientzle):
If we're linking against liblzma, allow the decompressor to use up to
1<<30 bytes of memory, which is required for some streams.

Also, try to make the taster more discriminating about raw lzma streams.
The detection here is still really weak, though; please use xz instead
of lzma.

MFC 201168 (kientzle):
Zip write support for libarchive.

The initial implementation was developed by Anselm Strauss as part of
Google Summer of Code 2008, then completed by Joerg Sonnenberger.

MFC 201169 (kientzle):
Clear extraneous error messages.

MFC 201170 (kientzle):
Essentially eliminate problems with false hardlinks in POSIX cpio
archives by generating synthetic ino values and mapping values
from disk into the new values.

MFC 201171 (kientzle):
Rationalize the support for cryptographic hashes.

MFC 201246 (kientzle):
Merge Michihiro NAKAJIMA's significant work on the ISO9660 reader
from googlecode:
 * Support for zisofs compressed entries
 * Support for relocated deep directories
 * Direct calculation of link counts for accurate nlink values
   even on images that lack Rockridge extensions
 * Faster handling of the internal file lists.
 * Better detection of ISO variants

MFC 201247 (kientzle):
A raft of test changes and improvements from the Googlecode repository.
In particular, this includes tests for the new features I've merged
over the last few days.

MFC 201248 (kientzle):
UU decoder.  Now that libarchive can recursively taste input streams,
you can do things like this:  tar xvf archive.tar.gz.uu

MFC 201249 (kientzle):
Libarchive in FreeBSD is now synced up with 2.7.901a from
libarchive.googlecode.com

MFC 201250 (kientzle):
Reserve constants for RPM unwrapper and XAR reader.

MFC 201253 (kientzle):
Remove some test files that are no longer used.

MFC 202868 (kientzle):
Fix a memory leak when a filter fails to initialize.

MFC 202869 (kientzle):
Initialize the allocated 'struct zip'.

MFC 202871 (kientzle):
If we can't stat a file, return the correct ARCHIVE_FAILED (this entry can't
be processed any further) and a suitable error string.
In particular, this improves the error-reporting when cpio -o is
given a nonexistent filename.

MFC 202872 (kientzle):
Use a simpler memory-management strategy for the file objects.
Instead of trying to reference-count them and free them as soon
as they are no longer needed, we now just keep them around and free
them all when we release the archive object.  This fixes a number
of minor memory leaks, especially when reading damaged archives.

MFC 202873 (kientzle):
Don't try to hardlink block or character device nodes that come out
of cpio archives.

MFC 203952 (uqs):
Add missing newline in last line of file.

Uncovered via:	fromcvs vs. svn

MFC 208027 (uqs):
mdoc: move CAVEATS, BUGS and SECURITY CONSIDERATIONS sections to the
bottom of the manpages and order them consistently.

GNU groff doesn't care about the ordering, and doesn't even mention
CAVEATS and SECURITY CONSIDERATIONS as common sections and where to put
them.

Found by:       mdocml lint run

MFC 208169 (kientzle):
Reorganize slightly in preparation for making lzma and bz2 support
conditional.

MFC 208184 (delphij):
Fix build.

MFC 208263 (kientzle):
Retry reads that fail with EINTR.  This fixes a problem
with bsdtar failing on SIGINT.

MFC 208291 (uqs):
mdoc: consistently spell our email addresses <foo@FreeBSD.org>

MFC 210825 (joel):
Fix typo.

MFC 213573 (uqs):
mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

MFC 214822 (kientzle):
Clarify the naming:  Methods that free an object should
be called "free".  Retain the old "finish" names to preserve
source compatibility for now.

MFC 214867 (uqs):
Fix manpage markup.

MFC 214905 (kientzle):
If the Zip reader doesn't see a PK signature block
because there's inter-entry garbage, just scan forward
to find the next one.  This allows us to handle a lot
of Zip archives that have been modified in-place.

Thanks to:	Gleb Kurtsou for sending me a sample archive

MFC 216258 (kientzle):
Don't write data into an empty "file."

In particular, this check avoids a warning when
extracting directory entries from certain GNU tar
archives that store directory contents.

MFC 221472 (obrien):
libarchive is mixing libmd and libcrypto -- correct to use one or the other.
[mixing the two can be quite bad -- they define the same context structures,
 but with differing structure members (and sizes)]

MFC 224152 (mm):
- Update libarchive to 2.8.4
- Add support for extracting xar and rpm archives
- Add libarchive_fe subdir (common code for tar and cpio)
