  Port of ZoL commit:
  0091d66f4e Correct lock ASSERTs in vdev_label_read/write
  At a minimum, this fixes a blown assert during an MMP test run when running on
  a DEBUG build.

https://www.illumos.org/issues/11770
  Port a few additional MMP fixes from ZoL that came in after our
  initial MMP port.
  4ca457b065 ZTS: Fix mmp_interval failure
  ca95f70dff zpool import progress kstat
  (only minimal changes from above can be pulled in right now)
  060f0226e6 MMP interval and fail_intervals in uberblock

Note from the committer (me).
I do not have any use for this feature and I have not tested it.  I only
did smoke testing with multihost=off.
Please be aware.
I merged the code only to make future merges easier.

Since r354804 libzpool depends on libzfs for get_system_hostid symbol.
Except for zstreamdump, all binaries linked with libzpool were already
linked with libzfs.  So, zstreamdump is the only fall-out.
