Add TRIM support 
UNMAP/TRIM support is a frequently-requested feature to help
prevent performance from degrading on SSDs and on various other
SAN-like storage back-ends.  By issuing UNMAP/TRIM commands for
sectors which are no longer allocated the underlying device can
often more efficiently manage itself.

This TRIM implementation is modeled on the `zpool initialize`
feature which writes a pattern to all unallocated space in the
pool.  The new `zpool trim` command uses the same vdev_xlate()
code to calculate what sectors are unallocated, the same per-
vdev TRIM thread model and locking, and the same basic CLI for
a consistent user experience.  The core difference is that
instead of writing a pattern it will issue UNMAP/TRIM commands
for those extents.

The zio pipeline was updated to accommodate this by adding a new
ZIO_TYPE_TRIM type and associated spa taskq.  This new type makes
is straight forward to add the platform specific TRIM/UNMAP calls
to vdev_disk.c and vdev_file.c.  These new ZIO_TYPE_TRIM zios are
handled largely the same way as ZIO_TYPE_READs or ZIO_TYPE_WRITEs.
This makes it possible to largely avoid changing the pipieline,
one exception is that TRIM zio's may exceed the 16M block size
limit since they contain no data.

In addition to the manual `zpool trim` command, a background
automatic TRIM was added and is controlled by the 'autotrim'
property.  It relies on the exact same infrastructure as the
manual TRIM.  However, instead of relying on the extents in a
metaslab's ms_allocatable range tree, a ms_trim tree is kept
per metaslab.  When 'autotrim=on', ranges added back to the
ms_allocatable tree are also added to the ms_free tree.  The
ms_free tree is then periodically consumed by an autotrim
thread which systematically walks a top level vdev's metaslabs.

Since the automatic TRIM will skip ranges it considers too small
there is value in occasionally running a full `zpool trim`.  This
may occur when the freed blocks are small and not enough time
was allowed to aggregate them.  An automatic TRIM and a manual
`zpool trim` may be run concurrently, in which case the automatic
TRIM will yield to the manual TRIM.

# Some test cases are known to fail in ways which are not harmful or dangerous.

# issue on the GitHub issue tracker for each test case failure.
#
known_reason = 'Known issue'
#
# Some tests require that a test user be able to execute the zfs utilities.
# This may not be possible when testing in-tree due to the default permissions
# on the user's home directory. When testing this can be resolved by granting
# group read access.

# chmod 0750 $HOME
#
exec_reason = 'Test user execute permissions required for utilities'
#
# Some tests require that the DISKS provided can be partitioned. This is
# normally not an issue because loop back devices are used for DISKS and they
# can be partition. There is one notable exception, the CentOS 6.x kernel is
# old enough that it does not support partitioning loop back devices.
#
disk_reason = 'Partitionable DISKS required'
#
# Some tests require a minimum python version of 3.5 and will be skipped when

#
# Some rewind tests can fail since nothing guarantees that old MOS blocks
# are not overwritten. Snapshots protect datasets and data files but not
# the MOS. Reasonable efforts are made in the test case to increase the
# odds that some txgs will have their MOS data left untouched, but it is
# never a sure thing.
#
rewind_reason = 'Arbitrary pool rewind is not guaranteed'
