Bring over illumos ZFS FMA logic -- phase 1 This first phase brings over the ZFS SLM module, zfs_mod.c, to handle auto operations in response to disk events. Disk event monitoring is provided from libudev and generates the expected payload schema for zfs_mod. This work leverages the recently added devid and phys_path strings in the vdev label. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Don Brady <don.brady@intel.com> Signed-off-by: Tony Hutter <hutter2@llnl.gov> Closes #4673

zed: Fix config_sync autoexpand flood Users were seeing floods of `config_sync` events when autoexpand was enabled. This happened because all "disk status change" udev events invoke the autoexpand codepath, which calls zpool_relabel_disk(), which in turn cause another "disk status change" event to happen, in a feedback loop. Note that "disk status change" happens every time a user calls close() on a block device. This commit breaks the feedback loop by only allowing an autoexpand to happen if the disk actually changed size.
