Fix several redundancy test reliability & debuggability issues.

tests/sys/cddl/zfs/include/libtest.kshlib:
	- Add a generic wait_for mechanism that takes a timeout, dt, and a
	  command+args to run until it returns true.
	- Add an is_pool_state <pool> <state> command.

tests/sys/cddl/zfs/tests/redundancy/redundancy.kshlib:
	- cleanup: Always log the verbose status of the pool.  This is
	  cleaner than doing it in umpteen different error cases, and in any
	  case we don't usually bother generating output for success.
	- sync_pool: Don't check the pool state.  Make this the
	  responsibility of the several callers, which need to check for
	  different states.
	- damage_devs: In the damage-all-even-labels case, repeat the effort
	  to damage every vdev until it goes UNAVAIL.  Previously, sometimes
	  the pool would sync its labels to the device after the damage had
	  been done but before the pool found the damage itself.
	- clear_errors: Wait for the pool to become healthy rather than
	  requiring the 'zpool clear' to have this effect; resilvering will
	  not necessarily complete immediately; it's issued async from
	  clear.
	- remove_devs: After removing the device files, wait for each of
	  them to become UNAVAIL in the pool config.
