Manual trims fall into the category of long-running pool activities which people might want to wait synchronously for. This change adds support to 'zpool wait' for waiting for manual trim operations to complete. It also adds a '-w' flag to 'zpool trim' which can be used to turn 'zpool trim' into a synchronous operation.

# DESCRIPTION:
|
|
# Verify manual trim pool data integrity.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create a pool on sparse file vdevs to trim.
|
|
# 2. Generate some interesting pool data which can be trimmed.
|
|
# 3. Manually trim the pool.
|
|
# 4. Verify trim IOs of the expected type were issued for the pool.
|
|
# 5. Verify data integrity of the pool after trim.
|
|
# 6. Repeat test for striped, mirrored, and RAIDZ pools.
