Pawel Jakub Dawidek 3650be51e2 - Reimplement I/O data allocation to prevent deadlocks.
Submitted by:	green

- Speed up synchronization process by using configurable number of I/O
  requests in parallel.
  + Add kern.geom.raid3.sync_requests tunable which defines how many parallel
    I/O requests should be used.
  + Retire kern.geom.raid3.reqs_per_sync and kern.geom.raid3.syncs_per_sec
    sysctls.
- Fix race between regular and synchronization requests.
- Reimplement raid3's data synchronization - do not use the topology lock
  for this purpose, as it may case deadlocks.
- Stop synchronization from pre-sync hook.
- Fix some other minor issues.
