  Modified files:
    sys/geom/raid3       g_raid3.c g_raid3.h g_raid3_ctl.c 
  Log:
  - 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.
