  Log:
  First in a series of changes to remove the now-unused Giant compatibility
  framework for non-MPSAFE network protocols:
  
  - Remove debug_mpsafenet variable, sysctl, and tunable.
  - Remove NET_NEEDS_GIANT() and associate SYSINITSs used by it to force
    debug.mpsafenet=0 if non-MPSAFE protocols are compiled into the kernel.
  - Remove logic to automatically flag interrupt handlers as non-MPSAFE if
    debug.mpsafenet is set for an INTR_TYPE_NET handler.
  - Remove logic to automatically flag netisr handlers as non-MPSAFE if
    debug.mpsafenet is set.
  - Remove references in a few subsystems, including NFS and Cronyx drivers,
    which keyed off debug_mpsafenet to determine various aspects of their own
    locking behavior.
  - Convert NET_LOCK_GIANT(), NET_UNLOCK_GIANT(), and NET_ASSERT_GIANT into
    no-op's, as their entire behavior was determined by the value in
    debug_mpsafenet.
  - Alias NET_CALLOUT_MPSAFE to CALLOUT_MPSAFE.
  
  Many remaining references to NET_.*_GIANT() and NET_CALLOUT_MPSAFE are still
  present in subsystems, and will be removed in followup commits.
