HAMMER VFS - Use full-block undos for B-Tree nodes

* Use a full-block undos instead of small byte-range undos for
  B-Tree nodes.

  There is no bug here per-say, but we are trying to improve
  HAMMER's ability to recover after a power failure where a disk
  drive is writing to the platter at the time of the failure.
  While we have no control over any unrelated sectors that might
  get smashed by such an event, the concern is that sectors being
  specifically written might get corrupted beyond the ability for
  the byte-range undo to fix.

  The reason is that if, say, only 50 bytes in a B-Tree node need
  updating, HAMMER must still do a 16K physical write to disk, so
  really any portion of that 16K can wind up corrupt on a power
  failure, not just the 50 bytes being changed.

  So instead of writing a byte-ranged 50-byte UNDO we now write
  a 16K undo for B-Tree elements.

* The hope is that this will improve cases where HAMMER has become
  unmountable due to CRC errors in the B-Tree closer to the root of
  the B-Tree (which are usually updated to update only the mirror_tid)

kernel - Fix i386 pmap bug

* mpte will be NULL for KVM page table pages, there is no need to track
  the wire count.  Conditionalize-out the unwiring call.

* This is believed to be (this time for sure to the third power!) the

  action.  Adjust the trap code to only take the action if the frame's
  stack pointer matches the recorded expected stack pointer.

  Otherwise this might be a recursive trap and we definitely do NOT want
  to execute the on-fault stuff in that situation.

* Prior to these changes recursive traps during uiomove()s could result
  in a kernel stack so corrupt that finding the actual cause of the panic
  becomes impossible.  This is believed to be making life difficult for us
  trying to track down a particular i386 panic.
