Virtio_Balloon implementation for DragonFly

- Initial check-in of fbsd virtio_balloon (freebsd/freebsd@1537078)
- Update virtio_balloon man page
- Fix vtballoon_alloc_intrs to deal nicely with number of provided interrupts.
- Use a backoff scheme when allocating vm_pages:
  - VM_ALLOC_NORMAL for normal (low memory presure) situation;
  - VM_ALLOC_SYSTEM + increased sleep timeout, for high memory presure circumstances.
  The latter will allow the system to swap other pages out if necessary.
- Implemented suggestions made by ivadasz
  - Added virtio_teardown_intr handling to vtballoon_detach
  - Added config_change_intr handling
  - Fixed virtio_setup_intr
- Add debug_level sysctl for tracing.
- Add collection of guest memory/pagefault statistics
- Completed/Updated header definitions
- Don't use VM_ALLOC_INTERRUPT. Add better inflate/deflate debug output to thread_sleep function

  with CPU cores assymetrically.  In particular, with the 2990WX,
  half the cores will have no memory associated with them.

* This was forcing DFly to allocate memory from queues belonging to
  other nearby cores, causing unnecessary SMP contention, as well
  as burn extra time iterating queues.

* Fix by calculating the average number of free pages per-core,
  and then adjust any VM page queue with pages less than the average
  by stealing pages from queues with greater than the average.
  We use a simple iterator to steal pages, so the CPUs with less
  (or zero) direct-attached memory will operate more UMA-like
  (just on 4K boundaries instead of 256-1024 byte boundaries).

* Tested with a 64-thread concurrent compile test.  systat -pv 1
  showed all remaining contention disappear.  Literally, *ZERO*
  contention when we run the test with each thread in its own jail
  with no shared resources.

* NOTE!  This fix is specific to asymetric NUMA configurations
  which are fairly rare in the wild and will not speed up more
  conventional systems.

* Before and after timings on the 2990WX.
