- Properly fix the debug support for all the ASSERT's, VERIFIES, etc can be
  compiled out when doing performance runs.
- Bite the bullet and fully autoconfize the debug options in the configure
  time parameters.  By default all the debug support is disable in the core
  SPL build, but available to modules which enable it when building against
  the SPL.  To enable particular SPL debug support use the follow configure
  options:

  --enable-debug		Internal ASSERTs
  --enable-debug-kmem		Detailed memory accounting
  --enable-debug-mutex		Detailed mutex tracking
  --enable-debug_kstat          Kstat info exported to /proc
  --enable-debug-callb		Additional callb debug
