  Log:
  Push Giant down a little further:
  - no longer serialize on Giant for thread_single*() and family in fork,
    exit and exec
  - thread_wait() is mpsafe, assert no Giant
  - reduce scope of Giant in exit to not cover thread_wait and just do
    vm_waitproc().
  - assert that thread_single() family are not called with Giant
  - remove the DROP/PICKUP_GIANT macros from thread_single() family
  - assert that thread_suspend_check() s not called with Giant
  - remove manual drop_giant hack in thread_suspend_check since we know it
    isn't held.
  - remove the DROP/PICKUP_GIANT macros from thread_suspend_check() family
  - mark kse_create() mpsafe
