  Modified files:
    sys/kern             kern_sx.c 
    sys/sys              sx.h 
  Log:
  - Add trylock variants of shared and exclusive locks.
  - The sx assertions don't actually need the internal sx mutex lock, so
    don't bother doing so.
  - Add a new assertion SX_ASSERT_LOCKED() that asserts that either a
    shared or exclusive lock should be held.  This assertion should be used
    instead of SX_ASSERT_SLOCKED() in almost all cases.
  - Adjust some KASSERT()'s to include file and line information.
  - Use the new witness_assert() function in the WITNESS case for sx slock
    asserts to verify that the current thread actually owns a slock.
