  Modified files:
    sys/conf             options 
    sys/kern             kern_sx.c 
    sys/sys              sx.h 
  Log:
  Fix some problems with lock_profiling in sx locks:
  - Adjust lock_profiling stubs semantic in the hard functions in order to be
    more accurate and trustable
  - Disable shared paths for lock_profiling.  Actually, lock_profiling has a
    subtle race which makes results caming from shared paths not completely
    trustable. A macro stub (LOCK_PROFILING_SHARED) can be actually used for
    re-enabling this paths, but is currently intended for developing use only.
  - Use homogeneous names for automatic variables in hard functions regarding
    lock_profiling
  - Style fixes
  - Add a CTASSERT for some flags building
