Changes:
- pthread_barrier_wait() intercept now passes the information to the DRD
  tool whether or not this function returned
  PTHREAD_BARRIER_SERIAL_THREAD. This information is now displayed when
  the command-line option --trace-barrier=yes has been specified.
- Changed the cleanup functions for client objects that are called just
  before a thread stops into callback functions.
- Added DRD_(clientobj_delete_thread)().
- Removed DRD_(clientobj_resetiter)(void) and DRD_(clientobj_next)().
- Added test for race conditions between pthread_barrier_wait() and
  pthread_barrier_destroy() calls. An error message is now printed if
  this condition has been detected.
- Bug fix: pthread_barrier_delete() calls on barriers being waited upon
  are now reported.
- Removed DRD_() wrapper from around the name of some static variables and
  functions.
