                          thr_priority_queue.c thr_private.h

  Log:
  Add code to support thread debugging.
  1. Add global varible _libkse_debug, debugger uses the varible to identify
     libpthread. when the varible is written to non-zero by debugger, libpthread
     will take some special action at context switch time, it will check
     TMDF_DOTRUNUSER flags, if a thread has the flags set by debugger, it won't
     be scheduled, when a thread leaves KSE critical region, thread checks
     the flag, if it was set, the thread relinquish CPU.
  
  2. Add pq_first_debug to select a thread allowd to run by debugger.
  
  3. Some names prefixed with _thr are renamed to _thread prefix.
  
  which is allowed to run by debugger.
