  Modified files:
    lib/libpthread       pthread.map 
    lib/libpthread/thread Makefile.inc 
  Added files:
    lib/libpthread/thread thr_execve.c 
  Log:
  Add a wrapper for execve().  The exec'd process must be started with
  the signal mask and pending signals of the calling thread.  These
  are stored in userland in libpthread.
  
  There is a small race condition in this patch which could cause
  problems if a signal arrives after setting the (kernel) signal
  mask and before exec'ing.  The thread's set of pending signals
  also are not yet installed in the exec'd process.  Both of these
  will be corrected with the addition of a special syscall.
