Throughout, eliminate argument to sig_dispatch_pending.
* exceptions.cc (setup_handler): Move non-interruptible condition handling (back) to wait_sig (as suggested by Pierre Humblet). (set_process_mask): Don't worry about calling sig_dispatch_pending from sigthread since it is detected in the function anyway. (sig_handle): Eliminate thisproc arg. Don't call sig_dispatch_pending on SIGCONT since that should happen automatically. * sigproc.cc (sig_dispatch_pending): Eliminate justwake argument. Just return when called from sigthread. (wait_sig): Change some variables to bool. Change inner while to an if. Move uninterruptible signal handling here. (sigproc_terminate): Don't call sig_dispatch_pending. Just increment semaphore on exit. * speclib: Use slightly different (but still flawed) method for determining symbols to extract from libraries.
