* path.cc (mount_info::cygdrive_posix_path): Don't add trailing slash if

referring to something like c:\.
* dcrt0.cc (dll_crt0_1): Move uinfo initialization prior to sig_send
initialization to give signal thread a chance to finish.
* debug.cc (WFSO): Move to sigproc.cc
(WFMO): Ditto.
* exceptions.cc (interruptible): Allocate slightly more space for directory
just for paranoia's sake.
(call_handler): Eliminate nonmain argument.  Determine if main thread has set a
frame pointer and use it if so.
(sig_handle): Eliminate nonmain argument.
* net.cc: Record frame information in appropriate routines throughout.
* select.cc (select): Ditto.
* sigproc.cc: Use sigthread structure to record mainthread id throughout.
(sig_send): Record frame information for signal handler.
(wait_sig): Reflect argument change in sig_handle.
(WFSO): Move here and record frame information for signal handler.
(WFMO): Ditto.
* sigproc.h: Implement new "sigthread" class.  Implement "sigframe" class for
manipulating signal frame info.
* thread.cc (__pthread_kill): Use standard _kill() function rather than calling
sig_send directly.
* winsup.h: Eliminate ebp element from signal_dispatch class.
