* cygtls.h (CYGTLS_INITIALIZED): Change to a little more unlikely value.

Browse Source 
(CYGTLSMAGIC): Delete.
* dcrt0.cc (dll_crt0_0): Call sigproc_init during init startup.
(_dll_crt0): Don't worry about sync_startup.  Just wait for sigthread here.
* dll_init.cc (cygwin_detach_dll): Only pick up tls version of retaddr if we
have a valid tls.
* fork.cc (frok::child): Remove sigproc_init initialization since it happens
much earlier now.
* gendef: Recognize SIGFE_MAYBE.
(fefunc): Generate calls to _sigfe_maybe, if appropriate.
(_sigfe_maybe): New function.
* init.cc (search_for): Always initialize search_for, even on fork.
(calibration_thread): Delete.
(calibration_id): Delete.
(prime_threads): Delete.
(munge_threadfunc): Remove calibration_thread special case.  Avoid calling
thread function if we haven't yet hit the "search_for" thread.
(dll_entry): Remove prime_threads call.  Only call munge_threadfunc when
hwait_sig is active.  Ditto.  for _my_tls.remove ();
* sigproc.cc (hwait_sig): Make global.
(sigproc_init): Don't bother with sync_startup.
(sig_send): Treat flush as a no-op when signals are held.
(wait_sig): Cause signals to be held after fork.
