a fork from a non-main thread.
* dcrt0.cc (initial_env): Eliminate parameter and just send DebugBreak when
appropriate.
(dll_crt0_0): Reflect parameter change to initial_env.
(dll_crt0_1): Don't call initial_env.
(setjmp): Import, add sig stack handling. Store sig stack info.
(longjmp): Call stabilize_sig_stack. Restore sig stack info.
* config/i386/setjmp.c: Remove.
(sigfe.s): Ensure that sigfe.s will be regenerated if it does not exist.
* dll_init.cc (dll_dllcrt0): Simplify initializing tests.
* exceptions.cc (setup_handler): Detect when stub caller is either spinning or
has acquired the lock after being suspended to avoid windows problems with
suspending a win32 API call.
* cygtls.h (_cygtls::spinning): Declare new element.
* gendef: Remove unused _siglist_index and _siglist declaration.
(_sigfe): Set spinning element when potentially looping, waiting for lock.
(_sigbe): Ditto.
(_cygtls::lock): Ditto.
(_longjmp): Ditto.
* tlsoffsets.h: Regenerate.
* pinfo.cc (_pinfo::exit): Set final exit state here. Call sigproc_terminate
if invoked with 'norecord'. Clear any residual _cygtls stuff.
* winsup.h (exit_states): Define ES_FINAL.
* spawn.cc (spawn_guts): Don't call proc_terminate specifically when execing.
Let _pinfo::exit handle that case.
* sigproc.cc (wait_subproc): Always exit loop early when proc_loop_wait.
* init.cc (munge_threadfunc): Eliminate unused argument.
(dll_entry): Reflect above change in call to munge_threadfunc.
* cygtls.h (_cygtls::call_signal_handler): Rename from call_signal_handler_now.
(_cygtls::push): Make second argument mandatory.
(_cygtls::fixup_after_fork): Declare new function.
(_cygtls::lock): Ditto.
* cygtls.cc (_cygtls::fixup_after_fork): Define new function.
* dcrt0.cc (cygwin_finished_initializing): Define as bool.
(alloc_stack): Use _tlstop rather than arbitrary variable in probably vain
attempt to avoid strange fork problem on CTRL-C.
(dll_crt0_0): Remove obsolete winpids::init call.
* dll_init.cc (dll_dllcrt0): Detect forkee condition as equivalent to
initializing.
* winsup.h (cygwin_finished_initializing): Declare as bool.
* exceptions.cc (handle_exceptions): Rely on cygwin_finished_initializing to
determine how to handle exception during process startup.
(_cygtls::call_signal_handler): Rename from call_signal_handler_now.
(_cygtls::interrupt_now): Fill in second argument to push.
(signal_fixup_after_fork): Eliminate.
(setup_handler): Initialize locked to avoid potential inappropriate unlock.
Resume thread if it has acquired the stack lock.
(ctrl_c_handler): Just exit if ctrl-c is hit before cygiwn has finished
initializing.
* fork.cc (sync_with_child): Don't call abort since it can cause exit
deadlocks.
(sync_with_child): Change debugging output slightly.
(fork_child): Set cygwin_finished_initializing here. Call _cygtls fork fixup
and explicitly call sigproc_init.
(fork_parent): Release malloc lock on fork failure.
(vfork): Call signal handler via _my_tls.
* sigproc.cc (sig_send): Ditto.
* syscalls.cc (readv): Ditto.
* termios.cc (tcsetattr): Ditto.
* wait.cc (wait4): Ditto.
* signal.cc (nanosleep): Ditto.
(abort): Ditto.
(kill_pgrp): Avoid killing self if exiting.
* sync.cc (muto::acquire): Remove (temporarily?) ill-advised exiting_thread
check.
* gendef (_sigfe): Be more agressive in protecting stack pointer from other
access by signal thread.
(_cygtls::locked): Define new function.
(_sigbe): Ditto.
(_cygtls::pop): Protect edx.
(_cygtls::lock): Use guaranteed method to set eax to 1.
(longjmp): Aggressively protect signal stack.
* miscfuncs.cc (low_priority_sleep): Reduce "sleep time" for secs == 0.
* pinfo.cc (winpids::set): Counterintuitively use malloc's lock to protect
simultaneous access to the pids list since there are pathological conditions
which can cause malloc to call winpid.
(winpids::init): Eliminate.
* pinfo.h (winpids::cs): Eliminate declaration.
* pinfo.h (winpids::init): Eliminate definition.
