	cygwin         : ChangeLog child_info.h cygheap.cc cygheap.h 
	                 dcrt0.cc exceptions.cc sigproc.cc thread.cc 
	                 thread.h spawn.cc 

Log message:
	* child_info.h (cygheap_exec_info::sigmask): Declare new field.
	* cygheap.cc (init_cygheap::find_tls): Rename threadlist_ix -> ix.  Only take
	one pass through thread list, looking for eligible threads to signal.  Set a
	new param indicating that function has found a sigwait* mask.
	* cygheap.h (init_cygheap::find_tls): Reflect new parameter.
	* dcrt0.cc (parent_sigmask): New variable.
	(child_info_spawn::handle_spawn): Save parent's signal mask here.
	(dll_crt0_1): Restore parent's signal mask to tls sigmask as appropriate.  Call
	sig_dispatch_pending to flush signal queue when we can finally do something
	with signals.
	* exceptions.cc (sigpacket::process): Avoid attempting to handle signals if we
	haven't finished initializing.  Rely on the fact that find_tls will do mask
	checking and don't do it again.  Delete ill-named 'dummy' variable.
	* sigproc.cc (cygheap_exec_info::alloc): Save calling thread's signal mask in
	new sigmask field.
	(wait_sig): Try to debug when WFSO fails and DEBUGGING is defined.
	* thread.cc (pthread::set_tls_self_pointer): Make this a true automatic method
	rather than inexplicably relying on a thread parameter.
	(pthread::thread_init_wrapper): Accommodate set_tls_self_pointer change to
	non-static.  Initialize sigmask before setting tid or suffer signal races.
	* ehread.h (pthread::set_tls_self_pointer): Make non-static, delete parameter.
