* 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.
