* cygtls.cc (_cygtls::handle_threadlist_exception): Make an error fatal.

Browse Source 
* cygtls.h (sockaddr_in): Use header rather than defining our own structure.
* exceptions.cc (_cygtls::interrupt_setup): Use exact contents of sa_mask
rather than assuming tht current sig should be masked, too.
(_cygtls::call_signal_handler): Use more aggressive locking.
* gendef (_sigbe): Wait until later before releasing incyg.
(_sigreturn): Remove more arguments to accommodate quasi-sa_sigaction support.
(_sigdelayed): Push arguments for sa_sigaction.  More work needed here.
* signal.cc (sigaction): Implement SA_NODEFER.
* tlsoffsets.h: Regenerate.

* sigproc.cc (wait_sig): Use default buffer size of Windows 9x complains.
* pinfo.cc (_onreturn::dummy_handle): Remove.
(_onreturn::h): Make this a pointer.
(_onreturn::~_onreturn): Detect whether pointer is NULL rather than value is
NULL.
(_onreturn::_onreturn): Set h to NULL initially.
(_onreturn::no_close_p_handle): Set h to NULL.
(winpids::add): Initialize onreturn with value from p.hProcess immediately.
