Added files:

Log message:
	* cygtls.h (_cygtls::signal_exit): Delete from class.
	* exception.h (cygwin_exception): New class.
	(cygwin_exception::dumpstack): Declare new function.
	(cygwin_exception::context): Ditto.
	(cygwin_exception::dump_exception): Ditto.
	* exceptions.cc (cygwin_exception::dump_exception): Move into cygwin_exception
	class.  Accommodate new variable names.
	(cygwin_exception::dumpstack): Ditto stackdump -> dumpstack.
	(exception::handle): Move andreas processing earlier.  Defer signal processing
	decisions to the signal thread where they belong.  Pass exception information
	to sig_send via new siginfo_t si_cyg field.
	(ctrl_c_handler): Wait for SIGHUP signal to be processed since it could cause a
	process exit and we don't want races with thread exit lock.
	(signal_exit): Move back here from sigproc.cc.  Modify arguments and remove
	from sigpacket class.  Decide when to dump core based on signal type.
	(sigpacket::process): Handle exiting signals in context of threads rather than
	in the signal thread.  Signal debugger on non-Windows signals.  Remove
	setup_signal_exit call.
	* sigproc.cc (no_signals_available): Remove argument.
	(signal_exit_code): Delete.
	(close_my_readsig): Ditto.
	(_cygtls::signal_exit): Move to exceptions.cc.
	(sigproc_terminate): Don't attempt to terminate signal thread.
	(setup_signal_exit): Delete.
	(exit_thread): Use new si_cyg entry in siginfo_t.
	(sig_send): Just use empty initializer for si.  Accommodate change in
	no_signals_available argument.
	(wait_sig): Remove attempt to "go asynchronous" on process exit.  Delete
	__SIGEXIT handling.  Don't ever exit.
	* sigproc.h: Remove __SIGEXIT from signal enum.  Renumber.
	* include/cygwin/signal.h (siginfo_t): Add si_cyg entry.
