Subject: Always zero all elements of siginfo_t throughout. * cygtls.h
 (_cygtls::thread_context): Declare new field. (_cygtls::thread_id): Ditto.
 (_cygtls::signal_exit): Move into this class. (_cygtls::copy_context):
 Declare new function. (_cygtls::signal_debugger): Ditto. * cygtls.cc
 (_cygtls::init_thread): Fill out thread id field. * exceptions.cc
 (exception): Change message when exception info is unknown. Copy context to
 thread local storage. (_cygtls::handle_exceptions): Avoid double test for
 fault_guarded.  Reflect move of signal_exit to _cygtls class.
 (sigpacket::process): Copy context to thread local storage.
 (_cygtls::signal_exit): Move to _cygtls class.  Call signal_debugger to
 notify debugger of exiting signal (WIP).  Call stackdump here (WIP).
 (_cygtls::copy_context): Define new function. (_cygtls::signal_debugger):
 Ditto. * tlsoffsets.h: Regenerate. * include/cygwin.h (_fpstate): New
 internal structure. (ucontext): Declare new structure (WIP).
 (__COPY_CONTEXT_SIZE): New define. * exceptions.cc
 (_cygtls::interrupt_setup): Clear "threadkill" field when there is no
 sigwaiting thread. (setup_handler): Move event handling into interrupt_setup.
