* cygtls.h (_cygtls::el): New field.

(_cygtls::handle_exceptions): New function declaration.
(_cygtls::handle_threadlist_exception): Ditto.
(_cygtls::init_exception_handler): Ditto.
(_cygtls::init_threadlist_exceptions): Remove arg from declaration.
* cygtls.cc (_cygtls::call2): Don't initialize exceptions here.
(_cygtls::init_thread): Do it here instead and use member function.
(_cygtls::handle_threadlist_exception): Move into _cygtls class.
(_cygtls::init_exception_handler): Ditto.  Rely on existence of 'el' memmber in
_cygtls.
(_cygtls::init_threadlist_exceptions): Ditto.
* dcrt0.cc (dll_crt0_1): Remove exception_list definition and setting since it
now commonly resides in the tls.
* exceptions.cc (init_exception_handler): Move to cygtls.cc.
(init_exceptions): Ditto.
(rtl_unwind): New, safe wrapper function for RtlUnwind.
(_cygtls::handle_exceptions): Move to _cygtls.  Call rtl_unwind to unwind
frames and eliminate copying of structures.  Put address of failing instruction
in si_addr, not the address on the stack.  Return 0 to indicate that we've
handled this exception.
* external.cc (cygwin_internal): Make CW_INIT_EXCEPTIONS a no-op.
* sigproc.cc (wait_sig): Accommodate argument change to
_cygtls::init_threadlist_exceptions.
* tlsoffsets.h: Regenerate.
* include/exceptions.h (exception_list): Add more stuff to the exception list.
Apparently windows needs this?
(init_exceptions): Remove bogus declaration.
* include/cygwin/signal.h (SI_USER): Redefine as zero as per SUSv3.
* thread.cc (pthread_kill): Set si_pid and si_uid.
* timer.cc (timer_thread): Set si_code to SI_TIMER.
