* cygtls.h (_cygtls::push): Inline. (_cygtls::interrupt_now): Change signal number argument to siginfo_t argument. (_cygtls::interrupt_setup): Ditto. (_cygtls::set_siginfo): Delete declaration. (_cygtls::reset_signal_arrived): Don't reset signal_arrived signal. Just reset flag. * exceptions.cc (_cygtls::interrupt_now): Reflect argument changes. Pass si to interrupt_setup. (_cygtls::interrupt_setup): Reflect argument changes. Fill out tls infodata here using passed-in si. Use si.si_signo instead of sig. (sigpacket::setup_handler): Move this function into sigpacket class. Use si field from the class as appropriate. (sigpacket::process): Don't call tls->set_siginfo here since setup_handler could fail. Eliminate now-unneeded sig argument. * sigproc.h (sigpacket::setup_handler): Move setup_handler to this class.
