* cygwait.cc (cancelable_wait): Add some debugging-only output.
* exceptions.cc (sig_handle_tty_stop): Make sure that incyg is cleared when
exiting if we have no parent process. Only wait for signal_arrived.
(sigpacket::process): Make continue_now a bool. Delay sending signal_arrived
until the end. Make code more defensive to avoid calling signal handler when
stopped. Only set signal_arrived when stopped.
* sigproc.cc (sig_hold): Rename from sigCONT. Make static.
(sig_send): Accommodate sigCONT -> sig_hold rename.
(wait_sig): Ditto.
* sigproc.h (sigCONT): Delete declaration.
* fhandler_console.cc (fhandler_console::write): Use new '%0c' facility to
print characters. Change to paranoid to avoid excessive strace output.
* fhandler_tty.cc (fhandler_pty_master::accept_input): Make frequent strace
printf "paranoid" to help cut down on strace output size.
* signal.cc (sigsuspend): Add standard syscall strace output.
(sigpause): Ditto.
(pause): Ditto.
* cygtls.h (_cygtls::reset_signal_arrived): New function.
