r20930: use sigaction() instead of signal()

add support for sa_flags argument to event_add_signal(). These are
passed to sigaction(). Special handling is provided for SA_RESETHAND
(which tells the event system to remove the handler after the signal)
and SA_SIGINFO which allows the siginfo structure to be received per
signal
(This used to be commit 1bb10b6cf7d717ad21834e73a4ca4b22b5fb6f0a)
