Cygwin: select: revamp non-polling code for signalfd Rather than waiting for signalfd_select_wait in a thread, which is racy, create a global event "my_pendingsigs_evt" which is set and reset by wait_sig depending only on the fact if blocked signals are pending or not. This in turn allows to WFMO on this event in select as soon as signalfds are present in the read descriptor set. Select's peek and verify will then check if one of the present signalfds is affected.

In case we have to create a stackdump for a stack overflow condition, do so from a separate thread. Explain why. (sigpacket::process): Don't run signal_exit on alternate stack. (altstack_wrapper): Wrapper function to do stack correction when calling the signal handler on an alternate stack to handle a stack overflow. Make sure to have lots of comments.
