select.c: Introduce support for signalfd
The signalfd(2) mechanism of Linux allows signals to be delivered
and processed via normal file descriptor I/O. This avoids any of the
usual problems about re-entrancy of signal processing, as signals can
be processed from the osmocom select() loop abstraction just like any
other event.
