Add osmo_timerfd_* functions for osmo_fd-wrapped timerfd
Linux offers file descriptor based periodic (interval) timers,
which can achieve a higher precision than our userspace based
timers and which can be slave'd to CLOCK_MONOTINIC or other clock
sources. Let's add some code for osmo_fd wrapped versions that
integrate well with our select() abstraction.
The code has been used in osmo-bts-trx since June 2017 (change-id
I51b19adde14ebb7ef3bb863d45e06243c323e22e), and I'm just renaming
and moving it to libosmocore here. After a merge, the osmo-bts
implementations can be removed in favor if this one.
