Add loopback support for PDTCH
This add support for BTS-side lookback of PDTCH channels.
If lchan-loopback is enabled, We take the uplink frames as received in
PH-DATA.ind and put them into the dl_tch_queue for that lchan. When we
receive PH-RTS.ind, we dequeue frames from that queue and transmit them
in downlink. If no frame is found in queue, we transmit an empty
(all-zero) frame of 23 bytes (CS-1).

TRX: Use timerfd and CLOCK_MONOTONIC for GSM frame timer
using gettimeofday() is not suitable for the GSM frame timer, as it
relies on the normal 'wall clock' system time, which may be adjusted by
ntp, gps or other means at runtime.
Switching to a different clock source means we cannot use
osmo_timer_list anymore, but timerfd integrates just fine with our
libosmocore select() loop handling.
