osmo-bts-trx: implement Temporary Overpower for SACCH/FACCH

GSM/EDGE Evolution and Performance, Section 12.3 suggests Temporary
Overpower as another solution to improve SACCH/FACCH performance in
case of bad C/I. The idea here is that you increment the DL transmit
power by 2..4dB only for FACCH/SACCH bursts, while keeping all voice
bursts at the lower (normal) level as determined by BS power control.

SACCH blocks can be recognized by the channel type, since they're
always transmitted in specific frames of a multiframe.  FACCH blocks,
however, are not predictable and can substitute voice blocks at
(almost) any time.  Thus we need to mark FACCH bursts as such in
the logical channel handlers (using TRX_BR_F_FACCH).
