osmo-bts-trx/trx_if.c: request the newest TRXD header version

This change introduces the new command for TRXD header version
negotiation - SETFORMAT. If the transceiver does not support
the format negotiation, it would reject this command with
'RSP ERR 1'. Otherwise the response should be:

  RSP SETFORMAT <VER> <VER_REQ>

where VER_REQ is the requested version, and VER is the actual
version, which can be either equal or lower than VER_REQ. In
other words, the transceiver may not support the requested
version, but a lower one, for example:

  L1 -> TRX: CMD SETFORMAT 2
  TRX -> L1: RSP SETFORMAT 1 2

Unlike OsmoTRX, FakeTRX does not reject unknown commands, but
confirm them. Thus older versions of FakeTRX would always
respond with status code 0, corresponding to version 0:

  L1 -> TRX: CMD SETFORMAT 2
  TRX -> L1: RSP SETFORMAT 0 2
