Hello pespin, laforge, Jenkins Builder, Hoernchen, 

I'd like you to reexamine a change. Please visit

to look at the new patch set (#5).

Change subject: trx_toolkit/ basic TRXD version 0x01 support

trx_toolkit/ basic TRXD version 0x01 support

Since the new TRXD header format has been introduced, FakeTRX needs
to be able to fill it correctly. In particular, the following:

  - Modulation, which can be determined from the burst length;
  - Training Sequence Code (and set), which needs to be detected
    by comparing the burst bits of L12TRX message against known
    training sequences (only GMSK and the default TS set for now);
  - C/I (Carrier-to-Interference ratio), which can be simulated
    later on, as instructed on the TRXC interface ('FAKE_CI').

The actual TRXD header version is stored in the instance of class
DATAInterface. By default (at startup), legacy version 0 is used.
The version negotiation is supposed to be performed on the TRXC
interface, and to be implemented in a follow-up change.

Different Transceivers may use different header versions, thus in
FakeTRX.send_data_msg() we need to override the original version
of the L12TRX message, and generate the corresponding PDU.


  - NOPE / IDLE indications are not (yet) supported;
  - TSC detection: GMSK modulation only.
