trx_interface: implement built-in timeslot filter
...
There is a dedicated block named 'Burst Timeslot Filter', which
could be used, but one doesn't expose the API to change the
timeslot index 'on fly'.
This change implements built-in timeslot filter in 'TRX Interface'
block, which will be used until the proper block expose API.

Implement transceiver interface
...
This change introduces a new block 'TRX Interface', which is aimed
to provide an interface for external applications, such as Osmocom
MS side stack implementation - OsmocomBB. Currently one allows to
exchange raw GSM bursts between GR-GSM and other applications.
Moreover, there is a new 'trx.py' application, which implements a
simple follow graph, where all demodulated bursts are being sent
to external application via UDP link provided by 'TRX Interface'.
OsmoTRX (Osmocom's fork of OpenBTS transceiver) like control
interface is used to initialize, configure, start and stop the
application. Messages on this interface are human readable ASCII
strings, which contain a command and some related parameters.
