apps/trx: handle MEASURE command
...
As the actual power measurement isn't implemented yet, we will
emulate this process sending random power levels from specified
range.

apps/trx: handle SETSLOT command
...
Currently, this command is used only to (re)configure built-in
timeslot filter of 'TRX Interface' block. Channel configuration
number, provided as the second parameter of command, is ignored.

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.

trx_interface: set proper burst type in GSMTAP header
...
If received burst is a RACH burst, one should contain the RACH
synchronization sequence (GSM 05.02 Chapter 5.2.7) and long
guard period filled by 0x00.

interface are not used, let's keep the protocol compatibility
and fill them by 0x00.

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.
