txtime_setter: clean up and simplify source code
...
This change formats the block implementation source code
according to a mix of GNURadio and the Kernel coding styles.
The main changes are:
- Limit line length to 80 columns
- Preffer the opposite conditions
- Do not use curly braces for single line loops / conditions

Fix: protections in txtime_setter against late bursts and bursts in too distant future.
...
Fixing bursts in too distant future is a bit problematic and better way than just looking at tx_time difference from current time would be desirable.
This way of fixing that issue can still cause that tx part will do nothing for about 10 seconds (after switching frequency from a BTS1 (with fn1) to BTS2 (with fn2) when fn1>fn2).

Fix: don't send SCH burst to the output if it wasn't correctly decoded
...
This had very bad effect of incorrect fn_time values coming into txtime_setter block.
They, subsequently, might have caused busts with tx_time values in distant future. The result on uhd sink is deadlock.

flow_control: implement pass / drop filtering policies
...
This change introduces a set of three modes for flow control
filters, one of which is default behavor and two extra modes
else described below:
- FILTER_POLICY_PASS_ALL
- FILTER_POLICY_DROP_ALL
Both modes are opposite, and make a filter either unconditionally
pass or drop all the data one gets to the input. They would be
usable for some external usage.

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.
