receiver/time_sample_ref: SDR hardware time tracking
...
Gr-gsm's receiver needs a stream of samples with sampling frequency that
is integer multiply of gsm symbol rate. Many hardware receivers don't
support such rates, and even if they do there might be error in their
time source. Sample rate is adapted and corrected with use of a resampler.
Moreover corrections are applied in the runtime so resampler's resample
rate is changed dynamically. Those changes need to be tracked in order
to be able to track time of the hardware after resampling.
Hardware time tracking is needed to enable triggering of events in the
hardware (i.e. frequency changes, burst transmissions).
Changes were made in time_sample_ref and receiver in order to enable
SDR hardware time tracking.

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.

receiver_impl.cc: refactor the source code
...
This change formats the receiver implementation source code
according to a mix of GNURadio and the Kernel coding styles.
The main changes are:
- Line length limit is 80 columns
- Usage of /* comments */ is prefered
- Do not use curly braces for single line loops / conditions
For more details, see:

Removed boost timer from clock_offset_control to avoid race conditions.
...
The time is now tracked by the receiver based on samples count and send through the 'measurements' interface to the clock_offset_control.
clock_offset_control takes time into account during fcch_search.

Added capability to receive multiple channels of a single BTS to the receiver. It is now possible to receive bursts on channels for which frequency hopping was used. Changed examples to work without hierarhical GSM Receiver block.

First step to add multichannel capability to the GSM receiver. At this moment it might still contain debuging code. The training sequence number for non C0 channels is embedded in the code.
