This change is done to make keeping track of sample counter
at the input of the resampler easier from blocks connected
to its output. Each tag leaving the resampler has accompanying
"original_offset" tag with its offset before sample rate change.

When tag appears at the last sample of the ouput buffer
it will be added again in the next run of the work function.
Here this issue was solved by changing the codition so the
tag appearing at the end of the output buffer is not added.

This is the output format of rtl_sdr and hackrf_transfer and this would
allow direct channelization without an additional post processing.

Checking if freq_offset is None doesn't make sense currently
as it's always set to a float value by argparse (to 0 by default).

- Read bursts with pmt::deserialize directly from the std::filebuf
- Remove the unused unserialized variable
- Add tests
Since df978693 when the rx_time tags are present in the incomming stream
the gsm receiver adds fm_time to the burst's PMT and the bursts that
burst file sink writes becomes longer because of the additional field.
The burst file source block was expecting all burst to be 147 bytes long
and reading files with longer bursts was failing with an unhandled exception.

Argparse makes adding new parameters easier and
adds consistent way of handling default values of
parameters and printing of their help info.

An ability to shift the baseband frequency would allow one to
run both base stations and (OsmocomBB-based) mobile stations on
any frequency (e.g. in 2.4 GHz WiFi band)!
This is achieved by adding a given frequency offset to the
result of "ARFCN -> RX/TX frequency" calculation.
Usage example:
grgsm_trx --freq-offset -500M
Both RX (Downlink) and TX (Uplink) frequencies will be shifted
by 500 MHz back, e.g. tuning request to ARFCN 105 would result
in tuning the radio to 456.0 MHz (instead of 956.0 MHz).

The new option (-b --bind-addr) allows one to specify the bind
address for both DATA and CTRL interfaces. By default, '0.0.0.0'
is used, so there are no restrictions for the L1 source address.

Pleviously remote address for DATA interface was also used as the
bind address, what is definitely wrong. Let's change the API a bit
in order to allow one to specify a custom bind address.

When we receive a control command, we should not simply send the
response to the default destination, but send it back to the exact
IP/prt from which the command originated.
This ensures correct routing of responses even in case multiple
programs are interfacing concurrently with a control socket.

Setting this option allows one to reuse existing connections,
for example, by injecting CTRL commands or DATA bursts
into existing connections.

Previously it was required to call the UDPLink.shutdown() method
manually in order to close a socket. Let's do it automatically
using the destructor of UDPLink.

Instead of using the hard-coded default values in help message,
it makes sense to use a format string, and pass the actual
values when printing help.

Some UHD devices, such as UmTRX, require one to manually reset the
hardware clock, otherwise the burst transmission doesn't work.

In order to avoid clashes with OsmoTRX, which may be also
running on the same host, let's use a different port range
starting from 6700 by default.
This idea was introduced as a result of OS#2984.
