fake_trx/data_dump.py: use 2 bytes to store message length
One byte may store a value in range [0x00, 0xff]. The maximal 0xff
value is 255 in dec, so a message length is limited to 255 bytes.
This is enough for GSM bursts, but not for EDGE.
Since this change, two bytes of header are used to store the
pending message length. All captures created before are not
supported anymore...

fake_trx/burst_send.py: implement DATA capture support
Previously, this tool was only able to read a hand-crafted text
file with bursts and send them via the DATA interface. This is
not so useful...
This change implements support of reading DATA capture files,
which can be generated e.g. by trx_sniff.py or burst_gen.py.
Both standart input (stdio) and text-files are not supported
anymore.
Usage example:
./burst_send.py -m L1 -i capture.bin --timeslot 2

fake_trx/burst_gen.py: add burst capture support
Now all generated bursts can be also written to a capture file,
using a new option called '--output-file'. If a file already
exists, bursts would be appended to the end. Otherwise a new
capture file is created.

fake_trx/trx_sniff.py: use DATADumpFile for capture writing
Since we have a separate class for DATA capture management now,
no need to implement the wheel - let's just use it!

fake_trx: implement classes for DATA capture menagement
This change introduces the following classes:
- DATADump - basic class, which contains methods to generate
and parse the a message header, and some constants.
- DATADumpFile - a child class, which contains methods to
write and parse DATA messages from capture files.
Usage example:
# Open a capture file
ddf = DATADumpFile("capture.bin")
# Parse the 10th message
msg = ddf.parse_msg(10)
msg.fn = 100
msg.tn = 0
# Append one to the end of the capture
ddf.append_msg(msg)
