digital: Complete overhaul of protocol handling
See documentation for details. In brief:
- digital_protocol_* classes added (replace packet header blocks)
- header_buffer class added
- Lots of QA
- default packet formatter: contains access code and payload length
fields.
- counter packet formatter: also contains the bits/sym in the payload
modulation and a packet number counter.
- Also adds QA code and the infrastructure for C++ QA code in
gr-digital.
- New block to use the packet formatter objects.
- The header and payload are transmitted as PDU messages out of different ports.
- header_buffer class for header formatting.
- Used by packet_formatter_x classes to more easily add and format
header data for transmission.
- New blocks that parse headers.
- Handles either hard or soft bits. Produces an info message to
instruct payload demod.
- 'receive mode' to header_buffer class.
- Designed to make extracting fields from the received header bits
easier for packet formatter classes. Use extract_field[N] to get
the different fields out of a collected set of header bits. *
Docs describing both functions with small examples for how to use
them.
- Don't force access code to be a multiple of 8
- need to verify everything else handles this correctly.
- Throw an exception in the ctor if setting the code failed and emit a
log message.
