The names of enum types are tracked so that variables holding a value
of a given enum type can generate a reference to it instead of just
listing the type as a generic "enum".
* origin/topic/dnthayer/bytes-to-double:
Portability improvement (data alignment issues)
Add test cases for the bytestring_to_double BIF
Add a new BIF "bytestring_to_double"
Closes#908.
Instead of these events being generated for invalid byte count values
(they should always be even, not odd), a protocol_violation is raised.
modbus_read_holding_registers_response
modbus_read_input_registers_response
modbus_write_multiple_registers_request
modbus_read_write_multiple_registers_request
modbus_read_write_multiple_registers_response
modbus_read_fifo_queue_respons
For modbus message types that include variable amount of register values
(uint16[]), setting a &length attribute without an explicit array size
could trigger a parsing assertion since it allows for the "element" data
pointer to travel past the "end of data" (e.g. when &length is odd).
This is changed to now give both an array size and &length to earlier
terminate the parsing of elements before the assert is checked and
so a single out-of-bound check can be done for the entire array
(leaving off &length causes an out-of-bound check for each element).
Added another parameter to modbus events that carry register arrays to
the script-layer which indicates the associated byte count from the
message (allowing for invalid values to be detected):
modbus_read_holding_registers_response
modbus_read_input_registers_response
modbus_write_multiple_registers_request
modbus_read_write_multiple_registers_request
modbus_read_write_multiple_registers_response
modbus_read_fifo_queue_response
- Added a test for binpac exception handling -- the generated code
should use "binpac::Exception" and not "Exception" for exception
handling logic to avoid accidental overshadowing by
the analyzer-specific type "binpac::ModbusTCP::Exception", which
could lead to interesting asserts being triggered in binpac.
- Update baseline for the event coverage test -- seems that more
events get generated with working exception handling in the generated
binpac parser code.
- Coverage baseline was giving wrong number of events covered.

Small modbus documentation update and tiny refactoring.
Final touches to modbus analyzer for now.
Major revisions to Modbus analyzer support (not quite done yet).
put some make-up on Modbus analyser

A couple of lookup_hostname_txt fixes.
Reverting the earlier function-join during merging.
* vlad/topic/vladg/dns_txt_queries:
DNS TXT support
I've tweaked it a little bit, still seems to work ...
I'd like to add a test for this but I'n not quite sure how to do that.
We'd have to hardcode a destination server that then'd be contacted
each time the test-suite runs.

- I added this to the base scripts because it's very minimal overhead
and we get questions about this all the time. Now that reporter
messages are printed to the console, people will see the message
clearly if they have bad checksums.
- There are still some broken events in the modbus analyzer because
I don't have traffic to test with (coil and record related events primarily).
- There are a few example scripts in policy/protocols/modbus
As opposed to creating weirds for e.g. "binpac::ExceptionOutOfBound".
The protocol_violation will also result in the disabling of the
analyzer by default.
Looks like the code in this function is getting ready for some
refactoring. Leaving that for another time though ...
Closes#909.
