a5e237f50c The ASCII writer now supports a filter config option
'only_single_header_row' that turns the output into CSV format.

In that mode all meta data is skipped except for a single header line
with the fields names. Example:

    local my_filter: Log::Filter = [$name = "my-filter", $writer = Log::WRITER_ASCII, $config = table(["only_single_header_row"] = "T")];

56e359ca9d Fix ambiguity between composite table index and record ctor expressions.
For tables of a composite index type with the first type being a
record, membership checks with an inline index key could be
misinterpreted as a record constructor instead of an expression list.
E.g, if the table type is "global t = table[conn_id, bool] of count",
then checking membership like "[c$id, is_orig] in t" now works.

Addresses #80.

9e49703087 Improve auto-generated enum documentation.
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".

fd5eb23fa6 Remove byte count parameter from modbus events carrying register arrays
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_input_registers_response
    modbus_write_multiple_registers_request
    modbus_read_write_multiple_registers_request

c911d03c30 Adjust modbus register array parsing.
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

defed7b6f3 Adjustments to modbus test cases.
- 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.

9edbf3e53c Add GPRS Tunnelling Protocol (GTPv1) decapsulation.
This currently supports automatic decapsulation of GTP-U packets on
UDP port 2152.

The GTPv1 headers for such tunnels can be inspected by handling the
"gtpv1_g_pdu_packet" event, which has a parameter of type "gtpv1_hdr".

Analyzer and test cases are derived from submissions by Carsten Langer.

Addresses #690.

e835a55229 Add IPv6 support to signature header conditions.
- "src-ip" and "dst-ip" conditions can now use IPv6 addresses/subnets.
  They must be written in colon-hexadecimal representation and enclosed
  in square brackets (e.g. [fe80::1]).  Addresses #774.

- "icmp6" is now a valid protocol for use with "ip-proto" and "header"
  conditions.  This allows signatures to be written that can match
  against ICMPv6 payloads.  Addresses #880.

- "ip6" is now a valid protocol for use with the "header" condition.
  (also the "ip-proto" condition, but it results in a no-op in that
  case since signatures apply only to the inner-most IP packet when
  packets are tunneled).  This allows signatures to match specifically
  against IPv6 packets (whereas "ip" only matches against IPv4 packets).

- "ip-proto" conditions can now match against IPv6 packets.  Before,
  IPv6 packets were just silently ignored which meant DPD based on
  signatures did not function for IPv6 -- protocol analyzers would only
  get attached to a connection over IPv6 based on the well-known ports
  set in the "dpd_config" table.

a6d87fcab7 rename the update_finished event to end_of_data and make it fire in
more cases.

It will now not only fire after table-reads have been completed,
but also after the last event of a whole-file-read (or whole-db-read, etc.).

The interface also has been extended a bit to allow readers to
directly fire the event should they so choose. This allows the
event to be fired in direct table-setting/event-sending modes,
which was previously not possible.
