DNS v3 logging fixes the discrepancies between request and response
logging with the main difference being queries always being placed in an
array.
Bug: #6281
V3 style DNS logging fixes the discrepancies between request and
response logging better dns records and alert records.
The main change is that queries and answers are always logged as
arrays, and header fields are not logged in array items.
For alerts this means that answers are now logged as arrays, queries
already were.
DNS records will get this new format as well, but with a configuration
parameter.

Add DNSRDataOPT struct and DNSRData enum type OPT.
Add OPT parsing function and test function.
Add DNSRData OPT type to lua.rs match.
Log OPT rdata.
Feature: 7011
Add additionals to DNSMessage struct.
Add parsing logic to populate additional section data.
Patch dns tests to account for additional section parsing.
Don't assume the ntlmssp version field is always present if the flag is
set. Instead keep track of the offsets of the data of the various blobs
and see if there is space for the version.
Inspired by how Wireshark does the parsing.

To avoid ambiguity, a single definition for base 64 decoding modes will
be used. The Rust base64 transform contains the definitions for the
existing mode types: Strict, RFC2045, RFC4648

This can happen with keyword filestore:both,flow
If one direction does not have a signature group with a filestore,
the file is set to nostore on opening, until a signature in
the other direction tries to set it to store.
Subsequent files will be stored in both directions as flow flags
are now set.
New warning from rustc.
The other option is to allow dead code, however this is more explicit,
and when they are read, its obvious they should be renamed.

On the way, convert unit test DetectSNMPCommunityTest to a SV test.
And also, make snmp.pdu_type use a generic uint32 for detection,
allowing operators, instead of just equality.
Implement special "isset" and "isnotset" modes.
"isset" matches if an IP address is part of an iprep category with any
value.
It is internally implemented as ">=,0", which should always be true if
there is a value to evaluate, as valid reputation values are 0-127.
"isnotset" matches if an IP address is not part of an iprep category.
Internally it is implemented outside the uint support.

For TCP streams, app proto stream reassembly can start earlier, instead
of waiting and queueing up data before doing so.

- transactions are now bidirectional
- there is a logger
- gap support is improved with probing for resync
- frames support
- app-layer events
- enip_command keyword accepts now string enumeration as values.
- add enip.status keyword
- add keywords :
enip.product_name, enip.protocol_version, enip.revision,
enip.identity_status, enip.state, enip.serial, enip.product_code,
enip.device_type, enip.vendor_id, enip.capabilities,
enip.cip_attribute, enip.cip_class, enip.cip_instance,
enip.cip_status, enip.cip_extendedstatus

Previously, it was looked for message in plain text, and base64
encoding was only handled for attachments.
This commit also fixes the buffering got such base64 data streamed
into urls finding, by buffering a beginning non-empty line,
and by ensuring that we run extraction on the last line,
even if it had no EOL.
Expose the raw stream earlier to the detection engine, as Pgsql can have
multiple messages per transaction and usually will have a message
complete within one TCP packet.

Before, the JsonBuilder object for the pgsql event was being created
from the C-side function that actually called the Rust logger.
This resulted that if another module - such as the Json Alert called the
PGSQL logger, we wouldn't have the `pgsql` key present in the log output
- only its inner fields.
Bug #6983
Remove maintainer-clean-local, this is not needed.
In distclean-local, remove "rust/dist" and "rust/vendor" as they are
created during "make dist".
In "clean-local", remove "rust/target" and "rust/gen" as they are
created during a normal "make".
