Philippe Antoine f2c3776314 detect: log app-layer metadata in alert with single tx 
Ticket: 7199

Uses a config parameter detect.guess-applayer-tx to enable
this behavior (off by default)

This feature is requested for use cases with signatures not
using app-layer keywords but still targetting application
layer transactions, such as pass/drop rule combination,
or lua usage.

This overrides the previous behavior of checking if the signature
has a content match, by checking if there is only one live
transaction, in addition to the config parameter being set.

Juliana Fajardini 6e4a501e7c flowint: add isnotset support

code also following the same patterns.

Jason Ish 289ff25f5b requires: support requires check for keyword 
For example:

    requires: keyword foo;

Will require that Suricata supports the "foo" keyword.

Ticket: #7403
 9 months ago
Jason Ish 820a3e51b7 requires: treat unknown requires keywords as unmet requirements 
For example, "requires: foo bar" is an unknown requirement, however
its not tracked, nor an error as it follows the syntax. Instead,
record these unknown keywords, and fail the requirements check if any
are present.

A future version of Suricata may have new requires keywords, for
example a check for keywords.

Philippe Antoine 4ec90bd227 detect: absent keyword to test absence of sticky buffer 
Ticket: 2224

It takes an argument to match only if the buffer is absent,
or it can still match if the buffer is present, but we test
the absence of some content.

For multi buffers, absent matches if there are 0 buffers.

For file keywords, absent matches if there is no file.

Jason Ish 6ae5ae701b doc/userguide: generate eve documentation 
Add EVE documentation for QUIC and Pgsql to their respective sections of
the userguide.

Also add a complete EVE reference as an appendix.

Other protocols can be done, but its a manual process to document in the
schema, then add the glue to pull them into the documentation.

The documentation is generated during "make dist", or if it doesn't
exist, "conf.py" will attempt to generate the eve documentation for
building on Readthedocs.

Use sed + regex to replace all occurrences of suricata.yaml terms that

Also search for such terms in the eve-log.yaml partials file, as that
is referenced in the configuration section.
