that the information needed for evaluation and context is included in
the commit message.

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.
Similar keywords use `isnotset`, while `flowint` only accepted `notset`
Opted to change the code, not only the regex, to keep the underlying
code also following the same patterns.
Task #7426
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.

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.
Since enabling custom logging will replace the extended logging, thus
possibly leading to certain fields disappearing from the logs, mention
this aspect.

Bug #7333
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.

So as to avoid quadratic complexity in libhtp.
Make the limit configurable from suricata.yaml,
and have an event when network traffic goes over the limit.
Use sed + regex to replace all occurrences of suricata.yaml terms that
used underscore for their up-to-date dash version.
Also search for such terms in the eve-log.yaml partials file, as that
is referenced in the configuration section.
commands used:
sed -i 's/\(^ *[a-z]*\)_\([a-z]*:\)/\1-\2/g'
sed -i 's/\(^ *[a-z]*\)_\([a-z]*\)_\([a-z]*:\)/\1-\2-\3/g'
Some other instances were found manually.
Task #7260
If a stream-only rule matches, and we find a tx where we
want to log the app-layer data, store into the tx data that
we already logged, so that we do not log again the app-layer metadata

Although the `prune-flows` option was removed with a5587fec2e,
when documentation for the suricata.yaml config file was added with
b252b0d, this option was also included - as has remained until now.
They have updated their docs domain, leading to the link we had
returning a 404.
Also checked the other links. Although some seem to only contain old
traffic, they all still work.
This ensures that the correct spelling of the `security_result` EVE
field for RFB (as opposed to `security-result`) is also reflected in the
documentation.
Ticket: #7210
While not incorrect, the previous wording made the sentence almost
paradoxical. While at it, also highlight a side effect that might not be
so clear to users.

Adds frames for SSH records, that come after banner, and before
the data is encrypted.
These records may contain cipher lists for instance.
Ticket: 4863
On the way, convert some keywords to use the first-class integer
support.
And helpers for pure rust the support for multi-buffer.
Move the C unit tests about keyword mqtt.protocol_version
to unit tests for generic integer parsing, and test version 5
instead of testing twice version 3.
Also iterate all tx's messages for reason code as is done for other
keywords.
And allow detection on empty topics.
