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.
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.

the data is encrypted.
These records may contain cipher lists for instance.

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.

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.
