Juliana Fajardini 6e4a501e7c flowint: add isnotset support
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.

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

    requires: keyword foo;

Will require that Suricata supports the "foo" keyword.

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.

Juliana Fajardini 246acc7140 userguide: clarify flow:stateless explanation
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.

Philippe Antoine 0a1062fad2 detect/mqtt: move keywords to rust
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.

Ticket: 4863

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.
