Philippe Antoine c93e69830a detect/ssl: properly handle negation in ssl_version keyword
Ticket: 3220

DetectSslVersionMatch did not handle properly negation.
It could never match on a signatrue with ssl_version: !tls1.3
That is because, if we had such a signature and network traffic
with tls1.1, we were looking into DetectSslVersionData field
for tls1.1, which was not set, instead of looking at field
for tls1.3 which was set with negated flag.

Previous DetectSslVersionData was holding redundant information.
It did not need to have it for each ssl version, but just globally.
Also, it did not need to hold the version as a value in the array,
as it was redundant with the index of the array.

Jeff Lucovsky b02d9bb4f1 doc/luaxform: Remove init function from example
Issue: 8035

The `luaxform` transform doesn't support the `init` function. This
commit removes that from the example and clarifies how functions in the
Lua script are used.

Philippe Antoine d8cb00e795 detect/tcp: make tcp.flags a generic integer with bitflags
Ticket: 6724

Allows to use numerical values for example

Also fixes some unit tests that were returning 1 after goto error
FlagsTestParse05 especially took this path as
de->ignored_flags != (TH_SYN|TH_RST) was false
we had de->ignored_flags == 0xff ^ (TH_SYN|TH_RST)
And then, we had a match, instead of what the not-run code
was supposing.

Philippe Antoine 633180c93f detect/integers: generalize support for bitflags modifier
Ticket: 6724

Allows sugar syntax for bitflags keywords.
While the expressivity does not increase, because we could already
use numerial values with all generic integer modes, this modifier
prefix is used with the strings, and follows the syntax
that is already used for fragbits and tcp.flags keyword.
