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.

Philippe Antoine 9146fc8957 doc: upgrade note about keyword tls.cert_subject
Following commit 5379b52af2
rules that use multiple times the keyword tls.cert_subject
will result in

Warning: detect: duplicate instance for tls.cert_subject

These rules likely meant to use a multi-buffer which is not the
case for tls.cert_subject (even if it was documented so).
