[SR-Users] flags definition in kamailio.cfg + 5.2 documentation

Bringing in few more details ...

The named flags feature was added by SER developer during 2005-2008,
when Kamailio (well, openser at that time) and SER were different
projects. In 2008, as we started merging the source trees of Kamailio
and SER back in one repo (which became what is not Kamailio project),
named flags were propagated.

However, as for a personal experience, I never took the time to play
with them to see if they can be used "everywhere" -- for sure you can
use then in setflag/resetflag/isflagset functions, but I am not sure if
they work for branch flags and module parameters, or other places where
a flag index is expected.

In Kamailio we had the #!define feature that allowed to give a "name"
for a flag and that's how we have in default kamailio.cfg -- somewhere
at the top you can see #!define for FLT_* and FLB_* flags.

Cheers,
Daniel
