Bram Matthys c22207c4ca Drop cf_ prefix from ConfigFile and ce_ prefix from ConfigEntry structs.
Also rename them to describe better what they do.

ConfigFile:
cf_filename -> filename
cf_next -> next
cf_entries -> items

ConfigEntry:
ce_fileptr -> file
ce_varlinenum -> line_number
ce_fileposstart -> file_position_start
ce_fileposend -> file_position_end
ce_sectlinenum -> section_linenumber
ce_varname -> name
ce_vardata -> value
ce_cond -> conditional_config
ce_entries -> items
ce_next -> next
ce_prevlevel -> parent

Also add doxygen docs for both structs.

Bram Matthys ee9db59d36 Fix two more small memory leaks on REHASH.
Now we are at zero leaks again with ASan, or so it seems.

Bram Matthys 5237ebaabc Fix crash in 5.2.0-rc1: don't call flood_limit_exceeded_log() if a remote
server causes the target flood protection limit to be hit for a target
user or a channel.

Bram Matthys 5acef88ceb All violatons of target-flood, nick-flood, join-flood, away-flood,
invite-flood, knock-flood, max-concurrent-conversations are now
reported to opers with the snomask 'f' (flood).

Bram Matthys 04a45e8b83 Fix targetfloodprot module not exempting U-Lines (only matters if not +o).
It is highly recommended that services pseudo users all have +o since
there are likely many places where ULines don't bypass a restriction while
opers do. But still, this particular issue has been fixed, it caused
unexplained loss of messages which looked rather mysterious.

Bram Matthys df5fd4e537 Adjust default set::anti-flood::target-flood rates to:
set {
    anti-flood {
        target-flood {
            channel-privmsg 45:5;
            channel-notice 15:5;
            channel-tagmsg 15:5;
            private-privmsg 30:5;
            private-notice 10:5;
            private-tagmsg 10:5;
        };
    };
};

Max 45 messages in 5 seconds means max 540 messages per minute,
with a peak of (surprise) 45 messages per 5 seconds...
That should be sufficient for every legit channel, right?
How can you chat if you get more than 9msgs/sec for 5 seconds straight?
Maybe I am even too liberal with these limits?

NOTICE and TAGMSG get lower limits because they are far less used
and have other concerns (eg: ringing a bell for NOTICE).

The default limits may be changed in later versions of UnrealIRCd
based on feedback and more insight in (big) channel rates.

Bram Matthys a259227424 New feature set::anti-flood::target-flood, provided by targetfloodprot module.
This limits X per Y messages for targets, regardless of sender. See docs:
