Re: quake3-master-getservers summary patch

I fixed the problems you pointed out. It seems to be really hard to
find out what protocol 43 is. I tried scanning some of the servers.
Nmap identifies some of them as quake (1 I suppose) servers, while
some give indication that they might be quake3 servers. The problem is
that they could also be other games that are based on the quake3
engine. I really do not know.

I try to get my quake3-info script draft out one of these days. I have
kept it back while I have been wondering how the master works, but
also because it only supports quake3. Maybe it is useful for debugging
master servers, or can work as a basis for the multi-game version.

Here is a patch that extends quake3-master-getservers.nse with a
function that displays the amount of game servers for each game sorted
by popularity. It adds a postrule to the script and creates a summary
for all scanned quake3 master servers. Try running
nmap -sU -A -PN -p 27950 dpmaster.deathmask.net master.quake3arena.com
after applying the patch to quake3-master-getservers.nse.

There might be a bug here. It looks like the code is trying to avoid
adding the same (server, protocol) pair twice for the same master. But
it appears that the "if" condition will always be true. Shouldn't the
"filter[key] = true" line be moved inside the "if", like is done with
mfilter below?

What is the purpose of mfilter and mcount?

Please change the output to use the tab library, which will handle all
the space-padding for you.

| quake3-master-getservers:
|   1. Quake III Arena, or Urban Terror (68)   193 server(s)
|   2. unknown (43)                            154 server(s)
|   3. OpenArena (71)                          142 server(s)

Do you know what game protocol 43 is, as it seems to be common?
