This system can easily be extended by independent authors without
collisions, something the old system with plain increasing integers did
not allow.
Do this by utilizing the previously unused message code `NETMSG_NULL`
which has a value of 0.
This works for engine and game messages, snapshot items and events.
This means that we have a reliable and fast way to query for extended info,
while also not wasting network bandwidth.
The protocol is designed to be extensible, there's four bytes space for
encoding more request types (currently zeroed), and there's one string in each
response packet and one string for each player available (currently the empty
string).
The protocol itself has no problems with more than 64 players, although the
current client implementation will drop the player info after the 64th player,
because it uses a static array for storage.
Also fixes#130, the player list is just sorted each time new player info
arrives.
It was horribly broken before. :) Only the first password set via
`sv_rcon*_password` worked, and that only due to a bug in `AddHashKey`
-- `AddHashKey` incorrectly assumed that only key slots greater than 0
are valid, but 0 is valid too.
Fix default passwords on password removal, fix no admin password being
generated if you only had `sv_rcon_mod_password` or
`sv_rcon_helper_password` set. Add an assert that would have caught our
mistake.
This lets 0.6.4 clients connect to DDNet servers again. Instead of doing
our own resend logic, just always send `sv_map_window` packets ahead and
let the Teeworlds network deal with possible resends.

This means that characters with accents or other things around them are
now considered the confusable with the base character.
Fixes#557. Fixes#575.
CSqlData is const for threadfunctions now to avoid modification from
within the threadfunctions as these might be called several times.
Previously this was a problem as ClearString could possibily be applied
multiple times to the same string.
To solve this the class CSqlString has been added. This class takes a
const char* and copies it. Additionally a clearstring is created from
the given const char*. This enables access to the original as well as
the cleared string safe for sql-statements.
sql_string_helpers got an own source file now.
A crashbug from CSqlServer has been fixed (pointer has not been set
back to 0)
