Client's can run string commands on the server with no rate limit. This means when you run 50k+ commands that are unknown, or spam 30k 'status' commands, you will be able to hang the server for 800/1200ms (15k/30kms if script printing to console is enabled!). Although the netchan processing budget system will kick you, the damage has already been done at this point. This change effectively breaks the ability to DOS the server from the client using networked string commands.
In easier words; binding 'status' to your mousewheel will get you kicked from the server, without hitching the server.
* Use 'CClient::Disconnect(..)' for all kicks and bans (this automatically clears the entire CClient slot, and removes the net channel).
* Only force disconnect when 'CNetChan::m_nSignonState' has a value that is not NULL.
* Clear the ServerPlayer slot on 'CClient::Disconnect(..)' and 'CClient::Connect(..)'.
* Only kick player for NetChannel overflow when value exceeds processing budget (not equals).
Implement net message process budget (channel gets removed if value is exceeded).
Use 'net_processLimit' to enable the implementation on the server. It will get enabled by default after testing and some cleanup. This helps against people trying to slow the server down by spamming net messages with a higher rate, e.g. using 'bind "mousewheel_up" "status"'.
* Fix all compiler error for GameSDK on S0 and S1.
* Remove some unused patterns and globals (launch performance gains of 100ms).
* Remove most duplicate patterns.
* Relocate globals from engine to a more appropriate location.
* Renamed some unknown vars to a more appropriate name (most of these where obtained a while back, but as we reversed more parts of the engine, some of these vars become known).
* Renamed some vars to fit the naming convention used in the SDK.
* Fixed pattern debug logging using the wrong pointer, thus displaying the wrong address.
* Mostly rebuild CServer structure.
* Partially rebuild CNetworkStringTable structure.
* Partially rebuild CNetworkStringTableContainer structure.
* Removed redundant patterns which are now covered in the data structure.
Moved server/client headers and implementations into dedicated subfolder.
Renamed Some classes to match the game binary (e.g. CBaseClient is now CClient).
Removed redundant files.
