Methods called from the UDP voice thread:

	void Server::run(); // obviously!

	bool Server::checkDecrypt(ServerUser *u, const char *encrypt, char *plain, unsigned int len);

	void Server::sendMessage(ServerUser *u, const char *data, int len, QByteArray &cache, bool force);

	void Server::processMsg(ServerUser *u, const char *data, int len); // via Server::sendMessage() above.



Unsynchronized access:

	Server::run:

		- User->csCrypt.isValid()
		- User->uiSession
		- User->sUdpSocket
		- User->saiUdpAddress

	Server::checkDecrypt

		- Validity check at the beginning of the function:
			- Various access to u->csCrypt
				- isValid
				- decrypt()
				- tLastGood
				- tLastRequest
			- User->uiSession

	Server::sendMessage

		- User->bUdp
		- User->sUdpSocket
		- User->csCrypt.isValid()
		- User->saiUdpAddress

	Server::processMsg
		User->sState
		User->bMute
		User->bSuppress
		User->bSelfMute

		SENDTO macro
			- User->bDeaf
			- User->bSelfDeaf
			- User->ssContext

		User->bwr
