Spoike 402aa52362 misc fixes, tweaks, and hacks. 
qc rt target api now uses names instead of numbers. shaders can name such rendertargets in advance.
added timing info to qc profiling, instead of just opcodes executed.
added sv_showconnectionlessmessages, to show all messages that don't relate to a client, so omc can see if he's getting DDOSed easily.
try to show proper error messages with the xmpp plugin, at least for certain things.

/*
Network limitations:
googletalk:
username: same as gmail (foobar@gmail.com).
FIXME: need to test foobar@googlemail.com
auth mechanism: oauth2(tls+nontls) or plain(tls-only). no digests supported, so mitm can easily grab your password if they use certificate authority hackery, so DO NOT log in from work.
oauth2: I've registered a clientid for use with googletalk's network, but the whole web-browser-is-required crap makes it near unusable. We'll try it if they omit a password.
otherwise a complete implementation.
other users appear unresponsive and permanently away. this is a wtf on google's part and not something I can trivially work around. these people are really offline but have previously used 'google hangouts', and google insist on the UI nightmare infecting other clients too.
appears to hack avatar vcards into all presence messages, which is just an interesting thing to note as it seems to keep fucking up resulting in extra queries for avatar images.
facebook:
username: foobar@chat.facebook.com
auth mechanism: digest-md5, x-facebook-platform.
gateway implementation: no arbitary iq support (no invite/join/voice).
no roster control
completely untested. I've no interest in signing up to be tracked constantly (but somehow google is okay... go figure... I guess I'm just trying to avoid a double-whammy)
oauth2: no idea where to register a clientid, or what the correct addresses are. a google search implies they don't do refresh tokens properly. sticking with digest-md5 should work.
*should* work for chat.
msn:
username: foobar@messenger.live.com (NOT foobar@live.com - this will timeout)
auth mechansim: x-messenger-oath ONLY
non-standard unusable crap.
uses incorrect certificates. any client that doesn't warn about that is buggy as fuck.
probably doesn't have iq support, no idea, can't log in to test that
requires annoying see-other-host redirection.
no roster control
stun servers are listed in srv records for live.com and messanger.live.com but not messenger.live.com. retards.
oauth2: too lazy to register a clientid. stupid crap. I hate having to register everywhere.
ejabberd:
auth mechanism: digest-md5, scram-sha1, plain.
complete implementation. no issues.
may be lacking srv entries, depends on installation.
may have self-signed certificate issues, depends on installation.
client compat:
hangouts:
UI nightmare infects the entire network and thus other clients also.
voip not supported. does not advertise any extensions and thus no voip.
no file transfer support.
googletalk:
impossible to download from google any more. completely unsupported.
implements old version of jingle. voice calls appear to not work.
does not support SI file transfer.
not tested by me.
pidgin:
(linux) has issues with jingle+ice, and can easily be made to crash. voip uses speex. pidgin's ice seems vulnerable to dropped packets.
(windows) doesn't support voice calls
file transfer works.
otherwise works.
