fteqw/engine/client/sys_win.c
Spoike 25ef3f02db Couple of bugs fixed - other-player prediction, net_preparse crashes, q2 gamecode no longer crashes. 
Throttle getstatus requests (so we don't end up being used for udp escilation (d)dos attacks so usefully/expensively).
Added cl_predict_players_frac. vanilla QW effectively had a hardcoded value of 0.5.
Added simple fps preset menu, which keeps on appearing until they actually pick one. mwahaha.
Quit menu offers to save settings if some CVAR_ARCHIVE cvar was changed.
alias models do vertex blending on the gpu.
GL renderer now uses vao when available.

TODO: Windows Vista has condition variables as documented here:
http://msdn.microsoft.com/en-us/library/ms682052(VS.85).aspx
Note this uses Slim Reader/Writer locks (Vista+ exclusive)
or critical sections.
The condition variable implementation is based on the libSDL implementation.
This code could probably be made more efficient with the use of events or
different mechanisms but for now the main concern is a correct and
complete solution.
