Spoike c6c3d3f4e0 Trimmed some dead files. 
Quick hack preliminary d3d11 renderer. I'm not likely to touch this again for quite some time.
Sys_Error works properly on android, with an error message shown. Should be less of a stab in the dark if you get errors. Seg faults are still instantly fatal. Not much I can reliably do about those - most of the juicy ones will likely occur within the gl drivers (even if its my fault) and java will still call in to it.
Stereoscopic (quad-buffered) rendering is in the gl renderer. You'll likely need a quatro to use it despite it being a gl 1.0 feature. No idea about ati. See r_stereo_method for non-quad-buffered alternatives.
Tweaked networking to not overflow so much. Needs testing against other qw clients.
Fixed an issue with surface numbers > 32k on limit-breaking maps.
Fixed a preparse issue resulting in QW clients dying with the ne_ruins map's progs.
Support for the DP-variant of BSP2. The depricated RMQ variant is still supported.
QTV proxy now uses ipv6 hybrid sockets where possible. Preliminary pext support.
