Fixed openal linux .so name, now usable in linux. sdl audio code now uses sdl2 audio, and thus can support multiple devices simultaneously. linux non-sdl builds now dynamically link to SDL2 for audio. This is now the default audio system in ALL non-android linux builds. This is the only real option to cope with the mess that is alsa. Fix netgraph when running q2. No longer makes palette assumptions. Fixed q2 ping values. Tweaked a load of windows code to use wide chars, because microsoft do not support utf-8. fixed an issue with winsspi where data from large packets could get lost. now tries to read .lit2 files (although still refuses to read them for now). Fixed motionblur. To make Shpuld happy... :P git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4871 fc73d0e0-1445-4013-8a0c-d673dee63da5
