PF_VarString can now shortcircuit, directly returning the first argument (which also bypasses related length limitations). this required const correctness fixes. r_showshaders cvar reports the wall texture being pointed at. improve dp compat in a number of areas, should now mostly be able to run xonotic 0.8.2, but will need some more extra cvars/defaults/stuff. fix q3bsp loader race condition. fix dpm loader multi-surface issue. remove limit on stringbuffer count. don't poll xinput (because its disturbingly slow), instead wait for some window message before re-checking. fixed splitscreen saved games. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5140 fc73d0e0-1445-4013-8a0c-d673dee63da5
