Bill Currie 63e30e6ae0 [win] Fix a handful of small bugs for windows
Only 64-bit windows is tested, and there are still various failures, but
QF is limping along in windows again.

nq-sdl works for sw, and sw32, gl and glsl are mostly black (but not
entirely for gl?),  vulkan is not supported with sdl.

nq-win works for sw and sw32, and sort of for vulkan (very dark and
upside-down?). gl and glsl complain about vid mode,

qw-client-[sdl,win] seem to be the same, but something is wrong with the
console (reading keyboard input).
