Lots of GLchan datatype changes.

Added GLvector4us datatype in math/m_vector.[ch]
Added _math_trans_4us() in math/m_translate.[ch]
Choose GLvector4ub, GLvector4us, GLvector4f at compile time based on CHAN_BITS.
Made Driver.ClearColor() and Driver.ClearIndex() optional driver functions.
Changed args to Driver.ClearColor(), updated drivers.
Reordered files in Makefile.X11
