- fix inverted shift direction in MBL() and MBR() macro in BE case
(used by GETBITS() and PUTBITS() in copycols() function in rasops_bitops.h)
- make all bitmask values unsigned and use proper uint32_t types for
bitmap variables (to avoid arithmetic right shift)
- fix various botches in right-to-left copy op (logic is taken from hp300)
Tested on bwtwo(4) on NetBSD/sparc.
- Don't use int32_t/u_int32_t unless we must.
- Remove C++ single line comment delimeters that crept in.
- Remove defs pertaining to byte granularity 'ragged-edge' bitmasks.
- Move all declarations of per-depth initialization functions to rasops.h.
- Other minor cleanup.
