            rasops_masks.h

Log Message:
Fix 1 bpp rasops copycols() op:

 - 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.
