bitmap.h: Add dump_bitmap...
2001-06-16 Daniel Berlin <dan@cgsoftware.com>
* bitmap.h: Add dump_bitmap, bitmap_zero, bitmap_union_of_diffs,
bitmap_a_or_b, bitmap_a_and_b, bitmap_first_set_bit,
bitmap_last_set_bit. All for compatibility with sbitmap's.
*bitmap.c (bitmap_zero): New function.
(bitmap_union_of_diffs): New function.
(bitmap_first_set_bit): New function.
(bitmap_last_set_bit): New function.
