In preparation for a larger change (D14162), some BLI_bitmap
functionality that could be submitted separately:
- Ability to declare a fixed size bitmap by-value, without extra
memory allocation: BLI_BITMAP_DECLARE
- Function to find the index of lowest unset bit:
BLI_bitmap_find_first_unset
- Test coverage of the above.
