This topic was born out of tb/pseudo-merge-bitmaps, which has a few
quality-of-life improvements in the pack-bitmap machinery.

The main changes are to remove the static 'struct bitmap_writer', drop
one unused fields, and start using another unused one (see "move
commit_positions into commit_pos fields").

There are other smaller changes, too, like cleaning up the flag
allocation table in object.h, as well as introducing a new
bitmap_writer_free() function.

The next round of tb/pseudo-merge-bitmaps will be based on this branch.

Thanks in advance for your review!
