The pack-bitmap machinery uses a structure called 'bitmap_writer' to collect the data necessary to write out .bitmap files. Since its introduction in 7cc8f971085 (pack-objects: implement bitmap writing, 2013-12-21), there has been a single static bitmap_writer structure, which is responsible for all bitmap writing-related operations.
In practice, this is OK, since we are only ever writing a single .bitmap file in a single process (e.g., `git multi-pack-index write --bitmap`, `git pack-objects --write-bitmap-index`, `git repack -b`, etc.).
However, having a single static variable makes issues like data ownership unclear, when to free variables, what has/hasn't been initialized unclear.
Refactor this code to be written in terms of a given bitmap_writer structure instead of relying on a static global.
Note that this exposes the structure definition of the bitmap_writer at the pack-bitmap.h level. We could work around this by, e.g., forcing callers to declare their writers as:
struct bitmap_writer *writer;
bitmap_writer_init(&bitmap_writer);and then declaring `bitmap_writer_init()` as taking in a double-pointer like so:
void bitmap_writer_init(struct bitmap_writer **writer);
which would avoid us having to expose the definition of the structure itself. This patch takes a different approach, since future patches (like for the ongoing pseudo-merge bitmaps work) will want to modify the innards of this structure (in the previous example, via pseudo-merge.c).
