The code to make "git grep" recurse into submodules has been

an alternate object store" mechanism (which is suboptimal).

submodule-config: pass repo upon blob config read
grep: add repository to OID grep sources
grep: allocate subrepos on heap

grep: use submodule-ODB-as-alternate lazy-addition
submodule: lazily add submodule ODBs as alternates

After "git clone --recurse-submodules", all submodules are cloned

"git rebase" by default skips changes that are equivalent to
commits that are already in the history the branch is rebased onto;

Starting in commit 0f533c7284 (pack-bitmap: read multi-pack bitmaps,
2021-08-31), we no longer look at the "struct bitmap_index" passed to
try_partial_reuse(). This is because we only handle verbatim reuse from
a single pack: either the pack whose bitmap we're looking at, or the
"preferred" pack of a midx bitmap. And thus the primary item we look at
is the "pack" parameter added by that same commit, and not the
bitmap_git->pack parameter (which would be NULL for a midx bitmap). It's
our caller, reuse_partial_packfile_from_bitmap(), which decides which
pack to use and passes it in to us.
Drop the unused parameter to prevent confusion.

We never look at the repository argument which is passed. This makes
sense, since the multi_pack_index struct already tells us everything we
need to access the files in its associated object directory.
