Jeff King 73c3f0f704 index-pack: check .gitmodules files with --strict
Now that the internal fsck code has all of the plumbing we
need, we can start checking incoming .gitmodules files.
Naively, it seems like we would just need to add a call to
fsck_finish() after we've processed all of the objects. And
that would be enough to cover the initial test included
here. But there are two extra bits:

  1. We currently don't bother calling fsck_object() at all
     for blobs, since it has traditionally been a noop. We'd
     actually catch these blobs in fsck_finish() at the end,
     but it's more efficient to check them when we already
     have the object loaded in memory.

  2. The second pass done by fsck_finish() needs to access
     the objects, but we're actually indexing the pack in
     this process. In theory we could give the fsck code a
     special callback for accessing the in-pack data, but
     it's actually quite tricky:

       a. We don't have an internal efficient index mapping
	  oids to packfile offsets. We only generate it on
	  the fly as part of writing out the .idx file.

       b. We'd still have to reconstruct deltas, which means
          we'd basically have to replicate all of the
	  reading logic in packfile.c.

     Instead, let's avoid running fsck_finish() until after
     we've written out the .idx file, and then just add it
     to our internal packed_git list.

     This does mean that the objects are "in the repository"
     before we finish our fsck checks. But unpack-objects
     already exhibits this same behavior, and it's an
     acceptable tradeoff here for the same reason: the
     quarantine mechanism means that pushes will be
     fully protected.

In addition to a basic push test in t7415, we add a sneaky
pack that reverses the usual object order in the pack,
requiring that index-pack access the tree and blob during
the "finish" step.

This already works for unpack-objects (since it will have
written out loose objects), but we'll check it with this
sneaky pack for good measure.
