[WIP 0/2] Modifying pack-objects to support --blob-size-limit

[Jonathan Tan <jonathantanmy@google.com>]

I took a look at modifying builtin/pack-objects.c to support excluding
oversized blobs and reporting the exclusions that it has performed.
Here's a work in progress - it might be of aid to others who are working
on a similar feature and/or are modifying pack-objects for something
else.

The way I used to obtain a blob's size seems inefficient and redundant
with check_object() - if you have a suggestion to improve this, I'm
interested.

This is similar to [1] except that this reports blobs and their sizes
(after the packfile is printed), and is slightly more comprehensive in
that the read_object_list_from_stdin() codepath is also covered in
addition to the get_object_list() codepath. (Although, to be clear,
upload-pack always passes "--revs" and thus only needs the
get_object_list() codepath).
