8c681e07c9 pack-redundant.c: learn about index v2
Initially the conversion was made using nth_packed_object_sha1() which
made this file completely index version agnostic. Unfortunately the
overhead was quite significant so I went back to raw index walking but
with selectable base and step values which brought back similar
performances as the original.

4287307833 [PATCH] clean up pack index handling a bit
Especially with the new index format to come, it is more appropriate
to encapsulate more into check_packed_git_idx() and assume less of the
index format in struct packed_git.

To that effect, the index_base is renamed to index_data with void * type
so it is not used directly but other pointers initialized with it. This
allows for a couple pointer cast removal, as well as providing a better
generic name to grep for when adding support for new index versions or
formats.

And index_data is declared const too while at it.

c4001d92be Use off_t when we really mean a file offset.
Not all platforms have declared 'unsigned long' to be a 64 bit value,
but we want to support a 64 bit packfile (or close enough anyway)
in the near future as some projects are getting large enough that
their packed size exceeds 4 GiB.

By using off_t, the POSIX type that is declared to mean an offset
within a file, we support whatever maximum file size the underlying
operating system will handle.  For most modern systems this is up
around 2^60 or higher.

a89fccd281 Do not use memcmp(sha1_1, sha1_2, 20) with hardcoded length.
Introduces global inline:

	hashcmp(const unsigned char *sha1, const unsigned char *sha2)

Uses memcmp for comparison and returns the result based on the length of
the hash name (a future runtime decision).

6d016c9c7f git-pack-redundant: speed and memory usage improvements

Not computing the pack_list permutaions all at once reduces memory

b99a394cd1 pack-redundant: type cleanups.
Binary representation of object names are unsigned char[20], not
signed.  Also verbose output had %lu format printing size_t
without (unsigned long) cast other places already had, so match
that.  Using format %zu was suggested but might not be supported
as widely.

Noted by Morten Welinder, fixed with input from H. Peter Anvin
and Hideaki Yoshifuji.
