Junio C Hamano f3bf922409 [PATCH] verify-pack updates.
Nico pointed out that having verify_pack.c and verify-pack.c was
confusing.  Rename verify_pack.c to pack-check.c as suggested,
and enhances the verification done quite a bit.

 - Built-in sha1_file unpacking knows that a base object of a
   deltified object _must_ be in the same pack, and takes
   advantage of that fact.

 - Earlier verify-pack command only checked the SHA1 sum for the
   entire pack file and did not look into its contents.  It now
   checks everything idx file claims to have unpacks correctly.

 - It now has a hook to give more detailed information for
   objects contained in the pack under -v flag.

Junio C Hamano f9253394a2 [PATCH] Add git-verify-pack command.
Given a list of <pack>.idx files, this command validates the
index file and the corresponding .pack file for consistency.

This patch also uses the same validation mechanism in fsck-cache
when the --full flag is used.

During normal operation, sha1_file.c verifies that a given .idx
file matches the .pack file by comparing the SHA1 checksum
stored in .idx file and .pack file as a minimum sanity check.
We may further want to check the pack signature and version when
we map the pack, but that would be a separate patch.

Earlier, errors to map a pack file was not flagged fatal but led
to a random fatal error later.  This version explicitly die()s
when such an error is detected.

Linus Torvalds 01247d8742 Make git pack files use little-endian size encoding
This makes it match the new delta encoding, and admittedly makes the
code easier to follow.

This also updates the PACK file version to 2, since this (and the delta
encoding change in the previous commit) are incompatible with the old
format.

Linus Torvalds a733cb606f Change pack file format. Hopefully for the last time.
This also adds a header with a signature, version info, and the number
of objects to the pack file.  It also encodes the file length and type
more efficiently.
