there is no assurance that just because the pack file lives in
objects/pack and doesn't end in .idx that we can read and decompress
its contents properly.

If we encounter what we think is a pack file and it isn't or we don't
recognize its version then die and suggest to the user that they
upgrade to a newer version of GIT which can handle that pack file.

There are already 3 other places where the pack header and version are 
validated: see git-grep pack_version_ok *.c output.  Maybe it would be 
best to abstract those tests all in one place.
