Johannes Schindelin 41f1a8e6a4 pack-mtimes: avoid closing a bogus file descriptor
In 94cd775a6c (pack-mtimes: support reading .mtimes files,
2022-05-20), code was added to close the file descriptor corresponding
to the mtimes file.

However, it is possible that opening that file failed, in which case we
are closing a file descriptor with the value `-1`. Let's guard that
`close()` call.

Reported by Coverity.

Taylor Blau 94cd775a6c pack-mtimes: support reading .mtimes files
To store the individual mtimes of objects in a cruft pack, introduce a
new `.mtimes` format that can optionally accompany a single pack in the
repository.

The format is defined in Documentation/technical/pack-format.txt, and
stores a 4-byte network order timestamp for each object in name (index)
order.

This patch prepares for cruft packs by defining the `.mtimes` format,
and introducing a basic API that callers can use to read out individual
mtimes.
