Store peeled refs in packed-refs (take 2).
This fixes the previous implementation which failed to optimize
repositories with tons of lightweight tags. The updated
packed-refs format begins with "# packed-refs with:" line that
lists the kind of extended data the file records. Currently,
there is only one such extension defined, "peeled". This stores
the "peeled tag" on a line that immediately follows a line for a
tag object itself in the format "^<sha-1>".
The header line itself and any extended data are ignored by
older implementation, so packed-refs file generated with this
version can still be used by older git. packed-refs made by
older git can of course be used with this version.
