largefiles: stat all largefiles in one batch before downloading

This avoids a lot of expensive roundtrips to remote repositories ... but might
be slightly slower for local operations.

This will also change some aborts on missing files to warnings. That will in
some situations make it possible to continue working on a repository with
missing largefiles.
