Subject: Test in git-init-db if the filemode can be trusted

... and if not, write an appropriate .git/config. Of course, that happens
only if no config file was yet created (by a template or a hook).

Subject: Create object subdirectories on demand (phase II)

This removes the unoptimization.  The previous round does not mind
missing fan-out directories, but still makes sure they exist, lest
older versions choke on a repository created/packed by it.

This round does not play that nicely anymore -- empty fan-out
directories are not created by init-db, and will stay removed by
prune-packed.  The prune command also removes empty fan-out directories.
