gc: config option for running --auto in background

`gc --auto` takes time and can block the user temporarily (but not any
less annoyingly). Make it run in background on systems that support
it. The only thing lost with running in background is printouts. But
gc output is not really interesting. You can keep it in foreground by
changing gc.autodetach.

Running `git pack-refs` in a repository renders it
unclonable by Git versions prior to 1.5.1.2 over dumb
