PATCH 1/1 Create 'git gc' to perform common maintenance operations.

Junio asked for a 'git gc' utility which users can execute on a regular basis to perform basic repository actions such as:

* prune
* repack -a -d
* reflog expire
* rerere gc
* pack-refs --prune

So here is a command which does exactly that. The parameters fed to reflog's expire subcommand can be chosen by the user by setting configuration options in .git/config (or ~/.gitconfig), as users may want different expiration windows for each repository but shouldn't be bothered to remember what they are all of the time.

You should do "repack -a -d" _before_ pruning, because then pruning will be much more efficient (thanks to a more efficient repo format).
