[PATCH/RFC 3/3] git-gui: Do not suggest a gc if gc --auto would not do it

In particular, if the user has set gc.auto to 0 or some other value, respect that setting.

The gui-specific heuristic of assuming Windows filesystems will tolerate fewer loose objects has been carried over.

This patch vastly increases the loose object count threshold for a sort of compatibility with the console-based git programs. The ideal threshold may be different since the user can easily turn down an offer to gc. But for now, let us assume that a number of loose objects that is tolerable when working from the command line will also be tolerable in the gui.

Unfortunately, this duplicates code from builtin-gc.c. A proper fix would be involve teaching gc to cooperate with the gui more closely.
