Add --aggressive option to 'git gc'
This option causes 'git gc' to more aggressively optimize the repository at the cost of taking much more wall clock and CPU time. Today this option causes git-pack-objects to use --no-use-delta option, and it allows the --window parameter to be set via the gc.aggressiveWindow configuration parameter.
