A function that runs a hook is used in several Git commands.
builtin-commit.c has the one that is most general for cases without
piping. The one in builtin-gc.c prints some useful warnings.
This patch moves a merged version of these variants into libgit and
lets the other builtins use this libified run_hook().
The run_hook() function used in receive-pack.c feeds the standard
input of the pre-receive or post-receive hooks. This function is
renamed to run_receive_hook() because the libified run_hook() cannot
handle this.

A quick comparison to v1:
- builtin-checkout.c/post_checkout_hook() makes use of
run_hook() now.
- The lost warnings Dscho pointed at are in the libified
run_hook() now.
