  Adding git_config_foreach_match() iteration fn Adding a new config iteration function that let's you iterate over just the config entries that match a particular regular expression. The old foreach becomes a simple use of this with an empty pattern. This also fixes an apparent bug in the existing `git_config_foreach` where returning a non-zero value from the iteration callback was not correctly aborting the iteration and the returned value was not being propogated back to the caller of foreach. Added to tests to cover all these changes.
