make alias lookup a public, procedural function
This converts git_config_alias to the public alias_lookup function. Because of the nature of our config parser, we still have to rely on setting static data. However, that interface is wrapped so that you can just say value = alias_lookup(key); Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
