  config_parse: provide parser init and dispose functions Right now, all configuration file backends are expected to directly mess with the configuration parser's internals in order to set it up. Let's avoid doing that by implementing both a `git_config_parser_init` and `git_config_parser_dispose` function to clearly define the interface between configuration backends and the parser. Ideally, we would make the `git_config_parser` structure definition private to its implementation. But as that would require an additional memory allocation that was not required before we just live with it being visible to others.
