In preparation for implementing a higher-level Rust API for accessing
Git configs, export some of the upstream configset API via libgitpub and
libgit-sys. Since this will be exercised as part of the higher-level API
in the next commit, no tests have been added for libgit-sys.
While we're at it, add git_configset_alloc() and git_configset_free()
functions in libgitpub so that callers can manage config_set structs on
the heap. This also allows non-C external consumers to treat config_sets
as opaque structs.
