/**
* The submodule config cache API allows to read submodule
* configurations/information from specified revisions. Internally
* information is lazily read into a cache that is used to avoid
* unnecessary parsing of the same .gitmodules files. Lookups can be done by
* submodule path or name.
*
* Usage
* -----
*
* The caller can look up information about submodules by using the
* `submodule_from_path()` or `submodule_from_name()` functions. They return
* a `struct submodule` which contains the values. The API automatically
* initializes and allocates the needed infrastructure on-demand. If the
* caller does only want to lookup values from revisions the initialization
* can be skipped.
*
* If the internal cache might grow too big or when the caller is done with
* the API, all internally cached values can be freed with submodule_free().
