Currently, submodule-config.c doesn't have an externally accessible function to read gitmodules only if it wasn't already read. But this exact behavior is internally implemented by gitmodules_read_check(), to perform a lazy load. Let's merge this function with repo_read_gitmodules() adding a 'skip_if_read' which allows both internal and external callers to access this functionality. This simplifies a little the code. The added option will also be used in the following patch. Signed-off-by: Matheus Tavares <matheus.bernardino@usp.br> Signed-off-by: Junio C Hamano <gitster@pobox.com>

/**
 | 
						|
 * 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().
 | 
						|
