  Add cache busting to attribute cache This makes the git attributes and git ignores cache check stat information before using the file contents from the cache. For cached files from the index, it checks the SHA of the file instead. This should reduce the need to ever call `git_attr_cache_flush()` in most situations. This commit also fixes the `git_status_should_ignore` API to use the libgit2 standard parameter ordering.
