* added API stub of static_filesystem * added callback functions * added basic directory listing * resize filesystem if necessary * added path stub * adds imlementation and tests of path * adds mock of wpf_request * adds test implementation and some matchers * added matcher of readdir results * fixes default directory test * adds implementation of static_filesystem_add and add_text * added implementation of read * adds implementation of filesystem_read * corrects naming of some functions * removes Flawfinder comments, since Flawfinder is disabled
