Introduce the function cmReadGccDepfile that parses a GCC-style depfile and returns its content. The implementation uses a lexer that is modeled after the re2c implementation in Ninja. The sample files of the autotest have been created with gcc 8.3.0. This depfile reader is to be used by the Autogen facility to make use of the depfiles that are generated by Qt's meta object compiler.
