Subject: mkdeps.c, mkdeps.h: New files.

	* mkdeps.c, mkdeps.h: New files.
	* po/POTFILES.in: Add them.
	* Makefile.in (LIBCPP_OBJS): Add mkdeps.o.
	(cpplib.o, cppinit.o): Depend on mkdeps.h.
	(mkdeps.o): New target.

	* cppfiles.c: Delete deps_output.
	* cppinit.c: Include mkdeps.h.  Delete known_suffixes,
	OBJECT_SUFFIX, and base_name.
	(cpp_cleanup): Use deps_free.  Free ihash->name when clearing
	the include hash.
	(initialize_dependency_output): Use deps_init,
	deps_add_target, deps_calc_target, and deps_add_dep.  Remove
	all the unnecessary string bashing.
	(cpp_finish): Use deps_write.  Remove an unnecessary nesting
	level.
	* cpplib.c (do_include): Use deps_add_dep.
	* cpplib.h (struct cpp_reader): Replace deps_buffer,
	deps_allocated_size, deps_size, deps_column members with
	single pointer to a struct deps.  Delete prototype of
	deps_output.
