* Makefile.in (tradcpp0): Depend on mkdeps.h. Link mkdeps.o

        * cppinit.c (cpp_start_read): Update comment, remove unneeded
        if statement.
        * tradcpp.c: Include mkdeps.h.
        (deps, print_deps_phony_targets, deps_append, output_deps,
        init_dependency_output, output_deps): New.
        (deps_buffer, deps_allocated_size, deps_size, deps_column,
        deps_output): Delete.
        (print_deps_missing_files): Rename deps_missing_files.
        (inhibit_output): Make global.
        (main): Delete inhibit_output, deps_stream, deps_target.
        Use mkdeps functionality in the same way as cpplib.  Remove
        -g3 handling.  Handle -MF, -MP, -MQ, -MT.  Update handling of
        -M and -MM.  Remove old handling of deps via deps_out, and
        old reading of environment variables.
        (get_filename): Update to use deps_add_dep.
