(scm_c_make_gsubr, scm_c_define_gsubr,
scm_c_make_gsubr_with_generic, scm_c_define_gsubr_with_generic): New functions. They replace scm_make_gsubr and scm_make_gsubr_with_generic. The `make' variants only create the gsubr object, while the `define' variants also put it into the current module. Changed all callers. (scm_make_gsubr, scm_make_gsubr_with_generic): Deprecated.
