(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.
