* libguile/foreign-object.c: * libguile/foreign-object.h (scm_make_foreign_object_1) (scm_make_foreign_object_2, scm_make_foreign_object_3) (scm_make_foreign_object_n): Change to take void * arguments, and to add a comment to the header indicating that these are convenience constructors. * libguile/foreign-object.c: * libguile/foreign-object.h (scm_foreign_object_unsigned_ref) (scm_foreign_object_unsigned_set_x): New functions, equivalent to the old scm_foreign_object_ref and scm_foreign_object_set_x. * libguile/foreign-object.c: * libguile/foreign-object.h (scm_foreign_object_signed_ref) (scm_foreign_object_signed_set_x): New functions taking scm_t_signed_bits. * libguile/foreign-object.c: * libguile/foreign-object.h (scm_foreign_object_ref) (scm_foreign_object_set_x): New functions that take void*.
