foreign.h presents a more pointer-centric interface
* libguile/foreign.c: * libguile/foreign.h: Rework interface to be more pointer-centric. Details are: (SCM_FOREIGN_TYPE_STRUCT, SCM_FOREIGN_TYPE_POINTER): Removed; now the pointer in a foreign is first-class. If it points to a native type like uint32, then it still has a tag; but if it points to something else, like a struct or a pointer or something, then its type is VOID (i.e., void*). (SCM_FOREIGN_POINTER): Rename from SCM_FOREIGN_OBJECT. (SCM_FOREIGN_VALUE_REF, SCM_FOREIGN_VALUE_SET): Rename from SCM_FOREIGN_OBJECT_REF and SCM_FOREIGN_OBJECT_SET, to indicate that they only work with value types. (SCM_FOREIGN_HAS_FINALIZER): Reserve a bit to indicate if the foreign pointer in question has a finalizer registered. (SCM_FOREIGN_LEN): For void* pointers, optionally store the length in bytes of the associated memory region. (SCM_FOREIGN_VALUE_P): Rename from SCM_FOREIGN_SIMPLE_P. (SCM_VALIDATE_FOREIGN_VALUE): Rename from SCM_VALIDATE_FOREIGN_SIMPLE. (scm_take_foreign_pointer): Rename from scm_c_take_foreign. Remove scm_c_from_foreign. (scm_foreign_type): New accessor. (scm_foreign_ref, scm_foreign_set_x): Take some optional args, used when dereferencing void pointers. * libguile/dynl.h: * libguile/dynl.c (scm_dynamic_pointer): New function, used by scm_dynamic_func. Adapt code to foreign.h changes. * libguile/goops.c (scm_enable_primitive_generic_x) (scm_set_primitive_generic_x): Use the SCM_SET_SUBR_GENERIC macro. * libguile/gsubr.c (create_gsubr): Adapt to API change. * libguile/gsubr.h (SCM_SUBRF, SCM_SUBR_GENERIC): Store the pointer directly, not indirected. * libguile/snarf.h (SCM_DEFINE, SCM_IMMUTABLE_FOREIGN): Store subr pointers directly. Adapt to SCM_FOREIGN_TYPE_VOID change. * libguile/vm-i-system.c (subr-call): Access the void* directly.
