bytevectors have internal parent field
* libguile/bytevectors.h (SCM_BYTEVECTOR_HEADER_SIZE): Bump, giving bytevectors another word: a parent pointer. Will allow for sub-bytevectors and efficient mmap bindings. * libguile/bytevectors.c (make_bytevector): (make_bytevector_from_buffer): Init parent to #f. (scm_c_take_bytevector, scm_c_take_typed_bytevector): Another argument, the parent, which gets set in the bytevector. * libguile/foreign.c (scm_pointer_to_bytevector): Use the parent field instead of registering a weak reference from bytevector to foreign pointer. * libguile/objcodes.c (scm_objcode_to_bytecode): Use the parent field to avoid copying the objcode. * libguile/srfi-4.c (DEFINE_SRFI_4_C_FUNCS): * libguile/strings.c (scm_from_stringn): * libguile/vm.c (really_make_boot_program): * libguile/r6rs-ports.c (scm_get_bytevector_some) (scm_get_bytevector_all, bytevector_output_port_procedure): Set the parent to #f.
