(struct ccl_program): Members eol_type and multibyte

deleted.  New members src_multibyte, dst_multibyte, consumed, and
produced.
(struct ccl_spec): Members decoder and encoder deleted.  New
memeber ccl.
(CODING_SPEC_CCL_PROGRAM): New macro.
(ccl_driver): Prototype updated.
(Qccl, Qcclp, Fccl_program_p): Extern them.
(CHECK_CCL_PROGRAM): New macro.
