(coding_category_name): Include "coding-category-ccl".
(detect_coding_ccl): New function.
(setup_coding_system): Setup coding->spec.ccl.valid_codes from the
coding system priority `valid-codes' for CCL based coding systesm.
(detect_coding_mask): Check also a CCL based coding system.
(Fupdate_coding_systems_internal): Renamed from
Fupdate_iso_coding_systems.
(syms_of_coding): Change property char-table-extra-slot of
translation-table to 1. Initialize and static pro Qvalid_codes.
line endings. Always update dst_bytes to number of bytes actually copied.
(decode_eol): Fix value of coding->produced when decoding Unix
line endings (in case this function is ever used for that).
(detect_coding_mask): Skip ASCII codes at the head according to
ascii_skip_code.
(coding_priorities): New variable.
(Fset_coding_priority_internal): New function.
(detect_coding): Call set_coding_mask with coding_priorities as
arg CODING.
(init_coding_once): Initialize ascii_skip_code.
(syms_of_coding): Declare set-coding-priority-internal as a Lisp
function.
translate/translation respectively throughtout the file.
(encode_coding_iso2022): Fix bug in encoding a text ending by a
composite character.
(check_composing_code): If we are decoding the last block of data,
return 0 even if the source doesn't end by an escape sequence
which terminates the current composing sequence.
(decode_coding_iso2022): Decode correctly even if the source
doesn't end by an escape sequence which terminates the current
composing sequence.
if preceded by CR, since that confuses eol decoding.
(code_convert_region): When conversion fails with
CODING_FINISH_INSUFFICIENT_SRC, was overwriting src with garbage
from dst instead of copying from src to dst.
at the head and tail of conversion region correctly when adjusting
position keepers. Call adjust_after_insert to record undo info
and adjust markers when we don't have to change byte sequence of
a buffer.

encode_coding_sjis_big5, decode_eol, encode_eol, decode_coding,
encode_coding): Likewise.
(shrink_decoding_region, shrink_encoding_region): Do not skip
non-ASCII code in any cases. Bug fix for getting starting address
from BEG.
(code_convert_region): Sync character positions correctly by
paying attention to coding->fake_multibyte.
(code_convert_string): Set number of character and bytes just
processed in members of CODING.
(code_convert_string): Adjusted for the change of
code_convert_region.
(code_convert_region1): Likewise.
