with the last arg charset_list acquired from coding.
(Fdefine_coding_system_internal): For ccl-based coding system, fix
the attribute coding_attr_ccl_valids.
(ccl_driver): New arg CHARSET_LIST. Use the above macros instead
of DECODE_CAHR, ENCODE_CHAR, CHAR_CHARSET.
(Fccl_execute): Call ccl_driver with the last arg Qnil.
(Fccl_execute_on_string): Likewise.
unicode fonts for ASCII characters.
(x-decompose-font-name): Don't try to resolve PATTERN by
x-resolve-font-name.
(x-complement-fontset-spec): Never prepend an ASCII font.
(create-fontset-from-fontset-spec): If a fontset of the same name
already exists, override it instead of signalling an error. Don't
turn `ascii' into `latin'. Don't update fontset-alias-alist here.
function.
(print-fontset): Use print-fontset-element to print the elements
of a fontset. Use it also to print fonts fallen back to the
default fontsets.

(FONTSET_FALLBACK): New macro.
(fontset_face): Try also the default fontset.
(make_fontset): Realize a fallback fontset from the default
fontset.
(generate_ascii_font_name): Moved from xfaces.c. Rewritten by
using split_font_name_into_vector and build_font_name_from_vector.
(Fset_fontset_font): Access the elements of font_spec by enum
FONT_SPEC_INDEX. If font_spec is a string, extract the registry
name by using split_font_name_into_vector.
(Fnew_fontset): If no ASCII font is specified in FONTLIST,
generate a proper font name from the fontset name. Update
Vfontset_alias_alist.
(n_auto_fontsets): New variable.
(new_fontset_from_font_name): New function.
(Ffont_info): Store the information about fonts generated from the
default fontset in the first extra slot of the returned
char-table.
(font_name_registry): Function deleted.
(split_font_name_into_vector): New function.
(build_font_name_from_vector): New function.
(font_list): The argument REGISTRY is now a list of registry
names.
(choose_face_font): If we are choosing an ASCII font, and ATTRS
specifies an explicit font name, return the name as is. Make a
list of registy names.
Use coding-system-type, coding-system-charset-list.
(standard-keyboard-coding-systems): Deleted.
(set-locale-environment): Maybe set keyboard coding system. Avoid
typical warning about codeset in C locale.

(detect_coding_emacs_mule, detect_coding_iso_2022)
(detect_coding_sjis, detect_coding_big5)
(detect_coding_ccl, detect_coding_charset): Change argument MASK
to DETECT_INFO. Update DETECT_INFO and return 1 if the byte
sequence is valid in this coding system. Callers changed.
(MAX_ANNOTATION_LENGTH): New macro.
(ADD_ANNOTATION_DATA): New macro.
(ADD_COMPOSITION_DATA): Argument changed. Callers changed. Call
ADD_ANNOTATION_DATA. The format of annotation data changed.
(ADD_CHARSET_DATA): New macro.
(emacs_mule_char): New argument ID. Callers changed.
(decode_coding_emacs_mule, decode_coding_iso_2022)
(decode_coding_sjis, decode_coding_big5, decode_coding_charset):
Produce charset annotation data in coding->charbuf.
(encode_coding_emacs_mule, encode_coding_iso_2022): Pay attention
to charset annotation data in coding->charbuf.
(setup_coding_system): Add CODING_ANNOTATE_CHARSET_MASK
coding->common_flags if the coding system is iso-2022 based and
uses designation.
(produce_composition): Adjusted for the new annotation data
format.
(produce_charset): New function.
(produce_annotation): Handle charset annotation.
(handle_composition_annotation, handle_charset_annotation): New
functions.
(consume_chars): Handle charset annotation. Utilize the above two
functions.
(encode_coding_object): If SRC_OBJECT and DST_OBJECT are the same
buffer, get the deleted text as a string and set
coding->src_object to that string.
(detect_coding, detect_coding_system): Use the new struct
coding_detection_info.
