* fileio.c (Finsert_file_contents):
Use bool for booleans.
* coding.h, lisp.h: Reflect above API changes.
* coding.c: Remove unnecessary static function decls.
(detect_coding): Use unsigned, not signed, to copy an unsigned field.
(decode_coding, encode_coding, decode_coding_gap): Return 'void',
not a boolean 'int', since callers never look at the return value.
(ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
* coding.h (decoding_buffer_size, encoding_buffer_size)
(emacs_mule_string_char): Remove unused extern decls.
(struct iso_2022_spec, struct coding_system):
Use 'unsigned int : 1' for boolean fields, since there's more than one.
(struct emacs_mule_spec): Remove unused field 'full_support'.
All initializations removed.
* cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
