Subject: [PATCH] (get_byte_table): New prototype [moved from chartab.c].
 (put_byte_table): Likewise [moved from chartab.c].
 (put_char_id_table_0): New inline function [moved from
 chartab.c]. (struct Lisp_Char_Table_Entry): Don't define in
 XEmacs UTF-2000. (Lisp_Char_Table_Entry): Likewise.
 (char_table_entry): Likewise. (XCHAR_TABLE_ENTRY):
 Likewise. (XSETCHAR_TABLE_ENTRY): Likewise.
 (CHAR_TABLE_ENTRYP): Likewise. (CHECK_CHAR_TABLE_ENTRY):
 Likewise. (NUM_ASCII_CHARS): Likewise. (struct
 Lisp_Char_Table): New implementation in XEmacs UTF-2000.
 (CHAR_TABLE_VALUE_UNSAFE): Likewise.
