(Qget_emacs_mule_file_char, Qload_force_doc_strings,
load_each_byte, unread_char): New variables.
(readchar_backlog): This variable deleted.
(readchar): Return a character unless load_each_byte is nonzero.
Handle the case that readcharfun is Qget_emacs_mule_file_char or a
cons.  If unread_char is not -1, simply return it.
(unreadchar): Handle the case that readcharfun is
Qget_emacs_mule_file_char or a cons.  Set unread_char if
necessary.
(read_multibyte): This function deleted.
(readbyte_for_lambda, readbyte_from_file, readbyte_from_string)
(read_emacs_mule_char): New functions.
(Fload): Even if the file doesn't have the extention ".elc", if
safe_to_load_p returns a positive version number, assume that the
file contains bytecompiled code.  If the version is less than 22,
load the file while decoding multibyte sequences by emacs-mule.
(readevalloop): Don't use readchar_backlog.
(Fread): Likewise.  Pay attention to the case that STREAM is a
cons.
(Fread_from_string): Pay attention to the case that STREAM is a
cons.
(read_escape): The arg BYTEREP deleted.
(read1): Set load_each_byte to 1 temporarily while handling
#@NUMBER.  Don't call read_multibyte.
(read_vector): Call Fread with a cons.  If readcharfun is
Qget_emacs_mule_file_char, decode the read string by emacs-mule.
(read_list): If doc_reference is 2, make the cdr part string as
unibyte.
(syms_of_lread): Intern and staticpro Qget_emacs_mule_file_char
and Qload_force_doc_strings.
