Fix string-to-multibyte overlong sequence bug
* src/character.h (MULTIBYTE_LENGTH, MULTIBYTE_LENGTH_NO_CHECK):
Remove, replacing with ...
(multibyte_length): ... this new function. All callers changed.
The new function rejects overlong multibyte forms.
* test/src/buffer-tests.el (buffer-multibyte-overlong-sequences):
New test.
