Remove obsolete pre-unicode2 macros.

* character.h (MULTIBYTE_FORM_LENGTH, PARSE_MULTIBYTE_SEQ): Remove.
* composite.c (composition_reseat_it):
* data.c (Faset):
* fns.c (Ffillarray):
* regex.c (re_search_2): Use BYTES_BY_CHAR_HEAD.
  [!emacs] (BYTES_BY_CHAR_HEAD): Define instead of MULTIBYTE_FORM_LENGTH.
