* font.c (Qiso8859_1, Qiso10646_1, Qunicode_bmp): Moved from

ftfont.c.
(font_unparse_xlfd): Fix argument type declaration.  Append "*" if
registry doesn't specify encoding part.
(font_find_for_lface): Pay attention to LFACE_FONT_INDEX.
(font_open_by_name): At first try parsing the name.
(syms_of_font): Declare Qiso8859_1, Qiso10646_1, and Qunicode_bmp
as Lisp symbols.
