Fix crashing bug in use of bold fonts from x-select-font on W32.

* w32font.c (w32_to_fc_weight): New function.
(w32font_full_name, logfont_to_fcname): Use it.

* font.h (font_style_symbolic_from_value): Remove.

* font.c (font_style_symbolic_from_value): Remove.
(font_style_symbolic): Revert to pre 2008-06-13 version.
