Subject: [PATCH] Add flag `FT_CONFIG_OPTION_SVG`.

This flag is going to be used to conditionally compile support for OT-SVG
glyphs.  FreeType will do the parsing and rely on external hooks for
rendering of OT-SVG glyphs.

* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_SVG): New flag.
