Evas font+textblock: Stopped using FcNameParse, parse ourselves.

FcNameParse is pretty bad, not only that it's pretty bad, it doesn't
work well in some cases. Also this makes our lives a lot easier since
we want to allow overriding style/weight/width and etc from markup.
We now parse the "font" markup ourselves, populating a font description
structure that we created, and then override values in it as needed.
