The new logic is as follows:
* Given a URL to insert into url(), check that it is properly URL
encoded (in particular, a doublequote and backslash never occurs
within it) and then place it as url("http://example.com").
* Given a font name, if it is strictly alphanumeric, it is safe to omit
quotes. Otherwise, wrap in double quotes and replace '"' with '\22 '
(note trailing space) and '\' with '\5C ' (ditto).
We introduce expandCSSEscape() which is a hack for common parsing
idioms in CSS; this means that CSS escapes are now recognized inside
URLs as well as unquoted font names.

- Improve parseCDATA algorithm to take into account newline normalization
- Fix regression in FontFamily validator. We now have a legit parser in place, albeit somewhat limited in use. Will be superseded by parser for entire grammar
- Convert EncoderTest to new format
