Edward Z. Yang d3abcb90e3 Rewrite CSS url() and font-family output logic.
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.
