Subject: [PATCH] Add parse types for CSS properties so we don't parse them in
 one huge switch.  (Bug 636029)  r=bzbarsky

With this patch, every CSS property is required to have one of the parse
type values (CSS_PROPERTY_PARSE_{FUNCTION,VALUE,INACCESSIBLE}) in its
flag bits.  This avoids needing a switch in
CSSParserImpl::ParseProperty(nsCSSProperty).

Note that this reserves more space in CSS_PROPERTY_PARSE_PROPERTY_MASK
than appears to be necessary; that space will be used in a later patch
in this series.
