Output unquoted family name as a series of identifiers
It tries to serialize unquoted family names as a series of identifiers. For family names which contain special white spaces like leading white space, trailing white space, and consective white spaces, unquoted names are marked quoted in parsing to avoid complicating serialization code.
This fixes [bug 1434802](https://bugzilla.mozilla.org/show_bug.cgi?id=1434802).

style: Use more CascadeData and less Stylist for XBL stuff.
Just some more use-cases that can be converted right away.
I'm trying to make XBL not use a whole Stylist, slowly...

style: Handle quirks-mode changes correctly.
The reason why bug 1355721 regressed this is because in non-e10s we definitely
flush before parsing the standards quirks-mode. And bug 1355721 introduced an
unconditional UpdateStylistIfNeeded, unless the counter style / font
equivalents.
That means that the stylist wouldn't remain on its initial state after the first
flush, which itself means that when the compat mode changed, the UA and user
rules were already on the stylist with the quirks mode keys. That makes
class-names be keyed in ascii lowercase.
After that no user style changed, so no rebuild happens for the cascade data in
the user origin, so we keep looking at the wrong keys indefinitely.
We should try to avoid the flush there and ensure that by the time we create a
pres shell the quirks mode is already up-to-date...

Remove reference to the Gecko pref svg.paint-order.enabled
<!-- Please describe your changes on the following line: -->
This pref (to potentially disable support for a CSS property) is to be removed from Gecko, so we should also remove the reference to it in the Servo (stylo) code; the property will be always-supported, just like the majority of others.
