Boris Zbarsky 19251f27ce Bug 1562680. Implement the new syntax for Web IDL dictionary defaulting. r=peterv
`= {}` can now be used to indicate that an optional dictionary should have the
default value of 'default-initialized dictionary'

* to a string indicating the manner in which the popup should be anchored.
* Possible values for position are:
* before_start, before_end, after_start, after_end,
* start_before, start_after, end_before, end_after,
* overlap, after_pointer
*
* The anchor node does not need to be in the same document as the popup.

* If the attributesOverride argument is true, the popupanchor, popupalign
* and position attributes on the popup node override the position value
* argument. If attributesOverride is false, the attributes are only used
* if position is empty.
*
* For an anchored popup, the x and y arguments may be used to offset the
* popup from its anchored position by some distance, measured in CSS pixels.
* x increases to the right and y increases down. Negative values may also
* be used to move to the left and upwards respectively.
*
* Unanchored popups may be created by supplying null as the anchor node.
* An unanchored popup appears at the position specified by x and y,
* relative to the viewport of the document containing the popup node. In
* this case, position and attributesOverride are ignored.
