Chris Lord b6dedb7d38 Bug 716403 - Annotate layers with the fixed margins from the PresShell. r=nrc,roc 
This annotates fixed layers with the margins that have been applied from
nsIPresShell->GetContentDocumentFixedPositionMargins. Using SyncViewportInfo
in CompositorParent, this allows for async fixed position margin setting.

* Generic enum serializer.

* The serializer would check value againts a range specified by

* For example, following is definition of serializer for enum type FOO.

*
* template <>
* struct ParamTraits<FOO>:
