Brendan Dahl 133e16ecf4 Bug 1449791 - Remove platform support of overlays. r=bz
The following was removed:
- the main meat of the overlays and interface in XULDocument
- all overlay observers and forward references
- the notion of a master document
- XUL overlay provider
- manifest parsing of overlay attribute
- references to "overlay" atom
- restrictions on persistence (only need because of overlays)
- unused code that the above referenced

I also attempted to update comments that referenced overlays, but there is still
some work to be done here.
