Vim control lines were re-introduced or not entirely cleaned up. This nukes them again. Removing from embedding, extensions, gfx, hal, ipc, layout, mailnews, media and memory. More to come.

* OWNERSHIP MODEL
|
|
*
|
|
* Roughly speaking, the child side "actually owns" a Layer. This
|
|
* is because the parent side is the "shadow"; when the child
|
|
* releases a Layer, the parent's shadow is no longer meaningful.
|
|
*
|
|
* To implement this model, the concrete PLayerParent keeps a
|
|
* strong ref to its Layer, so the Layer's lifetime is bound to
|
|
* the PLayerParent's. Then, when the Layer's refcount hits 0 on
|
|
* the child side, we send __delete__() from the child to parent.
|
|
* The parent then releases its Layer, which results in the Layer
|
|
* being deleted "soon" (usually immediately).
