Create initial GPU backing store in the GPU process for X windows applications.

This gets the window from the RenderWidgetHostViewGtk and just does OpenGL
calls directly into it. There are a lot of bugs, especially around expose
events, which aren't really processed at all, and also tab teardown and
reparenting.

The new backing store defaults to off.

This does some refactoring of the existing Windows GPU process backing store
implementation to make some of it sharable by this Linux verion.

This removes some previously defunct in-process GL backing store code and moves
it to the GPU process.

This patch does some refactoring around how child processes are created using
zygoes or not. I found there were many places where a command line would be
checked with special logic to know whether to enable zygote code or not. I
tried to unify this so it could be computed once for each process type. This is
what most of the changed files in chrome/browser are related to.
