linux: OOP windowed plugins

There are still a few issues, but that's a start.
- only windowed plugins
- we can't currently create the gtksocket in background tabs, because their gtkwidgets are not yet in the hierarchy, so they can't be realized (that's what gives the XID).
- the plugin process talks to the browser process through the renderer process to create/destroy the gtksockets, because the plugin doesn't know which renderer it's talking to. We need a bit more plumbing to be able to have direct IPC.
- some code is duplicated between chrome and test_shell. We should probably refactor it, but I'm not sure where the common part should live.

Patch from Antoine Labour <piman@google.com>, with some touchups by me.
