[Chromoting] Initial plumbing for cursor shape.

This cl contains:
* protocol for sending cursor shape on control channel from host to client
* cross-platform (Pepper) client code for rendering host cursor
* Linux host support for reading current cursor shape

Separate CLs will follow with Mac and Windows host support.
