Xpra: Ticket #390: damage events for the posix shadow server

At the moment we use timer-based screenscraping, I believe we should be able to re-use the damage notification approach of the regular server.

And whilst we're at it:

low priority - re-scheduling

Shouldn't be too hard and could make a huge difference in usability, could also use #365

try to use x11 damage events with the shadow server

The patch above does not work... and on top of that, the few damage events it does receive show that we would often end up doing no better than we currently do with a timer!

Someone else may be interested in this in the future, re-scheduling.

Redundant: the proper way to deal with this is #1247.
