* cairo/*: merge changes to Mono.Cairo since we split back in Oct 2008. Not much changed. Scrubbed the doc index and updated NativeMethods to match. Commented with DONTCARE the ones we will ignore. Implemented a few of them, including an initial Device binding. Still some work to do, and some discovery to be done to see what happened to Xcb, Glitz, and DirectFB surfaces and whether we need to remove those classes.
