This works for everything except the CCLayerTree* tests, which are all of the
interesting threading ones.  Something in the changes I've made there @#$*(
several of those up pretty good - lots of failures and timeouts.  The rest work,
however.

This patch really highlights how we need to have more of the
setup/initialization code inside CC, instead of being in WebCompositorImpl.

Tests all pass for me now.  Main issue were implementing
WebKit::Platform::currentThread() and WebKit::Platform::createThread() correctly
and making sure we aren't relying on WTF::MainThread anywhere since WTF
threading isn't initialized in our unit tests.

(clobber build).
It's a second try, previously, steps "compile, build" failed.
