Have content/ create and destroy its own threads.

Change embedding API and embedders to allow for this.

Push inheritance of base::Thread down to content::BrowserThreadImpl so
that content::BrowserThread is just a namespace for API functions.

This change temporarily disables chrome_frame_net_tests as agreed by the CF lead, see bug 105435.
