Introduce all the plumbing for Session Storage. This mostly consists of creating and tracking namespace ids in conjunction with the tabs. This is essentially just a bunch of dead code at the moment, but the next patch will get rid of the old way of generating/cloning IDs (initiated by the renderer) and instead use these IDs.

TEST=none
BUG=none
