Support SPDY in TBB Alpha

This primarily involves disabling the SPDY state storage and ensuring its connections are properly closed on New Identity.

We may also want to limit keepalive duration to 20 seconds, unless the spdy keepalive duration is also governed by the HTTP keepalive parameter in Firefox.

See #4603 (closed) for codepaths that are probably close to the spdy keepalive codepaths.

Trac:
Type: defect to enhancement

SPDY just underwent a couple protocol revisions. Firefox 15 now supports "SPDY v3"

We should verify nothing evil was added and see if it gives us more opportunity for non-determinism for website traffic fingerprinting. In particular, there's now flow control stuff to play with in v3.
