CocoaSPDY v1.2

Improved metadata and critical session bug fixes

This release fixes 2 critical bugs in SPDYSessionManager that were released in v1.1. They fix a potential infinite loop of creating connections when starting the app on cellular, and another when an already-established connection terminates.

In addition to several minor internal fixes, there are two that impact the public API:

SPDYMetadata has been substantially expanded to include detailed stream timings. It is also now exposed via a concrete class implementation rather than a dictionary with documented keys. The dictionary-based version has been removed and is a breaking change for any consumers.

If the app is using NSURLSession instead of NSURLConnection, then it should implement the new SPDYURLSessionDelegate in order to better integrate with the configuration and queues provided by NSURLSession. This is especially true if custom cookie behavior is desired. In addition, by implementing this delegate, access to SPDYContext is provided, which provides a more definitive means of retrieving the metadata.

Changes included in v1.1:
