Added a version of takeRequest that takes a timeout.
Fix a bug where the cacheResponse's request method was wrong.

We were returning the message (like 'OK') rather than the method
(like 'GET'). Ugh.

Eagerly create Entry Files for every value.

Through the various code paths that an Entry would pass through both the clean and dirty File would be needed at least once. Creating it and the StringBuilders every time was having a large impact on allocation in high-frequency situations (like images in an Android app).
Fixes the do not follow redirects bug

The HttpEngine would not obey the set state because there was no
correlation between the HttpURLConnection.setInstanceFollowRedirects
method and the OkHttpClient.

Fixed the missing link by adding a new setFollowRedirects method to the
OkHttpClient class.  Bridged the gap for the HttpURLConnection.setInstanceFollowRedirects
by forwarding that state into the OkHttpClient.

Now the HttpEngine will always obey the OkHttpClient redirect state when
attempting the followUp phase.

Added necessary test to both OkUrlFactoryTest and CallTest.

Move connect to be closer to connection.

This eliminates some awkwardness in OkHttpClient, where it needs
to make a bunch of internal calls to Connection.
