Refactor HttpURLConnection implementation.
Break HttpURLConnectionImpl into two parts: the part that
implements the Java API (that follows redirects etc.) and
the part that speaks HTTP. The HTTP part is called HttpEngine,
and it can only be used for a single HTTP request. This makes
it easier to set request properties that only apply to a
single socket request.
Tests for 'Vary', 'Content-Location' and warnings.
For simplicity of implementation I've chosen not to support
'Vary' at this time.
The 'Content-Location' header doesn't require any work from
the cache.
Warnings are ugly but allow the caller to identify when the
cache results may be problematic.
Also breaking HttpResponseCache's dependency on HttpURLConnectionImpl
so it can be tested on the RI.
