TIMBER!

Move the vcl_fetch{} execution up between fetching the headers and the
body of the backend response.

This makes obj.* unavailable in vcl_fetch{} and replaces it with a
new beresp.* family of variables.

This paves the way for a lot of good stuff, such as streaming pass,
on-the-fly delivery of misses, storage selection based on headers
etc.
