This is a further extension of Mark's variant Key header extensions to HTTP.

When I proposed adding support for the first steps of these extensions 
Alex complained that Squid's storage needed major overhaul before it was 
worth doing.



FYI; The "group" identifier in this HTTPbis Draft is akin to StoreID for 
a "Vary marker" store object.

To support this mechanism cleanly Squid should first refactor "Vary 
marker" to to have multiple headers determining further lookups objects, 
not just the one Vary pattern.

That is similar matching logic needed for the prior Key (also Vary-Key) 
header mechanism which Alex has already vetoed as "too complex" to 
implement.
