479678 - Support HTTP/1.1 Upgrade in HttpClient 

+ Adding Connection.UpgradeFrom support to HttpConnectionOverHTTP
+ (Soft) Closing HttpConnectionOverHTTP on upgrade
+ Removing 'extends Connection' from Connection.UpgradeFrom and
  Connection.UpgradeTo to allow for use from components that
  delegate bytebuffer handling away from raw Connection
