Update testsuite with storagedriver interface changes
This change updates the testsuite to migrate to the new driver interface. This includes the new Stat call, changes to int64 over uint64 and the changes to the WriteStream signature. Several test cases have been added to vet implementations against various assumptions.pull/4/head
