fix error paths wrt sync drivers, take 2
synchronous error codes which are passed through callbacks aren't a particularly good idea, after all: latest when the callback does stuff which does not concern the caller, the return code becomes ambiguous. instead, protect the sync_vars object with a refcount when invoking driver functions from loops, as the callbacks they call could invalidate the object and we would have no way of knowing that the loop should be aborted prematurely. the upcoming async imap driver will also need a refcount to protect the cancelation marker of the imap socket dispatcher loop.
