syncbase: Prevent returned errors from leaking existence.

All client-to-Syncbase methods (db/cx/row, syncgroup manager, blob, cr)
have been sanitized to return ErrNoExistOrNoAccess when the caller has
no permission to know about the existence of an object.

GetDeltas and JoinSyncgroupAtAdmin have also been sanitized (GetDeltas
returns ErrDbOffline instead). PublishSyncgroup cannot be sanitized
until authentication is added to it.

Tests in subsequent CL.

This repository contains a reference implementation of the Vanadium APIs.

Unlike the APIs in https://github.com/vanadium/go.v23, which promises to provide backward compatibility this repository makes no such promises.
