sync: remove use of protobuf extensions in protocol to reduce static init overhead.
Instead, we now use optional fields in EntitySpecifics. Because the tag numbers remain
the same, this is a wire-format compatible change.
This incurs a (#datatypes * sizeof(void*))*#sync_items memory cost, due to storing extra pointers. In practice, for a typical account on windows this amounts to < 200k, and the static init cost is believed to be greater.
Note - upcoming features in protobufs may let us eliminate this extra memory overhead.
Also: The testserver tests were broken on ToT due to a bug in _SaveEntry's saving of mtime which is fixed in this patch.
