Add read/write callbacks to attribute server
These callbacks will allow profiles to act before an attribute is read
and after it is written, to e.g. update the attribute value to/from an
external source.
Note that by the time the callback is called, the necessary security
checks (attribute permissions, authentication and encryption) were
already performed by the core attribute server.
The callback can optionally return an ATT status code, which will be
sent to the client using an Error Response PDU.
