This function can be used by a server to retrieve data sent early
in the handshake processes when resuming a session. This is used
to implement a zero-roundtrip (0-RTT) mode. It has the same
semantics as gnutls_record_recv().
This function can be called either in a handshake hook, or after
the handshake is complete.
The number of bytes received and zero when early data reading is
complete. A negative error code is returned in case of an error.
If no early data is received during the handshake, this function
returns GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE. The number of
bytes received might be less than the requested
