kdbus: add CMD_UPDATE_METADATA ioctl (reinitialize connection metadata)
Added to satisfy efl/launchpad developers' request.
Tizen code routinely performs the following operation sequence:
1. create kdbus connection
2. update seclabel
3. rely on updated seclabel
CONN_INFO has always returned seclabel collected at HELLO time (behavior
consistent across all kdbus versions and documented in kdbus man). This
would break step 3 of the above sequence.
KDBUS_CMD_UPDATE_METADATA ioctl updates a connection's metadata to
reflect the current state. Metadata is collected in the exact same way
as during HELLO.
Semantics Required by efl/launchpad can be obtained by altering the
sequence like so:
1. create kdbus connection
2. update seclabel
+2b. ioctl(connection_fd, KDBUS_CMD_UPDATE_METADATA);
3. rely on updated seclabel
