Philipp Maier ac791564f1 GTPv2_Emulation: improve accessibility of unit-data (TEID0) 
When GTPv2 unit-data is passed around, there is always the problem that
it is routed to the MTC_CT (TEID0). The reason for this is that GTPv2_Emulation
cannot determine a specific receiver component because unit-data does
not contain any addressing fields that would identifiy a specific vc_conn.

In GTPv2_Emulation there is already a mechanism implemented that detects
responses by their sequence number. Untfortunately this does only work
when the vc_conn has send a unit-data message before so that the
sequence number of the response can be guessed.

In case the first messages comes from the IUT, there is no way to
determine the receiving vc_conn, so this message is then routed to the
MCT_CT (TEID0). This can be a problem for testcases that run from inside
a ConnHdlr componet.

The solution that is proposed in this patch uses a mechanism that allows
to create an expectation for a specific messageType. When the GTPv2_Emulation
sees a unit-data message with the expected messageType, it will forward
it to all ConnHdlr (vc_conn) components that have registered for this
messageType previously.
