Our TTCN3 implementation of the IPA multiplex with CCM handshaking
has been based on some wrong assumptions about the protocol logic.
To make the code stricter, we
* send an ID_ACK immediately after connecting TCP in a client
* separate client and server CCM responder logic
* always respond with ID_ACK to ID_RESP (we accept any identity)
Also, as the Osmocom CTRL interface uses an IPA multiplex but no CCM,
we introduce a boolean variable (and function argument) to clearly
enable/disable CCM support in a given IPA_Emulation component. The
CTRL_Adapter has been modified to use this flag to disable CCM.
This also removes the need of cherry-picking
