This will prevent subsequent failures from overwriting the verdict so we
can easily see the root cause of the test failure.
Using testcase.stop instead for errors internal to our test
infrastructure to mark them as test errors instead of failed.

Before this patch, we had some problems related to synchronization
between the IPA transport, SCCP emulation and BSSAP layer in SCCPlite
configurations.
This code ensures that f_bssap_init() will block until the IPA
connection (client or server) is established, and then start the SCCP
and BSSAP emulation components in the right order.
This in turn ensures that the initial BSSMAP RESET that we're sending
from the TTCN-3 side is only sent once the IPA connection is fully
established, and the CCM Identity handshake has happened before.

When sockets cannot be bound or connected, the existing TTCN-3 code prints
the following rather cryptic error messages:
"IPA-CTRL-IPA(47)@f70ff1fd5cfd: Dynamic test case error: Using the value of an optional field containing omit. (Transport endpoint is not connected)"
The "Transport endpoint is not connected" sort-of gives it away, but
let's make it more explicit by introducing explicit checks for the
res.connId and manual setverdict(fail) statements with proper error
message.

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

Let's use the preprocessor to avoid IPA_Emulation pulling *all*
dependencies into each and any of our projects. The code readability
suffers a bit from the many #ifdefs, but compilation speed increases
if we don't have to pull in all those (recursive) dependencies.
After all, a BTS test case will never need SCCP, GSUP or MGCP.
