Pau Espin 494e8b3e55 Start BSSGP_CT and NS_CT as alive-type component in all testsuites 
This was already done in PCU_Tests and Gbproxy_Tests, let's to it
everywhere.

Alexander Couzens 6a363196f4 fr/fr-net: use correct DLCI range for test cases 
DLCIs are only valid >= 16.

Harald Welte 7504c4dc4b fr: Randomize packet size used in TC_ul2dl_ud() 
This allows us to test with a variety of packet sizes up to [close to]
the MTU of the underlying transport (configurable by modulepar)

Harald Welte 27119672d2 fr: Add TC_ul2dl_ud 
This test case tests NS-UL-UNITDATA transmit and expectes the exact same
LLC PDU to be sent back as NS-DL-UNITDATA.

This way we can verify that both uplink and downlink paths are working,
and that no messages are lost.  It works stable here on my laptop,
showing that if we test the TTCN3 NS + BSSGP code over a E1 line
against another instance (fr against fr-net) works reliable.

Harald Welte f1f23bf785 fr: Generalize and document functions 
This prepares a lot of the FR_Tests functionality to be re-used in more
test cases.

Harald Welte 5e78788c4e fr: Make TC_foo() actually terminate 
Rather than running in an endless loop (useful for manual tets),
terminate each UE_CT after sending 50 packets.  Also adjust the ramping
and timeouts in a way that it manages to terminate ahead of the guard
timeout.

Harald Welte d6de98418c FR/FRNET: Introduce simplistic simulation of UEs 
Let's start a number of per-UE/TLLI component on each BVC, and generate
some uplink traffic with random-payload 512-byte LLC frames.  The
FRNET(SGSN) side simply ignores all of those by means of a
CreateCallback.

Harald Welte 4d112c926c BSSGP_Emulation: Allow a "CreateCb" to handle unknown inbound TLLI 
The existing BSSGP Code assumed that the TLLIs were always known "a
priori" by the test case.  With the newly-introduced create_cb,
the user can provide a function to handle any incoming messages for an
unknown TLLL.  The default handler behaves like before: fail +
terminate.

Harald Welte de6f3ee592 FR/FRNET: Dynamically create number of BVC at runtime 
We don't want the number of NSE and the number of BVC to be a
compile-time choice, but rather something dynamic at rutime.  This
allows configuration files to define those details.

Harald Welte 90f1974fb0 NS_Emulation: Support multiple NS-VC within one NSE (NS-VCG)

Harald Welte 023b61b2cb FR/FRNET: add Frame Relay emulation 
Add frame relay testcase for BSS and SGSN side.
The test cases require hdlc interfaces (based on
dadhi with super channels and no lmi).
