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)
This is something we need to simulate more complex scenarios,
particularly in the context of frame relay.

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).
