Harald Welte f7191679aa SGSN_Tests: Make more helper functions gb_index aware
The gb_index indicates through which Gb link (simulated
RAN/PCU) a given message shall be sent.

Harald Welte ca36246737 SGSN_Tests: Make f_gmm_attach() and f_gmm_auth() work on gb_idx != 0
Let's make sure the related functions can be used on other gb_idx,
i.e. via another Gb interface (and hence simulated RAN/PCU) than
the first one.

Harald Welte 645a151f69 sgsn: Add test cases to verify SABM handling on LLGMM + LL5
As OsmoSGSN doesn't implement ABM, the correct resposne to any SABM

Harald Welte a05b807922 sgsn: Add TC_llc_null to test if SGSN survives a LLC NULL packet
This test case reproduces a bug in OsmoSGSN where it would crash
as a result to sending LLC NULL frames.

Alexander Couzens c7dddbd7d0 Ensure BcdMccMnc is encoded as 24.008 10.5.5.15
PCU is using BcdMccMnc as it's encoded as 24.008.
But SGSN code is using it as it would be byte by byte
sorted.
