testenv: Dockerfile: rebar3 version via apt-cache

When building for Debian Unstable, we need a higher rebar3 version so it
is compatible with the Erlang OTP version in the distribution. Get the
version of rebar3 from the distribution via apt-cache and download it
instead of hardcoding a version number.

testenv: init: check distro argument early

Check the --distro argument and print a proper error, instead of failing
later on with a stack trace if it is unsupported.

CCID: Check if reader times out while expecting procedure byte

A case 2 APDU (according to ISO 7816) is sent toward the reader. The
reader expects a procedure byte or a status word. If none of these are
sent by the SIM the reader must timeout and send an error message back
to the host.

CCID: Check if reader handles Abort correctly

The tests aborts an ongoing case 2 APDU (according to ISO 7816). The
SIM responds with a NULL procedure byte so that the reader does not
time out.

The abort messages are sent on both, the control pipe and the bulk
pipe with the same sequence number.

This test fails with osmo-ccid-firmware, because the abort
message/handling is not yet implemented.

deps: use a fork of titan.ProtocolEmulations.SCCP

The fork adds support for sending UDTS via
ASP_SCCP_N_NOTICE_req.

Change-Id: I8c0de4dab088930d5d7a9febcbebcb5e1f9411e8

stp: add ASP_SCCP_N_NOTICE_req support and f_asp_tx_notice()

Wire ASP_SCCP_N_NOTICE_req as a simple passthrough in TCAP_CODEC_PT,
so test components can send UDTS via the existing SCCP_TCAP port.
Add f_asp_tx_notice() to STP_Tests_TCAP as a convenience wrapper.

CCID: Check if reader times out after first status word

A case 1 APDU is sent towards the reader. The reader expects two status
words. If only the first word is sent by the SIM, the reader must
timeout and send an error message back to the host.

CCID: Send a wrong procedure byte towards the reader

A case 2 request (according to ISO 7816) is sent and a response with
data is expected, but the first byte replied by the SIM is not a
procedure byte, nor a valid status byte.

This text expects the reader to return an error that states an incorrect
received procedure byte.

STP_Tests_TCAP: Fix ipa_to_ipa testcase

tcap routing doesn't work the way the test thinks. E.g. a Begin can't be
routed to a special destination because it does't contain a dtid which
is needed to route to the correct ASP.

STP_Tests_TCAP: Test routing of fragments in TC_tcap_loadshare_ipa_tcap_range_success_pc

A TCAP Begin will cause the stp to create a cache entry and route
according to that. Send only a TCAP Continue so we check the tcap range
routing logic.

eIM, IPAd: migrate from SGP.32 V.1.0.1 to SGP.32 V.1.2

SGP.32 V.1.2 is not backward compatible to SGP.32 V.1.0.1. This patch updates
the ASN.1 specification and the TTCN3 templates and types accordingly.

It also applies the bare minimum of changes required to compile the eIM and IPAd
testcases.

bts: TC_pcu_interf_ind: check reporting interval instead of absolute FN

Recent osmo-bts commit 53f0ec29 broke TC_pcu_interf_ind:

  Verdict: fail reason: Odd TDMA frame number := 935

There's no requirement that periodic interference reports must land
on a TDMA frame number satisfying 'fn mod 104 == 0' - only that they
keep arriving every configured averaging period.  Instead, verify
that the interval between consecutive reports equals 104 TDMA frames
(1 SACCH period), using the new f_gsm_fn_sub() helper.

stp: for TCAP loadshare: use NI == national

Use a non-zero NI. The TCAP tests don't check it
on the receive path, but the osmo-stp is checking
it if it matches the configuration.

Revert "bts: limit stderr logging to ERROR to avoid long write() to ext4 fs"

This reverts commit 3c798765f04dd7428c76e3c5cbf3f2ee27a0af4d.

Reducing logging verbosity did not help: we're still seeing the clock
skew errors and restarts.  This makes debugging harder, and is not
relevant anymore because we've switched to tmpfs [1].
