StatsD_Checker: Allow building without VTY support
Some programs may support exporting to statsd, but may not support the Osmocom VTY set of commands to send reports, or not have a VTY at all.
The current StatsD_Checker implementation as it is now is not totally useful without VTY code. a Follow-up patch will provide new APIs and improved implementation to use it without VTY.

StatsD_Checker: Simplify by getting rid of StatsDExpectPriv
Get rid of extra record, we have plenty of them and we'll have more once we add new APIs to work without VTY. While doing so, simplify the expect loop by maintaining a counter.

StatsD_Checker: Allow running without VTY support
New features are added to the public API of StatsD_Checker which make it possible to use it...
* without "stats reset": Feature to take snapshots (f_statsd_snapshot()) which can later be used to validate expectancies with values relative to the snapshot, using API f_statsd_expect_from_snapshot(). This way, one can do: """ var StatsDExpects statsd_exp := { /* relative expectancies here... */ }; var StatsDMetrics statsd_snapshot := f_statsd_snapshot(f_statsd_keys_from_expect(statsd_exp)); /* do some test stuff here changing the state of the IUT... */ f_statsd_expect_from_snapshot(statsd_exp, snapshot := statsd_snapshot); """
* without polling ("stats report"), aka with periodict reporting: New parameter wait_converge in f_statsd_expect(), which allows overcoming race conditions with StatsD server processing older incoming metrics due to periodic reporting. This feature also allows a test to wait until a state changes in the IUT.

testenv: support obtaining talloc reports
Allow setting vty_port= and vty_host= (default: 127.0.0.1) for SUT components in testenv.cfg. Pass the values as OSMO_SUT_PORT and OSMO_SUT_HOST to the testsuite, so ttcn3-tcpdump-stop.sh generates talloc reports after running test cases.
The next patch will add vty_port/vty_host to existing testenv.cfg files.
I have considered enabling the talloc report only conditionally (e.g. with a --talloc-report parameter). But previous behavior in docker-playground was also that we created them unconditionally where OSMO_SUT_PORT/HOST was set, and they are generated almost instantly so it did not seem necessary to make this conditionally.

HTTP_Adapter: Rename s/g_pars/g_http_pars/
The HTTP_Adapter component is a probable candidate to end up as part of another component extending it, like the Prometheus_Checker coming up soon. Since the fields in HTTP_Adapter are available to subclass components, that means they cannot use the usual "g_pars". Rename the self-enclosed "g_pars" in HTTP_Adapter to let subclasses use it.

Misc_Helpers: Introduce API helper f_str_startswith
Counterpart of f_str_endswith(), this API is usually available in several programming languages like python, and it's handy to have since it's usually used and hence dev doesn't need to think on how to implement it using regexp, etc.
This API will be used in a follow-up patch implementing Prometheus metrics checker module.

lapdm: remove
In the related patch, lapdm/L1CTL_Test.ttcn has been moved to bts/BTS_Tests_LAPDm.ttcn. The remaining files in this directory are unused. Remove them to unclutter the repository a bit.

hnbgw: move vc_PFCP from ConnHdlr to test_CT
A logical relation between the PFCP emulation component (acting as the UP function) and its ConnHdlr components is one-to-many. It's unusual for the ConnHdlr components to have their own emulation component, especially when a testcase spawns many of them. This renders the dispatch function of the PFCP emulation component useless.
The HNBGW testsuite, which is using the PFCP emulation, does not spawn more than one ConnHdlr component, so there was no problem with that so far. Let's move the PFCP emulation to test_CT, in order to allow spawning more than one ConnHdlr and to make the component hierarchy less confusing.

library/PFCP_Emulation: fix routing of incoming PDUs
Before this patch, the PFCP_Emulation component was unable to route incoming PDUs properly. The problem is that the SeqNr and SEID were neither stored nor updated whem sending outgoing PDUs, and thus remained unbound all the time.

s1gw: move t_ConnHdlrPars back to S1GW_Tests
This is a partial revert of 956bf05e7, which moved the t_ConnHdlrPars from module S1GW_Tests to S1GW_ConnHdlr and added f_new_ConnHdlrPars().
The problem is that we want to assign module parameter values to some fields of the ConnHdlrPars record, but TTCN-3 does not allow to access module parameters of one module from another. Having to add more and more parameters to the proxy function f_new_ConnHdlrPars() is highly inconvenient.

testenv: display current test name on ^C
When running a whole testsuite and getting a lot of output, it can be useful to know which test was currently running when pressing ^C. Now that we have a function that provides this information, show it to the user.

testenv: get coredump + backtrace on crash
If the SUT or another test component crashes, check if a matching coredump was registered in coredumpctl. If that is the case, then copy it into the testdir and print + store the backtrace.
This solves the problem that it is especially tricky to get a good backtrace when a component crashes inside a container. One needs to grab the coredump from the host (usually handled by systemd-coredump, we cannot override /proc/sys/kernel/core_pattern for containers so it can't be handled in the container), then put the coredump into the container and finally run gdb to get the backtrace inside the container (where proper libraries and debug symbols are). This patch automates all of these steps.
