tgz files in trials can be categorized in subdirectories, allowing to
select different bianry files at runtime based on the target run node
which is going to run them. This way for instance one can have a binary
linked against libs for eg. CentOS under run_label "centos/" or an ARM
target under "arm", and then use "run_label: arm" on the resource using
it.

Since the process is run in the background through the wrapper bash
script, stdin was disabled there. By explicitly redirecting the bash
process stdin we make sure it is always able to read from it.

we've only waited when running with ZMQ but in fact we need
to always wait because the UE may need some time to
gracefully exit, i.e. send the detach request and shut down correctly.
this is checked in cleanup() and verity_metrics(), so also before copying back
the CSV metrics. But we only wait once.

this allows to sum dl_brate and ul_brate and perform
the known operations, like max, average, etc. on both
UL and DL bitrate combined

.. one could calculate the average of DL and UL bit rate with:
ue.verify_metric(1e6, operation='avg', metric='dl_brate+ul_brate', criterion='gt', window=test_duration)
and veriy that it's average is greater than 1 Mbit/s

this allows to calculate the rolling average over a specific
window in time and take the maximum of that
this is useful to get average value for 30s UDP traffic for
example from the UE metrics

This is useful since remote processes we run under ssh end up merging
both remote stdout and sterr into local stdout.

It is known that sometimes srsENB hangs until it is killed -9, specially
when using ZMQ backend. Let's use RemoteProcessSafeExit in order to make
sure it is killed in an acceptable time (srs binaries use some
preventive sigalarm 6 seconds auto-kill procedure, hence we use 7
seconds) before next test is started and potentially try to re-use the
same ENB and fails due to previous one still running.

The API was doing far more stuff than its name indicated. Even more
important stuff, like making sure the process is killed at the end with
-9 after ssh connection is dropped.

This allows inheriting suites or scenarios from eg. sysmocom/ dir, while
still allowing to apply new suites and scenarios on top.

It has been notified that current configuration system is difficult to
understand and to use, so it has been envisioned to refactor it a bit.
The idea is that the user passes a -c path/to/main.conf file, which in
turn contains whatever osmo-gsm-tester main settings supports (basically
what old paths.conf used to be, plus some files harcoded to the same -c
directory are now configurable through the main configuration file).

smpplib modules are used in several places, so it's not enough to import
them in the constructor since they are only imported for the function
scope.

Environment variable OSMO_GSM_TESTER_CONF is marked as deprecated and an
error is logged each time it's used. Same feature is available through
"-c" command line parameters, so having the envvar only makes things
more complex for no good reason. It cannot yet be completely dropped
since some environemnt still make use of it. Give some time to users to
adapt their setups.
Other environment variables setting some config apths can be dropped
since they are not being really used in any setup.

we need to make the rf_port a param in the cell list because for CA with
two cells on different EARFNCs, the RF port is different
for two cells without CA on the same EARFCN the RF port is the same
so we need to be able to configure it

On older versions apparently upon child termination due to SIGINT
subprocess.poll() returned 1. On new python versions (such as 3.8.2),
-2 is returned, according to documentation:
A negative value -N indicates that the child was terminated by signal N (Unix only).
Let's catch the SIGINT in the child process and exit with a known 42
value to fix different behavior.

If using python 3.8.2, the trailing comma at the end of parameters is
not longer there (probably got fixed, since it's not needed). That
change breaks expected output.

This test currently only works with AmarisoftENB and srsUE, because:
* srsENB has no handover support yet
* AmarisoftUE doesn't provide any known way to verify handovers.
As a result, it usually runs with following filters and modifiers:
amarisoftenb-rftype@uhd+srsue-rftype@uhd+mod-enb-ncells@2+mod-enb-meas-enable
The get_counter() API may change in the future based on information
available from other implementations.
