Remove ARFCNs as a concept from resource pool, assign a fixed ARFCN to
each BTS and TRX in the resource pools.
Using ARFCNs on specific bands as resources was an idea that is hard to
implement, because specific BTS dictate selection of bands which
influences which ARFCNs can be picked. That means reserving ARFCN
resources is only possible after reserving specific BTS resources, but
the tester is currently not capable of such two-stage resolution.
Writing handover tests, I got the problem that both BTS in a scenario
attempt to use the same ARFCN.
The by far easiest solution is to assign one fixed ARFCN to each BTS and
TRX. If ever needed, a scenario modifier can still configure different
ARFCNs.
(Due to uncertainty about OC2G operation stability, I prefer to leave
OC2G on ARFCN 50, as it happened to end up being configured before this
patch.)

Before this patch, almost everything was in place to support concurrent
osmo-gsm-tester instances sharing a common state dir. However, during
resource reservation, if the reservation couldn't be done due to too
many resources being in use, osmo-gsm-tester would fail and skip the
test suite.
With this patch, OGT will wait until some reserved resources are
released and then try requesting the reservation again.

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).

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.
