Since the modem iface and the GGSN iface are on the same host/netns,
it's really difficult to conveniently test data plane without getting
routing loops. As a result, either GGSN or modem iface must be moved to
a different namespace. The decision after a few discussions was finally
to move modem interfaces to a different netns.
Expected setup:
* ofono is patched to avoid removing modem if it detects
through udev that its net iface was removed (due to for instance, net
iface being moved to another netns and thus not being reachable anymore
by systemd-udev process running in root netns).
* After ofono is started (and successfully configured all the modems and
detected its net ifaces through syfs/udev), script "modem-netns-setup.py
start" which creates a netns for each modem, naming it after its usb
path ID. net ifaces for that modem are moved into its netns.
* Modem is configured to use 802-3 data format, and as a result the net
iface is configured through DHCP (DHCP req only replied AFTER pdp ctx is
activated!).
* Since osmo-gsm-tester knowns the modem USB path ID (available in
resources.conf), it can run required steps (ifup, DHCP) to configure the
interface. The interface name is provided by ofono to osmo-gsm-tester.
* As a result, any process willing to transmit data through the modem
must be in the modem netns.

This scripts were already being used by osmo-gsm-tester for a while, but
were not avaialable in this repository. Let's put them here to easy find
them and have all this kind of helper scripts together with code using
it.

Used to quickly set modem net interfaces into their own net namespace
(named after modem USB ID path).
The idea is that since osmo-gsm-tester ofono modem.py knowns the USB
path from a modem (path yml attr), it can infer the netns from it and
run a ping process inside it.

IPA style dynamic timeslots (TCH/F_PDCH) support only TCH/F and thus
only full rate codecs are to be used.
On the other hand, OSMO style dynamic timeslots (TCH/F_TCH/H_PDCH) can
use both full rate and half rate, so no need to be restrictive there.

By default, all channels are TCH/F, and as a result we cannot run half

And extra IP address is required/requested on the docker host because
the BSC handling the OML instance is binding to it's address, so we
cannot ask docker to use that one because it fails binding to it.

This change allows recording all interesting traffic for TTCN3 tests,
having GSMTAP and RSL together, because osmo-bsc is configured to pass
the RSL IP of the TTCN3 testsuite emulating a BSC.

Previous implementation was done due to osmo-pcu dying if failed to
connect to not-yet prepared BTS. This is no longer the case, so we can
start osmo-pcu as soon as the socket exists.

First of all, it was found that vty allocation must be forced (-t -t)
during ssh session creation to make sure SIGHUP is forwarded when
session is closed.
Second, since osmo-trx ignores SIGHUP (osmo_init_ignore_signals()), we
must add a wrapper script which converts received SIGHUP into a SIGINT
to stop osmo-trx.

It seems for not yet clear reasons the MS require some time after the
PDCH channels have been activated again to use them reliably. If no
sleep is used between call hangup and gprs activate pdp ctx, the MS
fails to activate the pdp ctx due to QMI error respone to the "Start
network" requested.

We want to write repo name in there, not $dep which actually doesn't
exist in local context of have_repo function. In most cases it's
actually the same because in almost all cases $dep is passed as $1 to
have_repo and thus is the same as local $repo. But in a few recipes
which don't use build_repo directly but instead use have_repo and build
manually, $dep may not point to $repo. That's the case for osmocom-bb
for instance. As a result, "libosmocore" is printed twice, were second
word should be "osmocom-bb".
