A new mcc_mnc parameter is now optionally passed to connect() in order
to manually register to a specific network with a given MCC+MNC pair.
If no parameter is passed (or None), then the modem will be instructed
to attempt an automatic registration with any available network which
permits it.
We get the MCC+MNC parameter from the MSC/NITB and we pass it to the
modem object at connect time as shown in the modified tests. Two new
simple tests to check network registration is working are added in this
commit.
Ofono modems seem to be automatically registering at some point after
they are set Online=true, and we were actually using that 'feature'
before this patch. Thus, it is possible that a modem quickly becomes
registered, and we then check so before starting the scan+registration
process, which can take a few seconds.
The scanning method can take a few seconds to complete. To avoid
blocking in the dbus ofono Scan() method, this commit adds some code to
make use of glib/gdbus async methods, which are not yet supported
directly by pydbus. This way, we can continue polling while waiting for
the scan process to complete and we can register several modems in
parallel. When scan completes, a callback is run which attempts to
register. If no MCC+MNC was passed, as we just finished scanning the
modem should have enough fresh operator information to take good and
quick decisions on where to connect. If we have an MCC+MNC, then we check
the operator list received by Scan() method. If operator with desired
MCC+MNC is there, we register with it. If it's not there, we start
scanning() again asynchronously hoping the operator will show up in next
scan.
As scanning() and registration is done in the background, tests are
expected to call connect(), and then later on wait for the modem to
register by waiting/polling the method "modem.is_connected()". Tests
first check for the modem being connected and after with MSC
subscriber_attached(). The order is intentional because the later has to
poll through network and adds unneeded garbage to the pcap files bein
recorded.

Implement the Modem.log_info() function, use that instead of logging all modem
properties.
Tweak mo_mt_sms.py print() statements.
Pass modem object to SMS generation to inlcude the modem name as SMS token.

It would be nicer to select the network programs as scenarios, i.e.
independently from the specifics of tests that don't care whether a NITB or a
MSC+BSC is in place. See OS#2270.
For now have a separate script for BSC+MSC+HLR operation to be able to rapidly
get the binaries to work. We might even simply drop the NITB style, in which
case we don't need to make it configurable.
