A Huawei E173 (with FW 11.126.15.00.445) seems to stop responding on the
primary port (ttyUSB2) when the CGACT is resent on the data port (ttyUSB0).
The CGACT-on-data-port was originally added as a fallback attempt to get
single-port modems to disconnect when all other methods failed.
For single-port modems, the primary port is also the data port so this
patch will have no effect.
For multi-port modems, this patch will retry the CGACT on the primary
port which has a higher chance of success because we already know
the primary port is talking to us, while the data port may still
be stuck in PPP mode.
The MMBroadbandModemQmi will not create a MMSimQmi until the unlock status has
been checked, and therefore this means that when the SIM object is being created
we already know whether the modem supports DMS UIM commands or not, so avoid
further fallbacks in the SIM object.
Newer modems like the MC7455 don't implement the "DMS UIM" commands in the
DMS service, and therefore these modems need to use the UIM service directly.
We include a new flag to detect whether any of the DMS UIM commands is flagged
as invalid, and if so, we'll fallback to the UIM specific implementations for
all.
libqmi version bump to 1.13.7, which includes the new required methods.

The port opening logic is changed completely.
Before this change, the logic would only try 802.3 setting via CTL when the
QmiDevice was being open.
With this new change, instead, we'll use WDA and the new libqmi APIs to query
the link layer protocol expected by both the device and the kernel. If the LLP
matches in both, we assume we're done; if they differ we'll try to update the
LLP expected by the kernel to the one setup in WDA. This change will allow us
to run with the modem using raw-ip if that is what WDA reports by default.
Also bumped the libqmi version to 1.13.6, which has support for the new required
APIs.
Response parsing was being done in different places for AT and QCDM subclasses;
in the case of AT it was being done early, before returning the byte array in
the mm_serial_port_command_finish() response. In the case of QCDM, it was being
done after mm_serial_port_command_finish(), and that was forcing every caller to
cleanup the response buffer once the response was processed.
With the new logic in this patch, the response is always parsed (i.e. looked for
a valid response or an error detected) before mm_serial_port_command_finish()
returns, and actually this method now returns a totally different GByteArray,
not the internal response buffer GByteArray, so there's no longer any need for
the caller to explicitly clean it up. The one doing the cleanup is the parser
method itself in every case.
This change also allows us to return serial port responses in idle, but that's
not changed for now as there's no immediate need.
When valid responses were returned to the caller of the serial command, the
caller itself was responsible for removing from the GByteArray the data that
it was successfully processed (all the data in AT, just 1 message in QCDM). But,
the same logic was missing for the case of errors; we were not explicitly
removing the response and therefore in some cases we would see it propagated
into the next command response. It was common to see this issue when the echo
removal was disabled in the serial port, as in Option/HSO modems:

Since GLib 2.42, the sockets that are added to socket listeners may no longer
be closed automatically when the listener is finalized. In order to avoid that,
we will keep our own socket reference and close/unref it ourselves.
This issue was preventing adding new test cases with the same port names.

We were wrongly using a main loop in the port context thread to manage the
global main context. That was silently making the DBus property notifications
kind of work, as they were being updated via another thread, so here we could
just sleep() and recheck the property values.
Given that having that unrelated thread updating the dbus properties of our
MMManager object is not a good thing, we'll instead totally ignore that and
fully re-create the MMManager in each iteration with the sync() method, which
has its own internal thread.
Instead of creating a new main context to be used in the thread, we were using
the global context. So, fix that, and create a totally new pair of main context
and main loop to be used within the thread.
We were trying to load the generic modes supported reported by either *CNTI=2 or
AT+WS46=?, so that then we could filter out the MBM-specific modes unsupported.
But, this may not be ideal, as both these two commands may fail:

Instead, we'll ask the modem for the list of modes supported, and return that
directly.
Not making them '--location-enable|disable-signal' because that's the pattern
used to enable/disable location sources. Instead, use the '--location-set-*'
pattern, as that is what we're already using for the other location setup
update.
The default setup uses a refresh time of 30s, which means that even if the GPS
location updates are received at a higher frequency, the DBus interface will
still expose at most one update every 30s.
This patch includes a new "SetGpsRefreshTime()" method in the Location
interface, which takes a single 'u' parameter, specifying the refresh rate to
use, in seconds. This method also allows 0 being passed, which will make the
implementation to publish the GPS location updates are soon as ModemManager
detects them.
Along with the new method, a "GpsRefreshTime" read-only property is exposed
to specify the refresh time in effect.
The new method and property will only be applicable if the device has GPS
capabilities.

Use the "WDS Get Packet Statistics" method to query for the ongoing number
of bytes transmitted or received. The QMI implementation uses different WDS
clients for IPv4 and IPv6; the stats reported are a combination of the values
retrieved from both WDS clients.
