This patch implements load_unlock_retries() for the Novatel LTE modem by
using the AT$NWPINR? command to query the number of retries left for
entering PIN1 or PIN2.

When returning an enum value via g_task_return_int, some code assumes
the enum value is always non-negative and thus considers that a negative
value implies an error. This assumption could be invalidated if a
negative value is later added to the enum. To make it less error prone
to future changes, this patch modifies the code to check if the GError
argument to g_task_propagate_error is populated instead.
When the GCancellable is added to the GTask, we can use a single
method call to check for the task being cancelled, and complete it
right away if so.
This patch also clears up the logic in the Novatel plugin, where the
code was trying to return "TRUE" when the task was cancelled, but
wouldn't work as the check-cancellable flag in the GTask is TRUE by
default (i.e. when completing the GTask, if it was cancelled, a
G_IO_ERROR_CANCELLED would be returned by default, regardless of any
other return value set).
This patch also introduces a small variation of the logic in the
Cinterion plugin: instead of running SWWAN=0 before completing the
async action, the command is now sent just after completion of the
async action. This shouldn't be an issue, as the SWWAN result itself
is ignored.
Allocate the results instead of passing them back on the stack, which removes
the "can't complete in idle" restriction. Also always open the QCDM port
since we can't assume it will be open already at this point.
Instead of mixing the QCDM Novatel Snapshot code directly into the
access technology checking code, split it out with its own async
result. At the same time, make sure to open the QCDM port when
it's needed, instead of assuming its already open. Since it won't
always be.
The MMPortProbe object is already referenced by the GTask object for
custom init. Instead of keeping another reference of MMPortProbe in the
CustomInitContext, this patch changes the code to simply obtain it from
the source object of GTask.
See https://lists.freedesktop.org/archives/modemmanager-devel/2017-April/004420.html
g_free and g_object_unref are in form of `void (*)(gpointer)`, which
matches the GDestroyNotify signature. An explicit GDestroyNotify cast on
g_free and g_object_unref is thus not needed.
This is the value which we actually suggest in the manpage for the mmcli
operation, so just use the same one.
Scanning for 3GPP networks may really take a long time, so a specific timeout must be given:
$ mmcli -m 0 --3gpp-scan --timeout=300
Found 4 networks:
21404 - Yoigo (umts, available)
21407 - Movistar (umts, current)
21401 - vodafone ES (umts, forbidden)
21403 - Orange (umts, forbidden)

Instead of setting up a custom timeout source to poll the connection status, use
the generic logic in the base bearer object, and just re-implement the command
used to check the status.
All ports of the same modem reported by the kernel will all be associated with
a common 'uid' (unique id), which uniquely identifies the physical device. This
logic was already in place, what we do now is avoid calling it the 'sysfs
path' of the physical device, because we may not want to use that to identify
a device.
This logic now also enables the possibility of "naming" the modems in a unique
way by setting the "ID_MM_PHYSDEV_UID" property in the "usb_device" that owns
all the ports.
E.g. a custom device has 4 modems in 4 different USB ports. The device path of
each USB device will always be the same, so the naming rules could go like this:
$ vim /usr/lib/udev/rules.d/78-mm-naming.rules
ACTION!="add|change|move", GOTO="mm_naming_rules_end"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.1", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-1"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.2", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-2"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.3", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-3"
DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.4", ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-4"
LABEL="mm_naming_rules_end"
Each of the modems found will have a unique UID retrieved from the previous list
of rules. Then, "mmcli" has also been updated to allow using the UID instead of
the modem DBus path or index, e.g.:
$ sudo mmcli -m USB-MODEM-1
/org/freedesktop/ModemManager1/Modem/0 (device id '988d83252c0598f670c2d69d5f41e077204a92fd')

This patch makes declarations bind to definitions within the same module
to prevent the potential ambiguity if referenced directly.
AddressSanitizer think they violated one definition rule, although
those symbols are accessed by address through their modules and do
not depend on the order of the libararies loaded.
For Dell-branded Novatel, Sierra and Ericsson modems.
The Novatel plugin will no longer accept every Dell-branded modem, which was
the current situation. Instead, a new Dell plugin will take care of probing for
the correct vendor string, and based on the results create a specific Novatel,
Sierra or Ericsson modem.
In order to properly support this, the Novatel, Sierra and MBM plugins now
export their implementations into non-inst libraries that the Dell plugin will
import.
Also, for now, the Dell plugin doesn't make any difference between e.g. Sierra
or Ericsson MBIM implementations, just a generic MBIM modem is created in both
cases, as that is anyway what the Ericsson MBM and Sierra plugins do already.

The QCDM port commands are never cached, so remove the option from the command()
method. Will also simplify command caching afterwards as it will be an AT-only
thing.
The Novatel LTE modem only uses its primary AT port for AT commands.
Instead of referencing any existing secondary port, this patch changes
MMBroadbandBearerNovatelLte to explicitly use the primary port during the
connection and disconnection sequence.

This patch replaces mm_bearer_report_disconnection() with a more generic
mm_bearer_report_connection_status(), which allows reporting any
connection status of a bearer. This further allows getting rid of those
custom report_connection_status functions in plugic specific bearer
subclasses.
Note that while plugin-specific implementations can receive multiple
'MMBearerConnectionStatus' values, the generic implementation is only allowed
to receive DISCONNECTED. Plugins need to make sure that they process all the
other status values, and only report DISCONNECTED to the parent when required.
MBM:
The MBM bearer implementation of report_connection_status() expects either
CONNECTED or DISCONNECTED. If any of these is received and there is an ongoing
connection attempt, the corresponding operation will be completed. If there is
no connection attempt, we will just handle the DISCONNECTED state, calling the
parent method to notify that the modem got network-disconnected.
Icera:
The Icera bearer implementation of report_connection_status() expects either
CONNECTED, CONNECT FAILED or DISCONNECTED. If any of these is received and
there is an ongoing connection or disconnection attempt, the corresponding
operation will be completed. If there is no connection or disconnection
attempt, we will just handle the CONNECT FAILED and DISCONNECTED states,
calling the parent method (always with DISCONNECTED) to notify that the modem
got network-disconnected.
Option/HSO:
The Option/HSO bearer implementation of report_connection_status() expects
either CONNECTED, CONNECTION FAILED or DISCONNECTED. If any of these is
received and there is an ongoing connection or disconnection attempt, the
corresponding operation will be completed. If there is no connection or
disconnection attempt, we will just handle the CONNECTION FAILED and
DISCONNECTED states, calling the parent method (always with DISCONNECTED) to
notify that the modem got network-disconnected.
Huawei:
The Huawei bearer implementation of report_connection_status() expects either
CONNECTED or DISCONNECTED. These messages are not used to process pending
connection or disconnection attempts; so if they are received while one of
these is on-going, it will just be ignored. CONNECTED reports are also
ignored, so we will just handle the DISCONNECTED state, calling the parent
method to notify that the modem got network-disconnected.
Altair-LTE:
The Altair-LTE bearers will only report DISCONNECTED on network-disconnected
cases. There is no custom report_connection_status().
Novatel-LTE:
The Novatel-LTE bearers will only report DISCONNECTED on network-disconnected
cases. There is no custom report_connection_status().
