`ID_MM_QUALCOMM_SAHARA` environment variables for all devices.

The NL668-EAU 4G, 3G, 2G CAT4 is a modem from fibocom and is using a diffrent
USB_VID for this modem. By adding the new USB_VID, the 'fibocom' plugin is
now responsible and not the 'generic' plugin.

L850 modems running a firmware version less than 18500.5001.0.7 and
using AT&T SIM cards with MCCMNC 310280 do not support specifying
"partner" settings in the MBIM operation to set the LTE attach
configuration.
The implementation in the generic MMBroadbandModem object should fit
well instead of the custom implementation.
There is also no need to specify via udev tags which is the initial
EPS bearer context id, we try to automatically guess it in runtime.
Let the caller of mm_iface_modem_set_power_state() know which was the
power state in the device before the actual update happened.
This is useful in cases where we want to temporarily switch to a given
power state (e.g. low) before returning to the original power state.
The generic MMBroadbandModemFibocom object uses the shared Fibocom
settings to load the update settings. This logic does not use the
Private info right now, but there is no reason why it wouldn't do it
in the future. Also, for consistency, it makes sense to ensure the
shared interface setup is the same in all implementations, we should
not have only some allowing to initialize the Private info.
Requiring an explicit set of drivers should only be done when we have
different plugins supporting different types of devices of the same
manufacturer based on the drivers in use (e.g. as in the Sierra case).
When the plugin includes a list of required drivers, the plugin filter
will only assume the plugin can be used if at least one of the
available ports is exposed with one of the drivers in the list.
Because of this, if we start probing some ports before all the
expected ports are reported, we may end up not selecting a given
plugin just because the driver match should have been done in a
not-yet-notified port.
E.g. on system boot:
* ttyACM0 is notified.
* min probing time elapses so ttyACM0 probing starts
* Fibocom plugin is not selected for ttyACM0 as no matched
driver ("cdc_acm") is given in the the list of drivers of the
plugin.
* cdc-wdm0 and wwan0 drivers are notified.
* MM creates generic MBIM modem with the Fibocom plugin, but without
XMM features support, because the ttyACM0 port probing was not done
by the Fibocom plugin.
And if we reset the modem after that:
* ttyACM0 is notified.
* cdc-wdm0 and wwan0 drivers are notified.
* min probing time elapses so probing starts for all ports
* Fibocom plugin is selected for all port probings as "cdc_mbim" is
listed in the list of drivers of the plugin.
* MM creates XMM-capable MBIM modem with the Fibocom plugin.
To address limitations in reading IP_TYPE information (in some cases) for profile requests,
default to IPv4v6 (dual-stack) for profile requests and IPv4 only for user requests (to ensure backward compatibility)
if nothing specific is requested. This ensures network compatibility across IPv4 and IPv6 networks,
preventing potential connectivity issues in IPv6 environments.
NL668 doesn't correctly support more than one multiplexed PDN
connection. Limit this explicitly so that it never attempts to use
more than one.
# mmcli -m a --simple-connect="multiplex=requested,apn=internet,ip-type=ipv4v6,apn-type=default"
successfully connected the modem
# mmcli -m a --simple-connect="multiplex=requested,apn=internet2,ip-type=ipv4v6,apn-type=default"
error: couldn't connect the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unsupported: Invalid bearer properties: Maximum number of multiplexed bearers reached'
We are going to allow including the plugin sources built within the
ModemManager daemon binary; moving the sources within the daemon
sources directory makes it easier.
