Missing ! for strncmp() meant the test was backwards and would
erroneously report 1xRTT and EVDOr0 when those access technologies
were not in use.

Dell Snapdragon X62 before FCC Unlock reports no radio interfaces
from QMI and no device capabilities from MBIM. Instead of asserting
in mm_filter_supported_modes() when called from
mm_supported_modes_from_qmi_supported_modes_context() gracefully
handle the lack of supported modes.

MBIM modems report RSSI and sometimes don't report more detailed RSRP
and SNR info their MBIMex v2 signal-state replies. RSSI gets reported
for every other access technology, and while it's not as good a signal
indicator as the others, we might as well show something.

Consistently interpret the modem's reported custom data class when
loading current mode, supported mode, supported capabilities,
setting current mode, and current access technology.
Normalize the data class to include any custom data class immediately
after reading it from any MBIM message. De-normalize it when sending
back to the modem when setting current modes so the modem receives
MBIM_DATA_CLASS_CUSTOM for the custom mode.

For modems that need more time to respond to AT port probes (like some Telit devices,
and Cinterion-based Telit MV31/MV32) allow a custom number of AT probe tries on a
per-port basis for generic probing, or plugins that opt into this functionality.

If the old IMSI was unavailable because the SIM was locked, but now
is available because the SIM was unlocked, don't treat the SIM
properties change as a hotswap that may trigger dropping and re-probing
the modem.

If multiple plugins are selected for probing a modem with AT probes,
earlier plugins may only request some probes but not all. When
those probes complete successfully, subsequent plugins won't re-do
the probes that were already completed, but jump to ones that
haven't yet been done.
For example, plugin A may request only AT probes but plugin B
may request AT, AT_PRODUCT, and AT_VENDOR. Plugin B will start
with AT_PRODUCT probes because plugin A already completed the AT
probe.
The code in probe_step() only opened the serial port for the
AT probe, I guess assuming that all AT-type probes would be
done in sequence. But in the above scenario they are not.
Instead, make sure the port is opened for all AT style probes
that have not yet been executed.

Add some mmcli D-Bus timeout slack, making them slightly higher than the
ModemManager internal timeout, to ensure the cli doesn't time out the
D-Bus call when MM succeeds.
For 3GPP scan, some modems appear to have internal 5 minute timeouts,
so ensure MM doesn't time out right before the modem returns results:

With the FDO CI templates, the first container used must
be .fdo.container-build@ubuntu which builds the actual
container the rest of the pipeline can use with
.fdo.distribution-image@ubuntu.
.fdo.container-build@ubuntu uses a static 'image:' tag for
its job base image and then pushes to the project registry.
If the first job incorrectly uses .fdo.distribution-image@ubuntu
instead, it appears to fail for MR branches because that target
uses CI_REGISTRY_USER as part of the 'image:' tag which gitlab
sets to the username of the submitter. Which of course fails
because that user has never built the image before...

Referenced commit broke custom init flows because the AT port
was not opened when custom inits were run, which was the case
before the commit landed.
Rework probing flow to follow a step model like much of our
other code, and ensure that the AT port is opened as part
of the custom init flow.

If the system and modem are independently powered, a system restart may
leave one of the modem's AT ports in PPP mode. On restart this may cause
AT probing to fail. The modem may terminate PPP after receiving bogus
HDLC frames from QCDM probing (since PPP also uses HDLC framing), and
return "NO CARRIER". We can use this to restart AT probing now that
PPP is down and auto-detect the expected additional AT ports.

Open the AT port from the regular port probe flow rather than doing
that one-off at the beginning of probing. That lets us re-open the AT
port later if needed, based on QCDM/QMI/MBIM probing results.
