Currently, LM940 is expected to have not LTE band extended, however they
have been introduced since version 24.01.516.
This change adds a software revision compare function for Telit modem
limited to LM9x0 modems (LM940 and LM960 share the same revision format
string) to verify if the current LM940 software revision is equal or
newer than 24.01.516 and enable/disable LTE band extended accordingly.
Currently, mm-shared-telit:Private:alternate_3g_bands value provided via
ID_MM_TELIT_BND_ALTERNATE tag.
This commit maps the value of alternate_3g_bands to the modem model,
detected via software version string.
Currently, mm-shared-telit:Private:ext_4g_bands value is inferred from
the #BND? response, based on the convention that the #BND? response has
4 tokens only if the modem has LTE extended bands.
This commit maps the value of ext_4g_bands to the modem model, detected
via software version string, which is a more reliable source.
Currently functions dealing with #BND request
- mm_telit_parse_bnd_query_response
- mm_telit_parse_bnd_test_response
- mm_telit_build_bnd_request
have all a long list of arguments configuring how to deal with the BND
string.
This commit reworks this list of arguments into a single new structure
"MMTelitBNDParseConfig" with the following advantages
- shorter list of arguments for the above functions
- future changes to this arguments will be transparent for the functions
above that only pass the values
- one single point where the structure is created: a new function
mm_shared_telit_get_bnd_parse_config.
When the data connection is started with AT^SWWAN, the modem expects
the DHCP discover packet from the TE while the command is running,
i.e. while the modem has not replied yet. In order to achieve that,
the bearer is marked as connected as soon as the command is
issued. This makes the NetworkManager start the DHCP process.
If the modem replies with an error, the bearer will be marked
disconnected later on.

The previously used COPS command to set to LTE-only mode did not work
for an ELS81 modem.
Now ^SXRAT is used to switch modes instead of COPS, if SXRAT is
supported by the modem.
The SAR enable operation may be selecting an explicit SAR level by
itself, so make sure the protocol implementation reports back to the
interface the default level that was used while enabling SAR.
No level change is reported in the interface if the SAR is being
disabled.
This was already forbidden in the MBIM implementation, and we should
also have it in the QMI implementation, so just make it a generic
check in the interface.
mm_iface_modem_3gpp_profile_manager_set_profile() was changed so that
the input profile object was not touched, and instead a copy of the
same would be used within the method.
Unfortunately, that change missed the update of the IP type
normalization step, which would end up modifying the original settings
instead of the newly created copy.

When processing QMI and MBIM messages to report domain registration
updates, we should do that altogether so that we don't report bogus
transitions to idle if the registration state switches from one domain
to another.

1) Not every allowed GSM7 character in UTF-8 incoding takes one
byte. Some (for example, 'à') take several bytes in input string, but
signle byte in GSM7.
2) Extended characters in GSM7 encoding take two bytes.

Get PCO information after the call is established
by using get runtime settings request

If PCO is changed we get the indication and refetch

Send the PCO info using 3gpp_update_pco_list
EM120/160 uses QCDM port for firmware updates. fwupd lists all known
ports from ModemManager and uses QCDM port to reboot the modem into
the firmware download mode.
The behavior of GRegex changed in 2.73.2 once it was ported from pcre1
to pcre2. In some cases it was made more strict, which is fine, in
other cases it exposed some change in how it behaves on certain
matches that is not extremely clear whether it's ok or not.

Either way, one thing that was assumed was that initializing all
GRegex/GMatchInfo variables to NULL and making sure they're NULL
before they're initialized by glib (especially the GMatchInfo) was a
good and safer approach.
So, whenever possible, g_autoptr() is used to cleanup the allocated
GMatchInfo/GRegex variables, and otherwise, g_clear_pointer() is used
to ensure that no free/unref is attempted unless the given variable is
not NULL, and also so that the variable is reseted to NULL after being
disposed.
Access technology and location properties are updated if modem is in
registered state.
Cache and update them when processing DSD system status indication.
Currently, supported band AT query #BND=? is failing with LM9x0 because
it expects BND 4G decimal format instead than hexadecimal.
Adding also LN920 and FN980 for completeness. They do not fail right now
because they have also "4g band extended" which format is always
hexadecimal.
