Some quectel devices, like the EC25 have a non-standard additional '3'
mode value:
0: Disable automatic time zone update via NITZ
1: Enable automatic time zone update via NITZ
3: Enable automatic time zone update via NITZ and update LOCAL time to RTC
The autoconf macros AX_COMPILER_FLAGS_{CFLAGS|GIR|LDFLAGS} test
for compiler and linker support of various flags, and add the flags to
the generated output.
If the command-line option '--enable-compile-warnings' is specified to
'configure', a number of additional warning options is also added to the
output. This is the default.
This update requires the presence of the GNU autoconf-archive in the
system.
And added support for several new things, including:
* Setting "any" band now attempts to set all supported bands.
* Added new 2G band value '5' (egsm+dcs+pcs+g850).
* Setup support for two different 3G band combinations, a default one
plus an alternate one applicable to the LM940/960 models only. The
alternate combination is selected via udev tags.
During the refactor, the following Telit-specific helpers were also
removed and exchanged with more generic counterparts.
* mm_telit_bands_contains() -> mm_common_bands_garray_lookup()
* mm_telit_get_band_flags_from_string() -> mm_parse_uint_list()
Devices like the Netgear AC313U require explicit context monitoring,
otherwise the device may end up disconnected internally and MM would
still think that the connection is ongoing.
The DW5821E module is managed in MBIM mode by default, and exposes a
NMEA capable tty in USB interface #4.
Enabling/disabling the NMEA output via the TTY is done with AT
commands, so this implementation requires also a valid AT port in the
system.
Given that the AT commands used to enable/disable this feature are
based on modifying non-volatile memory through AT^NV, this
implementation is very specific to the DW5821E. If we're able to do
the same on other Dell modules in the future, we'll just rename the
new object to a more generic one.
Implement a new interface to keep the code shared between the QMI and
non-QMI modem implementations.
While doing that, also fix the parent interface pointer handling, so
that it isn't a static pointer applicable to all modems, and make it a
per-modem specific pointer. Without this fix, ModemManager would crash
if e.g. running with both a QMI and non-QMI Cinterion modem at the
same time.
The new shared Cinterion logic will be in charge of managing all GPS
sources not already managed by the parent interface. E.g. if the
parent implementation already supports QMI-based GPS location (using
the LOC service for example) prefer that to the custom AT-based
logic.
The Netgear AC341U seems to delay reporting packet service status
indications or actually not even send them. This leaves us with modems
in connected state in ModemManager but actually disconnected. We can
detect this situation by actively polling ourselves the connection
status.
See e.g. this case where the indication is received 2.5 mins after the
first OutOfCall error detected when loading statistics.

The TOBY-L4 exposes multiple TTY ports, but each of them has different
purposes:
The TTY at interface #2 is a fully capable AT port but shouldn't be
used to start connections, so we flag it as secondary.
The TTY at interface #4 is a non-AT debug port, so we explicitly
ignore it to make probing faster.
The TTY at interface #6 is the fully capable AT port that must be used
as primary port.
The TTY at interface #8 is an AT-capable port but dedicated to FOTA
update operations.
