We were trying to load the generic modes supported reported by either *CNTI=2 or
AT+WS46=?, so that then we could filter out the MBM-specific modes unsupported.
But, this may not be ideal, as both these two commands may fail:

Instead, we'll ask the modem for the list of modes supported, and return that
directly.
Not making them '--location-enable|disable-signal' because that's the pattern
used to enable/disable location sources. Instead, use the '--location-set-*'
pattern, as that is what we're already using for the other location setup
update.
The default setup uses a refresh time of 30s, which means that even if the GPS
location updates are received at a higher frequency, the DBus interface will
still expose at most one update every 30s.
This patch includes a new "SetGpsRefreshTime()" method in the Location
interface, which takes a single 'u' parameter, specifying the refresh rate to
use, in seconds. This method also allows 0 being passed, which will make the
implementation to publish the GPS location updates are soon as ModemManager
detects them.
Along with the new method, a "GpsRefreshTime" read-only property is exposed
to specify the refresh time in effect.
The new method and property will only be applicable if the device has GPS
capabilities.

Use the "WDS Get Packet Statistics" method to query for the ongoing number
of bytes transmitted or received. The QMI implementation uses different WDS
clients for IPv4 and IPv6; the stats reported are a combination of the values
retrieved from both WDS clients.
The new property is a dictionary which may include different parameters,
depending on what is actually supported by the underlying modem. For now,
just bytes RX/TX.
Note that this object will expose the stats *as reported by the modem*. These
values may differ from e.g. what is seen in the network interface stats.
mmcli is GPLv2+; that's what --version has always said and that's what the
README in ModemManager sources specifies:
License.
The ModemManager and mmcli binaries are both GPLv2+.
The libmm-glib library is LGPLv2+.
The CPMS test parser was expecting 3 groups (parenthesis enclosed lists) of
memory IDs, e.g.:
+CPMS: ("SM","ME"),("SM","ME"),("SM","ME")
But some modems like the Huawei MU609 may just report single elements, not
groups, e.g.:
+CPMS: "SM","SM","SM"
This patch avoids using g_strsplit() to split the groups, as that is unaware
of the possible replies without groups. Instead, a new helper method is
implemented which does the group/item split itself, considering also the
possibility of a reply with mixed groups and non-groups, like e.g.:
+CPMS: ("SM","ME"),"SM","SM"
Additionally, we also now support the case where the groups are empty, e.g.:
+CPMS: (),(),()

The XCASE terminal mode flag because is no longer specified by POSIX
and has no effect on linux. Because of the latter fact we can remove
it. This fixes a compilation error with musl libc.
. A shift has undefined behaviour if the mathematical result
(lhs * 2^{rhs}) doesn't fit in the range of the resulting type.
In other words, you can't left shift into the sign bit of a
signed integer type.
The error message is:
mm-broadband-modem.c:3308:15: runtime error: left shift of 1 by 31 places cannot be represented in type 'int'
SUMMARY: AddressSanitizer: undefined-behavior mm-broadband-modem.c:3308:15 in
Auth settings will be added in a QMI message only if at least one of these is
requested:
* An explicit auth preference is requested.
* User string is given and isn't empty.
* Password string is given and isn't empty.
Given that the Location interface requires 3GPP info reported by the 3GPP
interface, we should only trigger registration checks once the Location
interface has been already enabled and ready to be used. If we don't do this,
we'll end up e.g. getting initial MCCMNC values but never reaching the Location
interface properly.
So, fix this by triggering all registration checks (CDMA and 3GPP) only after
having enabled all interfaces.
LAC/CID may only be given in the serving system indications when the values
change, and therefore we shouldn't reset the values to 0 whenever they're not
reported.
This seems to happen in newer devices; older devices like the MC7710 did always
report the values in the indications.
This check makes no sense. We're converting from a ModemManager enum to a QMI
enum, nothing else; i.e. 'caps' is *not* the current capabilities of the modem.
Variability in the response style from certain modems causes the parsing
of the +CGMR response to fail. For example, the Telit HE910 inserts an
empty string ("") in the second field of the response, causing the
sscanf implementation to fail.
This patch converts the parsing of the CGMR response to a regex that
allows for more flexibility and robustness, and adds unit tests around
the parsing call.
