This property will be TRUE if the bearer has the data session
connected through a multiplexed interface.
If the bearer is disconnected, or connected without multiplexing, the
property will report FALSE.
This very peculiar case can happen when an intermediate initiliazition step
of a modem fails.
The ModemManager daemon should always expose the modem interface but let not
assume that in mmcli and protect these calls.

Most older Qualcomm SoCs (e.g. MSM8916, MSM8974, ...) communicate with
the integrated modem via shared memory (SMD channels). This is similar
to QRTR on newer SoCs, but without the "network" layer. In fact, the
older SoCs also have QRTR, but the modem QMI services are not exposed
there.
The mainline Linux kernel exposes SMD channels via the "remote processor
messaging bus" (rpmsg). Through special IOCTL calls it is possible to
create a char device for a rpmsg/SMD channel. We can then use these to
send QMI/AT messages to the modem, much like the ordinary serial char
devices when using a Qualcomm modem through USB.
This commit introduces support for the new 'rpmsg' subsystem, which
allows exporting QMI-capable and AT-capable ports.
By default NO rpmsg port is flagged as candidate, it is assumed that
the plugin adding support for the rpmsg subsystem will add specific
rules to do so (e.g. so that non-modem ports are explicitly not
flagged as candidate).
All rpmsg ports will be probed for AT or QMI capabilities, unless
explicit port type hints (e.g. ID_MM_PORT_TYPE_QMI or
ID_MM_PORT_TYPE_AT_PRIMARY) are set.
These changes are highly based on the initial integration work done by
Stephan Gerhold <stephan@gerhold.net> in postmarketOS, see:

This new method allows changing the SIM slot considered as primary,
when the modem supports multiple SIM slots.
The generic handling of this method will make sure that the modem
object and all its SIM objects are re-probed from scratch as soon as a
successful SIM slot switch happens.
Implementations may report MM_CORE_ERROR_EXISTS when the switch
doesn't need to happen (e.g. if the requested SIM slot is already the
active one).
If the device supports multiple SIM slots, when the user provides a
PATH or INDEX of a SIM card to use, don't look for the SIM object only
in the 'Sim' property, also look for it in the 'SimSlots' property.
The 'SimSlots' property exposes an array of SIM object paths, with one
array item for each available SIM slot in the system. If a valid SIM
card is found in a given slot, the path of the SIM object will be
exposed in the array item; if no valid SIM card is found, the empty
object path ("/") will be exposed instead.
The 'PrimarySimSlot' property exposes which of the SIM slots available
in the system is the one configured as being primary. In a Multi-SIM
Single-Standby setup, the primary slot will be the one corresponding
to the single active SIM in the system. In a Multi-SIM Multi-Standby
setup, the primary slot will be the one configured to act as primary
(e.g. the one that will be used for the data connection) among all the
active SIM cards found.
In preparation for the multi-SIM setup, we need a way to tell whether
a given SIM card is active or not in the system.
On systems with one single SIM slot, the available SIM card will
always be active.
On Multi-SIM Single-Standby setups we may have multiple SIM slots with
multiple SIM cards, but only one of them will be active at any given
time.
On Multi-SIM Multi-Standby setups we may have multiple SIM slots with
multiple SIM cards that may be active at the same time. E.g. the QMI
protocol allows up to 5 different active SIM cards (primary,
secondary, tertiary...).
Extended the ModemManager Signal interface to include 5G signal
information for RSRP, RSRQ and SINR via libqmi. Also extended mmci
to print 5G signal info.
When we're reusing over and over the same bearer object, we can
provide statistical information about the number of connection
attempts that have been done and how many of them failed.
When a system only has one single modem, it's convenient to just look
for the first available modem or SIM object, instead of needing to
provide the full path or the exact index number.
This improvement allows users to use the "any" keyword, or any of its
substrings (e.g. "an" or even "a") to match the first available object
of the requested type.

The user may specify DBus objects in several ways, e.g. with full
object paths, just with the object numeric ids, or in some other cases
with the full device UID.
Setup one single method to process this info for all object types, so
that it's also easier to add new lookup methods for all at the same
time.

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.
The extra character size was only being applied when > 10 elements,
leaving the == 10 case out of it, so the output was being truncated.
Fix it, by using a more generic way to computing how many extra
characters we need in the size.

This new flag allows users of the API to know whether general purpose
voice calls are allowed or otherwise only voice calls to the
registered emergency numbers should be performed.
ModemManager won't really do any distinction between emergency and
non-emergency calls at this point, this flag is just an early
indication for the user of the API that no normal voice call should be
attempted.
These new methods allow querying and updating the status of the call
waiting network service, as per 3GPP TS 22.083.
The status of the service is not a property because we don't want to
unconditionally load it on every boot, given that the process involves
talking to the network (i.e. it is not a device setting).
This method will join all active and held calls into a single
multiparty call, and then request the network to terminate the call on
the subscriber's end and transfer the control of the call to the
parties that are still in the call.
This method will put the currently active call on hold, and right away
accept the next available call.
The user of the API does not need to specify explicitly which is the
next call to accept, because that is decided automatically:
* If there is any waiting call, it will accept it right away.
* If there is no waiting call but there is a held call, it will make
the held call active again.
