The original code for xmm7360_byte_array_read_asn_int() returned
signed integers both from the function and from the returned
Xmm7360RpcMsgArg, but didn't handle sign extension on the
value returned from the function. That would lead to different
values between the function return and the Xmm7360RpcMsgArg
value, which seems wrong.
Make those two correspond and add checks in various places that
shouldn't ever see negative ints.

That way UNKNOWN is the zero'd value instead of BYTE; it's easier
to test for and less error-prone if not explicitly set to the right
value.

xmm7360_byte_array_read_asn_int() would keep bit-shifting a gint into
oblivion if the int's size was > 32-bit. It also didn't handle size 0
ints at all, and while size 24 ints would get stuffed into a 32-bit
variable those probably aren't a thing and if they actually are they
should get specifically handled.

So we can unit-test all the parsing and building code more easily
without having to link to a bunch of serial port stuff.

If the error matches, then a `+CIMI` command is sent to the device and
processing continues. However, the current error (for the `+CPIN?` command)
is not freed or propagated, fix that.

The MTK specific modem object should be included in the 'mtk' shared

Current cell broadcast messages from missile warnings in Israel
have an addition `00` at the end to pad for an even byte number.
This breaks conversion making the whole message fail conversion. As this
is a 15 part message in 3 languages the whole notification is lost in
this case.
Try harder to convert the message and recover even partial bits.

To be able to have quick position fix GNSS engine needs to know
- predicted orbits data,
- current time,
- approximate position.
Modem sends indications with requests, when it needs corresponding
information. Predicted orbits can be injected using
'mmcli -m any --location-inject-assistance-data=<file>'. But to
accelerate time to first fix after cold start extra information is
needed like time and coarse position.
Inject position requests are received, when GPS session is initiated
using QMI_LOC_START. In inject position request modem sends
information about its last known position. If last known position is
zero, when this is a cold start and inject position is needed to
improve TTFF.
Last position from the modem is cached in ModemManager and is injected
next time, when modem requests it. For example, if modem is restarted.
When timestamp on injected position is too old, than position is
ignored and location engine does cold start. Therefore current time is
used for injected position.
When injected position is far away the actual one (for example, after
flight), after some time location engine falls back to cold start.
Tested on Quectel EG25-G.

This class allows to preserve cached position across ModemManager restarts.
Cached location can be used to improve time to first fix after device
start by injecting coarse position into location engine. Since there
wasn't any fix yet, position in ModemManager is unknown. To fix this
cached location is saved on disk (/var/lib/ModemManager/location.ini)
when location session is stopped or ModemManager is stopped and loaded
on the next start from the file.
install_emptydir is introduced in meson 0.60.
Distributions has to create directory to store cached location in
packaging, because ModemManager runs under systemd isolation with
limited rights and it can't create this directory by itself.

Qualcomm suggests to use mux id values >= 0x81: though this does not
seem a strict mandatory rule, there are scenarios in which the usage of
a specifix mux id is required otherwise various kind of issues could
happen (e.g. call failure, limited throughput...).
A new ID_MM_INITIAL_QMAP_MUX_ID udev tag allows setting the first initial
mux id value to be used when creating the multiplexed data connection.
