This will make it slightly easier to port mm_port_serial_at_command() to
use GTask, since we won't have to keep a pointer to the result in GTask
after _finish() has been called.
In most cases the caller needs the value anyway, so this doesn't add too
much hasle.
The Cinterion plugin is using the output of the SQPORT? to guess which
ports can be used for AT commands and data connection.
Yet at the same time the udev adds port type hints to the Cinterion
modem upon its discovery.
This commit changes the initialization in a way that from now on it
skips sending SQPORT? when the port type hints are already assigned. By
doing this we make sure that the udev port type hints are being used
when they are available. In case they are not the initialization relies
on the outout of SQPORT? as it did do far.

GError structure may not be initialized after execution of
mm_3gpp_parse_cgdcont_read_response() and accessing it's
fields will cause a segmentation fault.
When Telit FN990 is integrated through PCIe, but also USB lines are
available, ModemManager will consider the port on the USB composition
as a different modem:
oem@sw-test:~$ mmcli -L
/org/freedesktop/ModemManager1/Modem/1 [telit] FN990A40
/org/freedesktop/ModemManager1/Modem/0 [Telit] FN990A40
oem@sw-test:~$ mmcli -m 0

Ignore composition 0x1075, since it should not be used by ModemManager
and can only show when PCIe is used.
Some firmware versions return an empty string for the revision when
using the device caps MBIM request, so use AT commands as a fallback
in case this happens.
Instead of creating libmm-plugin* and libmm-shared* libraries that are
dlopen()-ed on runtime, allow incorporating all plugins into the
daemon binary itself.
This makes the startup of the daemon much faster and also avoids
issues with builds that require linker namespace isolation.
Fixes https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/674
We are going to allow including the plugin sources built within the
ModemManager daemon binary; moving the sources within the daemon
sources directory makes it easier.
