Currently, Telit's SIM swap implementation is stateless and
based on #QSS unsolicited messages 0/1 (SIM_REMOVED/SIM_INSERTED).
However, the user might have configured the modem in order to provide a
more detailed information, with #QSS values 2/3 (SIM UNLOCKED/SIM READY).
In this case and with current implementation, even receiving "#QSS: 3" will
trigger the "SIM swap" logic. The same issue might occur in other use cases
too, i.e. with SIM locked or when the message is received from both USB
ports.
This patch makes SIM swap implementation stateful, and it considers as an
actual SIM swap, only transitions from #QSS: 0 to #QSS: 1/2/3 and vice
versa.
Commit f9c63bfa0 "build,plugins: update build rules" accidentally
changed the Novatel LTE plugin from 'libmm-plugins-novatel-lte.so' to
'libmm-plugins-novatel_lte.so'. The name becomes inconsistent with other
plugin names.
Instead of relying on the udev daemon and GUDev to manage the devices reported
by the kernel, we can now run ModemManager relying solely on the kernel events
reported via the new ReportKernelEvent() API. Therefore, the '--no-auto-scan'
option is implicit for the ModemManager daemon when udev is disabled in the
build.
Additionally, a new custom implementation of the kernel device object is
provided, which uses sysfs to load the properties and attributes required in
each kernel device, instead of using a GUdevDevice.
The udev rule files are kept in place, and a simple custom parser is provided
which preloads all rules in memory once and then applies them to the different
kernel objects reported via ReportKernelEvent(), e.g. to set port type hints.
A simple unit test setup is prepared to validate the udev rules during the
`check' Makefile target.
Instead of relying constantly on GUdevDevice objects reported by GUdev, we now
use a new generic object (MMKernelDevice) for which we provide an initial GUdev
based backend.
We try to combine in common envvars the compiler and linker flags shared by the
different components, and where possible, also re-using the implicit AM_CFLAGS
and AM_LDFLAGS variables that automake provides, and which apply to all objects
being built in the same Makefile.am.
The plugins build rules are also updated so that whenever a plugin has some
testable 'helpers', these are compiled into a noinst library and then the new
library included by both the plugin and the tester program. This avoids multiple
recompilations of the same sources for different objects.

There's no real need for a custom Gobi plugin any more. All the vendor-specific
Gobi-powered modems should be handled by vendor-provided plugins supporting QMI
modems; or otherwise, as a last resort, by the generic plugin.
For Dell-branded Novatel, Sierra and Ericsson modems.
The Novatel plugin will no longer accept every Dell-branded modem, which was
the current situation. Instead, a new Dell plugin will take care of probing for
the correct vendor string, and based on the results create a specific Novatel,
Sierra or Ericsson modem.
In order to properly support this, the Novatel, Sierra and MBM plugins now
export their implementations into non-inst libraries that the Dell plugin will
import.
Also, for now, the Dell plugin doesn't make any difference between e.g. Sierra
or Ericsson MBIM implementations, just a generic MBIM modem is created in both
cases, as that is anyway what the Ericsson MBM and Sierra plugins do already.

In short:
* The 'sierra-legacy' plugin will handle all the old AT based modems,
including the DirectIP ones. This plugin is filtered by driver ('sierra' or
'sierra_net') and forbidden-drivers ('qmi_wwan' and 'cdc_mbim'). This plugin
should also grab HP and AT&T branded models if they are handled by the
proper kernel driver.
* The 'sierra' plugin will only handle QMI or MBIM based Sierra modems, which
are really all the new ones. This plugin is filtered by VID (0x1199) and
driver (qmi_wwan and cdc_mbim).
For this separation to work, the 'sierra' and 'sierra_net' plugins need to be
complementary to each other.
Build all targets, except for CLI tools (mmcli, uml290), with special
flags needed for collecting code coverage information when the build has
been configured with --enable-code-coverage.
Three new targets are available in the top build directory:
- `check-code-coverage' runs the test suite and generates a code
coverage report,
- `code-coverage-capture' generates a code coverage report from already
collected data, which can come in handy when one wants to see code
paths touched by a particular test,
- `code-coverage-clean' removes the collected coverage data and the
generated reports.
The PHS8 in QMI-mode doesn't support GPS location retrieval via QMI, so we will
fallback to use the AT-based setup and the TTY for reading NMEA traces.
Split out the %IPDPADDR parsing into a helper and add testcases for it,
and add support for IPv6 handling. If the returned IPv6 is link-local,
the address should be assigned to the interface and SLAAC performed to
retrieve the actual IPv6 prefix and RDNSS/DNSSD information.
This patch uses the extended error code after a registration failure to
determine if the SIM in the relevant modem is associated with a non-provisioned
account. It uses the standard AT+CEER command, but the implementation is
restricted to the altair plugin.
