Adding dynamic port identification for Telit modems that support AT#PORTCFG
command. Port configurations for HE910/UE910/UL865 taken from document
"HE910/UE910/UL865 Families Ports Arrangements User Guide"
If for any reason the modem is in OFF state and still can talk to the modem,
allow running the remaining transition requests to LOW or ON. This can happen
for example for modems that use CFUN:0, i.e. which can still go online with
CFUN=1.

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.
We really do need a wait time to make sure most ports are exposed by the
kernel, so that plugin filters based on "forbidden-drivers" work correctly. E.g.
the "gobi" plugin now flags as forbidden the "qmi_wwan" driver, which means that
modems exposing both TTYs and QMI/WWAN ports should never be handled by the Gobi
plugin.
The new tester allows to play with the AT-capable TTY using the same code as
ModemManager itself.

Some new devices, like the Dell DW5770, will return an internal error when
trying to bring the power mode to online. We can avoid this by sending the
magic "DMS Set FCC Auth" message before retrying.
Bumping libqmi version to 1.13.4, which is the one that supports this new
message.

MM probing appears to make 'visor' module die; and anyway
most of the devices driven by 'visor' are not phones, and
of the 3 that are phones they are so old (2002 - 2005 era)
that nobody is likely using them for dialup anymore.

Since commit 2d700043ab ("core: use g_unix_signal_add() for more
reliable Unix signal handling") we no longer have to stick to
signal-safe functions in the SIGTERM/SIGINT handler.
Use exit() to terminate so that the clean-up functions are ran and code
coverage data gets written into files.
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.
