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.
Looks like make targets for generating code coverage reports with LCOV
were copied from GLib but corresponding changes to configure.ac were not
made. Clean it up.
This patch increases the response timeout for the probe AT commands for
altair modems.
We've been noticing some altair modems taking upto 6 seconds to respond to the
initial probe command after a reset which results in modem-manager
timing out and sending a second probe command. The modem sends a response
after about 6 seconds for the initial probe command which modem-manager
treats as response to second probe command and this results in the
modem-manager and modem going out of sync because the modem's second
probe response is treated as response to the next initialization AT command
sent by modem-manager and so on.

Newer huawei modems, like the E3372, use the following ^GETPORTMODE response
format:
^GETPORTMODE: TYPE: WCDMA: ,pcui:1,modem:2,ncm:3,mass:4,mass_two:5,
This patch updates the parser that looks for the control TTY (pcui) and data TTY
(modem).

This facility cannot be retrieved via 'DMS UIM Get CK Status' and seems
currently unimplemented for mm-broadband-modem-qmi. The SIM enabled
status is however available via 'DMS UIM Get PIN Status'.
Using this message to add the retrieval of PIN status just after the
other facilities were queried.
Succesfully tested with Gobi2000 (05c6:9205), both retrieval of 3gpp
SIM lock status and enabling/disabling the PIN.
Bluetooth serial devices are weird. They begin life being bound with
RFCOMMCREATEDEV ioctl() and then move around the sysfs tree when they are
connected and disconnected. The connection is estabilished upon the first
open() and torn down upon last close(), their first user virtually being
"owner" of the connection. We don't want to be that process, we're only
interested in actually connected modems. However, currently we have no
knowledge of that and therefore we connect and disconnect multiple times while
probing.
This patch marks unconnected RFCOMM devices as uninteresting to us.
The actual connection and disconnection will be handled by NetworkManager.
For certain devices the name changes with their status. Notably, RFCOMM
devices move from /devices/virtual/ to underneath the HCI that is used
for the connection as the session is estabilished, and return back when
it's torn down.
My modem (Samsung GI B3740) responded "IPV4" to "CGDCONT=?". This was
not handled in mm-modem-helpers.c. The obvious fix was to return
MM_BEARER_IP_FAMILY_IPV4.
When the MBIM modem unexpectedly loses connection the port state never
gets set as disconnected thus when trying to reestablish a new
connection the bearer cannot find a port in the disconnected state.

b28230411 moved up the self->priv->forced_close = TRUE, which
caused mm_port_serial_close() to just return without actually
closing the port and cleaning up.
Also, cancel the reopen separately from closing the port since
the two operations are actually independent of each other.
