This signal indicates that the port is no longer accessible. Unlike a
udev port removal event, this indication may happen even if the port
is still exposed by the system.
It is designed to detect protocol proxy crashes, and so when such
event is detected by the modem, a full reprobe of the device will be
done to start from scratch the protocol management operations.

The mm_base_modem_grab_port() now receives a MMKernelDevice directly from the
plugin, which is then stored in the MMPort corresponding to the port.
This means that we have direct access to e.g. all properties set by udev rules
everywhere, and we don't need additional GUdevClient objects (e.g. like the one
used in the Huawei plugin to detect NDISDUP support during runtime).
For virtual ports (e.g. generated during unit tests), we have a new 'generic'
kernel device object which just provides the values from the kernel device
properties given during its creation.

A constructor cannot return NULL, specially when there are subclasses, as it
would segfault. Just remove it, as it doesn't really do anything useful.

It is no longer used since commit 736aa0d2d.

Make port roles more flexible. We have modems that do PPP
on interfaces other than the primary interface, and that
wasn't possible with the old code. So clean up all that
logic and move the port organization code into the core
so we can reduce code in the plugins.
In the new world order, the plugins say whether the port
is a QCDM port, an AT port, or ignored. If it's an AT
port the plugins get to tag it as primary, secondary, or
PPP, or any combination of the 3. This allows for modems
where PPP should really be done on the secondary port
(Huawei E220, Sierra devices) so that the primary port
stays open for command and status.
Modem subclasses no longer get asked to handle port grabbing
themselves. Instead, that's now done by the generic classes
(MMGenericCdma and MMGenericGsm) and the plugins are notified
when a port is grabbed so they can add unsolicited response
handlers for it. After all ports are grabbed by the generic
classes, they get "organized", which assigns various ports
to the roles of PRIMARY, SECONDARY, DATA, and QCDM based
on specific rules and hints that the plugin provided (which
are expressed as MMAtPortFlags). The plugins then have
a chance to perform fixups on the primary port if they choose.
The plugin code is responsible for determining the port
hints (ie MMAtPortFlags) at probe time, instead of having
a combination of the plugin and the modem class do the
job. This simplifies things greatly for the plugins at
the expense of more complicated logic in the core.

Isn't really needed since it's just the same as any other net
device port type.

Make it more flexible, add logging to a file, and absolute and
relative timestamps.

So many modems just don't implement carrier detect that it makes
the previous 'connected' logic useless, so base it off connect/disconnect
and fix up a few places that didn't check connect status before
trying to send commands. Also ensure the serial port is unlocked
for PPP to use when connected.

Create a base MMPort class to handle both tty and net ports generically,
and move plugins over to that. Also port the 'hso' plugin to udev.
