Different ports of the same modem may get handled by different drivers. We
therefore need to provide a list of drivers (new `Modem.Drivers' property with
signature 'as') instead of just one (removed `Modem.Driver' property with
signature 's').
$ sudo mmcli -m 0 | grep drivers
| drivers: 'qcserial, qmi_wwan'

gsm: fix sending SMS messages on some modems and use PDU by default
It turns out we really do have to wait for the modem to return the
">" prompt before sending the message data, otherwise a number of
modems will complain about the data and fail the message. Fix that
by sending the first bit of the CMGS, waiting for the ">", and then
sending the rest.
This also switches all modems over to PDU mode by default if they
support it, since it's more compatible and most recent modems don't
even bother to support text mode anyway.
Instead of using a predefined set of string values for 'ip-type' in
Modem.CreateBearer() and Simple.Connect(), we'll use an enumeration. The
implementation will then need to convert the requested IP family type to e.g.
the correct PDP type in 3GPP modems.
This change also consolidates the use of enums in dictionary properties when
possible to do so, as with the Rm Protocol.
Plugins may specify that specific vendor & product IDs or strings are not
supported. This is useful when plugins need to specify that they support
all devices of a given vendor except for some specific ones.
In practice, it may take longer time for a SIM to become ready when the
modem interface tries to use AT+CPIN? to determine if the SIM is
PIN-locked. This patch increases the number of trials for PIN check to
address the issue.
Once upon a time it was a good idea to have separate steps for CS and PS related
actions, so that plugins could override specific steps with a great detail. That
idea turned out to be not very useful, as the only case which requires custom
CS/PS registration actions is the QMI-enabled modem, and that one has commands
to act on both registration actions at the same time. So, we now consolidate
all steps, so that the implementation of the interface needs to provide all the
logic to setup/enable/disable/cleanup/check registrations in each mode.
Also, we consolidate how the unsolicited registration messages are handled, so
that it's equivalent to other unsolicited messages:
* 'Setup' will configure ports to process the unsolicited messages.
* 'Enable' will tell the modem to send unsolicited messages.
* 'Disable' will tell the modem not to send unsolicited messages.
* 'Cleanup will configure ports to ignore the unsolicited messages.
The previous logic would first request to check if indicators were supported,
and only then allow to setup/enable/cleanup/disable unsolicited events. This
behaviour is very specific to the generic 3GPP case, and therefore it shouldn't
be handled in the even more generic 3GPP interface. The logic is still kept,
but handled within the MMBroadbandModem object.
If a port support task was deferred until suggested, do not assume that the
suggested plugin actually supports the port, instead re-launch support check.
This covers the cases where a net port appears in a modem which only supports
AT ports (e.g. Nokia case).
Instead of hardcoding the logic to decide which ports are open or closed in the
different steps, we now let the subclasses of MMBroadbandModem to do that
themselves.
We now provide:
* initialization_started() and initialization_stopped(): the generic
implementation does the serial port open/close in these steps.
* enabling_started(): the generic implementation does the serial port opening
here. The serial ports are kept open as long the modem is in enabled state.
* disabling_stopped(): the generic implementation does the serial port closing
here.
Instead of providing a method to get if a plugin is requesting to get sorted
last, we provide a way to comparing two plugins, compatible with the
GCompareFunc required in g_list_sort().
