The NWSTATE field reports both available access technology and the
actual access technology in-use when a PS connection is active, so
report the actual access tech when it's available.
For connection failures, get additional error detail. Currently,
the only error codes that are mapped are the 3GPP TS 24.008 codes
for "Unknown or missing access point name" and "Requested service
option not subscribed" (which is sometimes returned for an invalid
APN).
(random fixes and cleanups by dcbw)
We need to ensure that the supports task always has the results of the probing,
no matter if the probing was just launched by the plugin grabbing the port, or
by a previous plugin. We do this during supports_port(), by propagating to the
supports task any possible previously cached probing results.
This is because the cinterion plugin can handle RS232 modes, and checking
support for them needs to have the vendor ID probed with AT commands, so
probing is almost always issued in this plugin. By sorting last, we let
other plugins check support first.
This feature is initially disabled for all modems, but plugins can enable it by
setting a value greater than 0 for the "max-timeouts" property when creating the
modem object.
Note that even if a plugin says it wants to be sorted last, the generic plugin
will always be the last one. Also, there is no order guaranteed between two
plugins that request to be sorted last.
Port probing is extended to also query for Vendor ID and Product ID. This allows
plugins to check whether the reported IDs are expected, and thus we enable
plugins to handle modems connected via RS232 ports (where udev doesn't give any
vendor ID) or modems connected via a USB adapter (where udev gives the vendor ID
of the adapter).
Note that this effectively means that a plugin which expects these kind of modem
connections will end up always launching port probing as they won't only rely on
the vendor ID reported by udev.
We try to look for 'psinfo' indication in AT^SIND? output (available in 3G
devices from Cinterion), and if that is not available, we try to use the
AT^SMONG GPRS monitor (available in 2G devices from Cinterion).
Same USB IDs as the X060s which is driven by Longcheer, but uses the
X22X command set so we have to do a little dance and make sure we
don't claim the X060s here.
The X200 shares the same USB VID and PID as the X060s but the X200
does not use the same AT command set; it uses the X22X plugin
instead. Since both modems also report the same +GMM and +GMI
responses, we have to fall back to using +GMR even though that's
a pretty sketchy way to tell them apart if the firmware ever changes.
Previously plugins could only stop probing, *or* stop probing and
indicate support for a device. For the Alcatel X200/X060s debacle
we need to stop probing and indicate that the plugin does not
support the device at all.
Implemented using a custom invoke method which doesn't call the callback, and
instead calls parent disable passing the callback as argument.
This fix ensures that if a modem gets removed, no invalid modem reference is
passed to the parent disable, as info->modem would be set to NULL and we can
detect it in the custom invoke method.

dbus-send --system --dest=org.freedesktop.ModemManager --print-reply /org/freedesktop/ModemManager/Modems/0 org.freedesktop.ModemManager.Modem.Gsm.Card.GetSpn

Split the Samsung initialization sequence from "ATZ E0 V1" to "ATZ"
and "ATE0 V1" - the modem is allowed to ignore the rest of the line
after Z, so echoing was not being turned off, leading to getting
"AT+CIMI\n\n" as part of the IMSI when it is retrieved at startup.
