We also remove the explicit refresh request from the Cinterion plugin,
as this is a generic action applicable to all modems that require
polling for signal quality and/or access technology.
Plugins have two ways to update signal quality and access technology
values: via unsolicited messages or via polling periodically.
Instead of keeping separate contexts for polling signal quality and
access technology values, we setup a common timeout to trigger
both. This allows us to simplify in which case the explicit update is
required, whenever one is needed to be explicitly updated, the other
one should also be.
The logic now also allows plugins to return an UNSUPPORTED error in
either load_signal_quality() and/or load_access_technologies() to tell
the interface logic that the polling of the specific item shouldn't be
performed (e.g. if the updates are expected via unsolicited messages).
If both signal quality and access technology polling is flagged as
disabled, we totally disable the polling logic internally.
The new SignalCheckContext is bound to the lifetime of the object so
that we can keep the value of the supported flags until the object is
destroyed.
If going directly e.g. from "Searching" to "Connecting", just setup
the signal quality retrieval logic right away, don't assume we always
go through "Registered" state before starting a connection.

If a device reports "LTE" in the list of current capabilities, we'll
set EPS network supported by default. This will enable CEREG
registration checks for AT based devices.
If a device reports only "LTE" in the list of current capabilities, we
disable all the other network support flags (e.g. will disable CREG
and CGREG checks among others).

BaseModem
added reprobe property.
MMDevice
added logic to recreate the modem if it is set invalid and "to reprobe"
MMBroadbandModem
* added initialization step for SIM hot swap:
1. keep dedicated ports open to listen to modem's unsolicited
2. dedicated error management in case of initialization failure due to SIM missing
* added function to be called in order to act upon SIM insertion/removal:
1. close dedicated ports
2. set the modem to be reprobed
3. disable modem
* added SIM HOT SWAP boolean property
MMIfaceModem
* added initialization step for SIM hot swap, if supported by the plugin
* dedicated error management in case of initialization failure due to SIM missing
Inverted steps UPDATE_LOCK_INFO_CONTEXT_STEP_RETRIES and
UPDATE_LOCK_INFO_CONTEXT_STEP_AFTER_UNLOCK.
Soon after the unlock, the SIM can be busy and
loading unlock retries might fail.
When implemented, let run "after unlock" logic before any other step in
update lock info, when SIM is not locked this change does not have any
effect since "after unlock" is not executed.
The mm_iface_modem_is_*_only() checks were validating that all the other
capabilities except for the ones being queried were unset, but the check wasn't
explicitly checking that the actual capabilities being queried were set.
This was making the check fail when capabilities == MM_MODEM_CAPABILITY_NONE.

When passing known_lock=UNKNOWN to mm_iface_modem_update_lock_info()
we actually do want to ask the modem itself for locks instead of
checking the cache. For example, when an unknown error is returned
after performing PIN/PUK operations, the cache value may well be
NONE if that was the prior lock state, and that bypasses the modem
which might now be locked. Thus the state gets messed up.
Reproducer is to send 'ChangePin' with the wrong "old" PIN 3 times,
then send a wrong PUK. No error was returned from mmcli and
the modem's lock state was shown as 'none'.
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.

We have a report of a modem that switches access technologies frequently,
in this case almost every 10 seconds. While that's unusual, it's not
unexpected depending on the RF environment. We shouldn't spam syslog
with that info; if we need it we can get it with mmcli.
There are systems in which the modem power source can be controlled externally,
e.g. to switch it on or off. In these cases, it is sometimes advisable to be
able to tell the modem to cleanly shut off completely before the power is cut.
So, allow transitioning to the OFF power state if the modem supports it, even if
afterwards the modem could be completely unreachable.
When wait_for_final_state_context_complete_and_free is invoked, if the callback
associated with the GSimpleAsyncResult object of the WaitForFinalStateContext
object updates the modem state via mm_iface_modem_update_state, state_changed
is invoked, which causes wait_for_final_state_context_complete_and_free to be
invoked again on the same WaitForFinalStateContext object. That leads to the
following crash, which is observed sometimes when a modem is being disabled.

This patch removes an unnecessary G_SIMPLE_ASYNC_RESULT() cast of the
'result' field, which is already of type GSimpleAsyncResult, of
InternalLoadUnlockRequiredContext.
The new internal_load_unlock_required() method will take care of running the
subclassed load_unlock_required(), if available, and also retry the check up
to 6 times.
This method will be used both by the standard unlock required check and by the
check within the current capabilities loading for multimode devices.
This patch fixes an assertion failure 'ctx->fatal_error == NULL' in
initialization_context_complete_and_free(), which happens if
'fatal_error' of the initialization context is set during the modem
interface initialization and the initialization is later cancelled.
We will expose a new 'Ports' property listing all ports currently known by a
given modem. Ports which are not used but are detected as being part of the
modem will be listed with an 'unknown' port type.
This change uses the new 'MMModemPortType' enum and the new 'MMModemPortInfo'
helper struct to handle these values in libmm-glib. The already available
'MMPortType' enum hasn't been re-used for the interface because it contains
values that we don't need (e.g. IGNORED).
The port list is now also included in the modem information command of mmcli:
$ sudo mmcli -m 0
/org/freedesktop/ModemManager1/Modem/0 (device id '97b7b99e3e2bea103880545b619fb05a3cc81b26')
-------------------------
System | device: '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4'
| drivers: 'qcserial, qmi_wwan'
| plugin: 'Gobi'
| primary port: 'cdc-wdm0'
| ports: 'ttyUSB0 (qcdm), ttyUSB1 (at), cdc-wdm0 (qmi), wwp0s29u1u4 (net)'

The real power state value of the modem may be changed by other means, e.g.
rfkill. So when changing power state of the modem in MM, we better recheck
which the current power status is.
A better full approach would be to follow rfkill changes, but this fix should
help until that is done.
https://bugzilla.gnome.org/show_bug.cgi?id=702838
And also make it a list of masks, specifying which are the specific combinations
supported, not just one mask with all.
E.g.:
-------------------------
Hardware | manufacturer: 'Sierra Wireless, Incorporated'
| model: 'MC7710'
| revision: 'SWI9200X_03.05.19.04ap r5475 carmd-en-10527 2012/09/17 17:57:14'
| supported: 'gsm-umts
| gsm-umts, lte'
| current: 'gsm-umts, lte'
| equipment id: '358178040668164'
We now have a single 'CurrentModes' property which contains both values in a
tuple with signature "(uu)".
Also, rename 'SetAllowedModes()' to 'SetCurrentModes()', and update the list of
arguments expected to have a single "(uu)" tuple.
You can't g_array_insert_val() to an index that's beyond the end
of the array, which was happening if the user tried to set the
band list to "any":
mmcli -m 0 --set-bands=any
Just use g_array_append_val() instead.

We don't support SIM/RUIM on CDMA devices (yet), so for now it makes
no sense to run the after-sim-unlock step on CDMA-only devices where
a SIM won't be present.
Unfortunately we don't know at this point whether there is a SIM
or not, so if the modem is a multi-mode device (implying it has a SIM
slot) and its plugin implements the modem_after_sim_unlock() hook,
the hook will still be executed and might cause an unecessary delay
when a SIM is not inserted.
