If the ModemManager is stopped via '/etc/init.d/modemmanager', mmcli calls
always remain in the process list. This is because the ModemManager-monitor
call is not terminated properly, as the kill signals are not handled
correctly in the startup script for mmcli.
To fix this, the signal handling is refactored.

The default 'timeout' value is 30 seconds when calling an mmcli action. That
is too long. For this reason, the mmcli 'timeout' option is specified for
calls and the value is set to 10 seconds.

This change introduces an optional configuration
of the netifd integration in the ModemManager package.
When disabled, it removes the NETIFD dependency and
other unwanted components from the root filesystem
during the build phase.
Additionally, in the modemmanager.common the netifd-proto.sh
inclusion line can be savely removed as there is no usage
of it in its functions.

If the modem loses the connection, an attempt is made to re-establish the
connection via the report-down script.
Until now, the modem was disabled when the modem processed the teardown of
the modemmanager protohandler. The immediate up events of netifd renables
the modem right away. This takes time, which is not necessary.
This commit changes the behavior so that the modem is not disabled when
the modemmanager is disconnected via the report-down script.

After the SIM has been successfully unlocked, it is initialized. This can
take longer on some modems, so we must wait until the modem is ready to
execute the next commands.
Otherwise the modem cannot be enabled and aborts with the following
error message:
error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.WrongState: modem in initializing state'

If a configured 'plmn' is deleted from the configuration between a connection
setup, it will continue to be used because the modem remembers it.
Therefore, the 'plmn' stored in the modem must be deleted when a new
connection is established if it is no longer in the configuration.

In the current implementation of the modemmanager 'proto', if a 'plmn' and a
'technology' is configured, the 'plmn' is set first and then second the
'technology' on a 'proto' setup.
However, this is problematic if a 'technology' has already been set in an
earlier run. It is possible, that this previously set 'technology' is not
available at the current location, as the modem remembers the setting.
To fix this, first set the technology and then the plmn.

If the ModemManager is started with debug, all outputs are written to the
system log. To simplify debugging, a logging file is now created under
'/var/log/mm.log' in this case. This simplifies error analysis.

This new check in the proto modemanager prevents the SIM card from being
blocked and therefore PUK is not required. If the PIN is entered incorrectly
in the 'uci' configuration, it makes no sense to try this several times
until the PUK is required. Should it nevertheless happen that the PUK
is required, then this will logged.

The variable interface is used in the sub-function 'modemmanager_check_state'.
However, this is not an argument of the function and so the global value
is used. Addding the variable as an function call argument fixes this.

This commit improves the automatic reconnect logic. If the modem cannot
establish a connection, for example due to poor reception, the
proto_block_restart prevents the interface from trying to reconnect.
To enforce the connection, this commit adds a new option that allows the
system to attempt to establish a connection indefinitely.

There are situation for mobile routers, that the modemmanager can not
stay connected to the mobile network. There can have various reasons.
In order for the system to reconnect automatically, the netifd must be
informed that it must re-establish the connection.
The modem manager already does have a script callback handling which is
already used by the modemmanager in openwrt. Currently the modem is marked
as not unavailable when a disconnected event is detected.
The behavior was changed with this commit, so that a reconnect of the
interface is now triggerd via the netifd if the modem disconnects.

If a 'plmn' is set in the configuration, a registration attempt should be
established before the simple-connect command. If the plmn is set during
the simple-connect, a network change may occur during the connection setup.
To prevent this, the registration is started before the simple-connect with
a separate mmcli command. So that we can be sure that the modem is already
registered in the correct network before the simple-connect command.

Before this change, the status of the sysfs paths from the kernel events
was cached with a cache file. This is necessary to mark configured modems
as available for the netifd.
Using the new monitor service via the mmcli command 'mmcli -M' simplifies
the whole process. There is no need to start sub shells in the background
anymore that monitors whether the modem has already been added to the
ModemManager.
For this purpose, a new service was added that reacts on add and remove
events for modems in the ModemManager and, if necessary, marks the logical
netifd interface as available.

The modem saves the permitted technology configuration in the modem
itself. If the technology configuration is deleted in the uci, this is
not passed on to the modem. This means that the previously saved
technology configuration is remains in the modem and is therefore still
active. By setting the technology to 'any', if no option is set, all
technologies are allowed again.

If no GSM but only 4G is available and a special APN must be used, it
is necessary to set an inital EPS bearer beforehand. If this is not set,
then modem cannot log in and register in the mobile network.
The new option 'init_epsbearer' could be set to the following options.
* none: No init EPS bearer is used and the old one is deleted (default)
* default: Use init EPS bearer with the following config options
'iptype', 'allowedauth', 'password', 'user' and 'apn' as for the
connection bearer.
* custom: Other parameters are used that do not match those of the
default connection bearer. These have an 'init_' prefix and are named
in the same way as the default connection bearer config options.

If the ModemManager process crashes, the interfaces are not cleaned
up properly because the stop_service method is not called. With this
change, the interfaces are cleaned up both when stopping the service
and during a crash. Therefore it is no longer necessary to perform a
cleanup at the beginning.
