NMDevice rechecks available connections when the device moves to the
DISCONNECTED state, but connections are not available if the modem is
PIN locked at that time. Available connections were never re-checked
when the modem was then unlocked while in the DISCONNECTED state.
When the modem device is abruptly disconnected,
nm_modem_device_state_changed() calls deactivate_cleanup() with a NULL
device argument and that's perfectly fine.
We should only check the instance type if we know the device is non-NULL.

With this change, NMConfig is really immutable and all
modifyable parts migrated to NMConfigData.
Another advantage is that components can now subscribe to
NMConfig changes to pickup changes to no-auto-default.
No actual reloading is yet implemented. Later we will decide
on specific configuration parameters where we support reloading.
They must be then implemented one-by-one.
Some configuration parameters can be set via command line.
If a parameter is set from command line, the original value
from command line will still be preserved after reloading.
The NMConfig class should be immutable and its properties should
not change, with one exception: the NMConfigData property.
Later, when changing/reloading a configuration, NMConfig will only swap
the NMConfigData instance.
The NMConfigData instance itself is also immutable.
Make nm_config_new() usable without accessing static/singleton data.
nm_config_setup() is now used to initialize the singleton.
Still, you must not call nm_config_get() before calling
nm_config_setup() or after freeing the provided singleton
instance.
Currently the three parameters for the connectivity check (uri, interval, response)
don't get reset. Soon they might be modified at any time when reloading the
configuration.
When calling the asynchronous HTTP connectivity check, we want to
preserve the original parameters so that the result callback still can
access them later. Pass the uri and response parameter on as
ConCheckCbData.
In case of error, ibft prints an error message to stderr
with two trailing newlines. This causes multiple lines
in our logfile. Replace newlines in the error message
by whitespaces.
