Add internal functions _nm_connection_replace_settings() and _nm_connection_new_from_hash() that cannot fail. Altough they are not public API, we have to expose them via libnm-util.ver so that they can be used from libnm-glib.

* NetworkManager; no device is connected without a #NMConnection, or

|

|

* Each #NMConnection contains a list of #NMSetting objects usually referenced
|
|
* by name (using nm_connection_get_setting_by_name()) or by type (with
|
|
* nm_connection_get_setting()). The settings describe the actual parameters
|
|
* with which the network devices are configured, including device-specific
|
|
* parameters (MTU, SSID, APN, channel, rate, etc) and IP-level parameters
|
|
* (addresses, routes, addressing methods, etc).
