Thomas Haller b232508707 shared: add nm-secret-utils.h helper
We already had nm_free_secret() to clear the secret out
of a NUL terminated string. That works well for secrets
which are strings, it can be used with a cleanup attribute
(nm_auto_free_secret) and as a cleanup function for a
GBytes.

However, it does not work for secrets which are binary.
For those, we must also track the length of the allocated
data and clear it.

Add two new structs NMSecretPtr and NMSecretBuf to help
with that.

* SECTION:nm-setting-vpn
* @short_description: Describes connection properties for Virtual Private Networks
*
* The #NMSettingVpn object is a #NMSetting subclass that describes properties
* necessary for connection to Virtual Private Networks. NetworkManager uses
* a plugin architecture to allow easier use of new VPN types, and this
* setting abstracts the configuration for those plugins. Since the configuration
* options are only known to the VPN plugins themselves, the VPN configuration
* options are stored as key/value pairs of strings rather than GObject
* properties.
