SBUS: Start implementing property access

This patch adds the basis of SBUS getters and setters. A new module,
sssd_dbus_properties.c would contain handlers for the property methods
like Get, Set and GetAll.

Type-safe property access works in a similar fashion like type-safe
method calls - the invoker calls the getter which returns the primitive
type, which is in turn marshalled into variant by the invoker.

This patch does not contain the complete functionality, see later
patches that continue implementing the getters and setters.
