SBUS: Use default GetAll invoker if none is set It is alright for an interface to not have any GetAll invoker set if it doesn't have any properties, but we still want to return an empty message. Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

sbus: use hard coded getters instead of generated Properties are single value of a small number of predefined D-Bus types. There is no need to generate them with codegen. Actually, the source generator for property getters is already quite mess with branching for array, strings and object paths. Adding any more complex type in the future (such as dictionary) would require even more branching or creating a separate path for it. Hard coding the getters will simplify creating new ones for more complex types. This patch also reduces lots of code duplication and creates a simple function for GetAll.

SBUS: Implement org.freedesktop.DBus.Properties.GetAll for primitive types This patch implements the GetAll method of the org.freedesktop.DBus.Properties interface by iterating over the available getters and putting all the results into a single getter. The patch includes a unit test that exercies all currently supported array types. Reviewed-by: Pavel Březina <pbrezina@redhat.com> Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>

SBUS: Implement org.freedesktop.DBus.Properties.Get for primitive types This patch implements type-safe getters for primitive types and their arrays. The patch includes unit tests of all supported types and arrays of these types. All getter are synchronous. The getters never fail, instead, they return a default or 'not defined' value. Making the getters synchronous and always returning a value will make it significantly easier to implement the GetAll method.

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.
