SBUS: Add support for <node /> in introspection Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

sbus: support org.freedesktop.DBus.Introspectable This commit brings back support of Introspectable interface and enables support of multiple interfaces there. It also refactors the old code so the generator and introspect xml format especially is more readable. Reviewed-by: Jakub Hrozek <jhrozek@redhat.com>

sbus: Add type-safe DBus method handlers and finish functions Type safe method handlers allow methods not to have to do tedious unwrapping and wrapping of DBus method call messages or replies. Arguments of the following DBus types are supported in type-safe method handlers. In addition arrays of these are supported. y: uint8_t b: bool (but no arrays, yet) n: int16_t q: uint16_t i: int32_t u: uint32_t x: int64_t t: uint64_t d: double s: char * (utf8 string) o: char * (object path) As an exception, arrays of booleans are not supported, but could be added later. Other more complex types could be added later if desired. If a method has other argument types, then it must be marked as having a raw handler (see below). Internally each method can have a type specific invoker function which unpacks the incoming arguments and invokes the method handler with the correct arguments. Each method also has a finish which accepts the type-safe out arguments (ie: return values) and builds the reply message. Like other request 'finish' functions, these free the request talloc context, and are to be used in place of sbus_request_finish() or friends. Raw method handlers parse their own method arguments, and prepare their own reply (ideally using sbus_request_finish() helpers). They can also do strange things like have variable arguments. To mark a DBus method as having a raw method handler use the following annotation: <annotation name="org.freedesktop.sssd.RawHandler" value="true"/> Raw methods do not have invokers or finish functions. I've left all of the internal peer to peer communication using raw method handlers. No code changes here.

SBUS: Create an sbus_method_meta instance for Introspection Also fixes a warning about uninitialized 'method' as the 'method' variable was unused and not set previously when introspecting.

SBUS: Generate introspection from the interface meta structure https://fedorahosted.org/sssd/ticket/2234 This patch generates the introspection data from the sbus interface meta structure. The generated XML conforms to http://dbus.freedesktop.org/doc/dbus-specification.html#introspection-format The XML description of the interface also always includes the org.freedesktop.DBus.Introspectable interface, which this patch also allows in the policy settings.
