[Libguestfs] [PATCH v2 2/9] qapi: Mark unstable QMP parts with feature 'unstable'

Add special feature 'unstable' everywhere the name starts with 'x-', except for InputBarrierProperties member x-origin and MemoryBackendProperties member x-use-canonical-path-for-ramblock-id, because these two are actually stable.
