list: Implement RPC calls for virStoragePoolListAllVolumes

The RPC generator doesn't returning support list of object, this
patch do the work manually.

  * daemon/remote.c:
    Implemente the server side handler remoteDispatchStoragePoolListAllVolumes

  * src/remote/remote_driver.c:
    Add remote driver handler remoteStoragePoolListAllVolumes

  * src/remote/remote_protocol.x:
    New RPC procedure REMOTE_PROC_STORAGE_POOL_LIST_ALL_VOLUMES and
    structs to represent the args and ret for it.

  * src/remote_protocol-structs: Likewise.
