Remote protocol support for storage vol upload/download APIs

* daemon/remote.c, src/remote/remote_driver.c: Implementation
  of storage vol upload/download APIs
* src/remote/remote_protocol.x: Wire protocol definition for
  upload/download
* daemon/remote_dispatch_args.h, daemon/remote_dispatch_prototypes.h,
  daemon/remote_dispatch_table.h, src/remote/remote_protocol.h,
  src/remote/remote_protocol.c: Re-generate
