[libvirt] [PATCH 07/13] blockjob: wire up RPC for block copy

[Eric Blake]

Almost trivial; the trick was dealing with the fact that we're
stuck with 'unsigned long bandwidth' due to earlier design
decisions.

* src/remote/remote_protocol.x (remote_domain_block_copy_args):
New struct.
* src/remote/remote_driver.c (remote_driver): Use it.
* src/rpc/gendispatch.pl (name_to_ProcName): Cater to legacy
bandwidth type.
* src/remote_protocol-structs: Regenerate.
