Convert the qemu-io command infrastructure to use QEMU's Error API
(Error **errp) for error propagation instead of printing directly to
stdout/stderr via printf/fprintf.
The cfunc_t typedef, all ~35 command functions, the dispatcher chain
(command/init_check_command/qemuio_command), and helper functions
(parse_pattern, create_iovec, qemu_io_alloc_from_file) all gain an
Error **errp parameter. Async completion callbacks (aio_read_done,
aio_write_done, aio_discard_done) use error_report() since they have
no Error path back to the caller.
Update tests:
- error_report_err() prepends qemu-io: prefix
- copy-before-write: check the HMP return value, rather than stdio
- other tests: update to check JSON {"return": "Error: error text"}
