[PATCH v2 24/31] qemu-io: Use user_creatable_process_cmdline() for --object

[Kevin Wolf]

This switches qemu-io from a QemuOpts-based parser for --object to
user_creatable_process_cmdline() which uses a keyval parser and enforces
the QAPI schema.

Apart from being a cleanup, this makes non-scalar properties accessible.
