[PATCH v2 28/31] hmp: QAPIfy object_add

2021-02-24 Thread Kevin Wolf
This switches the HMP command object_add from a QemuOpts-based parser to
user_creatable_add_from_str() which uses a keyval parser and enforces
the QAPI schema.

Apart from being a cleanup, this makes non-scalar properties and help
accessible. In order for help to be printed to the monitor instead of
stdout, the printf() calls in the help functions are changed to
qemu_printf().
