Subsystem maintainers will need to review these patches. Hopefully many
of them are willing to do the conversion themselves. Code examples for
common conversions would help (e.g. QemuOpts to QAPI, strtol() to QAPI,
etc).

Do error messages need to be preserved? For example, maybe the input
validation order or the actual error message is different with QAPI and
that may affect programs that launch QEMU.

Is there any way to detect incompatible command-line changes besides
running make check? One idea is to run a fuzzer to check if certain
inputs are accepted by the new/old version but not the other.
