Once qmp_chardev_add() can handle everything supported by
qemu_chr_new_from_opts we can flip over, make qmp_chardev_add the
primary interface and qemu_chr_new_from_opts legacy (which then does the
opts->ChardevBackend conversion and calls qmp_chardev_add).
We are not there yet, even with the full series applied.
And even when we arrive there some day we don't have to touch
hmp_chardev_add when making the switch ;)
cheers,
Gerd
