Applies on top of Peter's removal of commandline parsing
https://www.redhat.com/archives/libvir-list/2019-June/msg00405.html
After removal of qemuProcessAttach there is no codepath that could
possibly set monJSON to false (not that libvirt would be able to much
with such domain), so we can finish cleaning it up.
Ján Tomko (10):
qemu: also delete qemuProcessAttach
qemu: assume monJSON is always true
qemu: domain: remove monJSON field
qemu: stop formatting json='1' in status XML
qemu: remove json argument from qemuMonitorOpen
qemu: monitor: assume JSON in QEMU_CHECK_MONITOR macro
qemu: monitor: remove mon->json checks
qemu: monitor: remove the json field
qemu: monitor: use VIR_AUTOFREE in qemuMonitor*VideoSize
qemu: monitor: s/ret/rc/ in UpdateVideoSize functions

New subject: [libvirt] [PATCH 01/10] qemu: also delete qemuProcessAttach
Now that the virDomainQemuAttach API returns an error, we can remove the
unused qemuProcessAttach function as well, deleting the only user
that possibly could have requested to open a non-JSON monitor.
