With "detach-all=on" for display, QEMU starts with all VC windows
detached automatically.
If used with "full-screen=on", it places individual windows (from
top window) starting from monitor 0 or monitor n in case monitor=n.
In case # mon < # VCs, only same number of VCs as # mon will be sent to
the monitors for full-screen while others are remaining in windowed-mode.
Target monitor number for individual VC is rotated in case monitor=n
(n != 0) (e.g. if monitor=1 and # VCs = 2, the top window will be
full-screened on monitor 1 and top second window will be full-screened
on monitor 0.)
v2: update Since version to 7.1
