ui/console: eliminate QOM properties from qemu_console_is_multihead()
According to Marc-André's and Gerd's descriptions, the "device" and
"head" members of QemuGraphicConsole are exposed as QOM properties for two
purposes:
(1) Introspection (e.g., "qom-get" monitor command).
(2) A VNC server can display a specific device + head. This lets us run a
multihead configuration by using multiple VNC servers (one for each
head).
Further, we can link input devices to device + head, so input events
are routed to different devices dependent on where they are coming
from. Which is most useful for tablet devices in a VNC multihead
setup, each head has its own tablet device then. This does requires
manual guest-side configuration, for establishing the same tablet <->
head relationship.
However, neither goal seems to justify the complicated QOM property lookup
that's internal to qemu_console_is_multihead().
Rework qemu_console_is_multihead() with plain old C language field
accesses.
