2018-10-29block/dirty-bitmaps: add user_locked status checkerJohn Snow
Instead of both frozen and qmp_locked checks, wrap it into one check. frozen implies the bitmap is split in two (for backup), and shouldn't be modified. qmp_locked implies it's being used by another operation, like being exported over NBD. In both cases it means we shouldn't allow the user to modify it in any meaningful way. Replace any usages where we check both frozen and qmp_locked with the new check.

2018-10-29spice: prepare for upcoming spice-server changeGerd Hoffmann
Future spice-server versions will call the client_monitors_config callback with the monitors list filtered to only include the monitors of the given display channel (aka QXLInstance). Luckily this is easily detectable at runtime, so we can prepare for that in advance and also make qemu compatible with both old and new spice-server versions. While being at it also use the console index instead of head number as array index. The later doesn't work correctly in case multiple display devices are present.
