    spice: send updates only for changed screen content
    
    when creating screen updates go compare the current guest screen
    against the mirror (which holds the most recent update sent), then
    only create updates for the screen areas which did actually change.
    
    [ v2: drop redundant qemu_spice_create_one_update call ]

    spice: split qemu_spice_create_update
    
    Creating one function which creates a single update for a given
    rectangle.  And one (for now) pretty simple wrapper around it to
    queue up screen updates for the dirty region.
    
    [ v2: also update bounding box ]

    qxl: Add set_client_capabilities() interface to QXLInterface
    
    This new interface lets spice server inform the guest whether
    
    (a) a client is connected
    (b) what capabilities the client has
    
    There is a fixed number (464) of bits reserved for capabilities, and
    when the capabilities bits change, the QXL_INTERRUPT_CLIENT interrupt
    is generated.

    qxl: add QXL_IO_MONITORS_CONFIG_ASYNC
    
    Revision bumped to 4 for new IO support, enabled for spice-server >=
    0.11.1. New io enabled if revision is 4. Revision can be set to 4.
    
    [ kraxel: 3 continues to be the default revision.  Once we have a new
              stable spice-server release and the qemu patches to enable
              the new bits merged we'll go flip the switch and make rev4
              the default ]
    
    This io calls the corresponding new spice api
    spice_qxl_monitors_config_async to let spice-server read a new guest set
    monitors config and notify the client.
    
    On migration reissue spice_qxl_monitors_config_async.

    spice: adding seamless-migration option to the command line
    
    The seamless-migration flag is required in order to identify
    whether libvirt supports the new QEVENT_SPICE_MIGRATE_COMPLETED or not
    (by default the flag is off).
    New libvirt versions that wait for QEVENT_SPICE_MIGRATE_COMPLETED should turn on this flag.
    When this flag is off, spice fallbacks to its old migration method, which
    can result in data loss.

    spice: add 'migrated' flag to spice info
    
    The flag is 'true' when spice migration has completed on the src side.
    It is needed for a case where libvirt dies before migration completes
    and it misses the event QEVENT_SPICE_MIGRATE_COMPLETED.
    When libvirt is restored and queries the migration status, it also needs
    to query spice and check if its migration has completed.

    spice migration: add QEVENT_SPICE_MIGRATE_COMPLETED
    
    When migrating, libvirt queries the migration status, and upon migration
    completions, it closes the migration src. On the other hand, when
    migration is completed, spice transfers data from the src to destination
    via the client. This data is required for keeping the spice session
    after migration, without suffering from data loss and inconsistencies.
    In order to allow this data transfer, we add QEVENT for signaling
    libvirt that spice migration has completed, and libvirt needs to wait
    for this event before quitting the src process.

    spice: notify spice server on vm start/stop
    
    Spice server needs to know about the vm state in order to prevent
    attempts to write to devices when they are stopped, mainly during
    the non-live stage of migration.
    Instead, spice will take care of restoring this writes, on the migration
    target side, after migration completes.

    spice: abort on invalid streaming cmdline params
    
    When parsing its command line parameters, spice aborts when it
    finds unexpected values, except for the 'streaming-video' option.
    This happens because the parsing of the parameters for this option
    is done using the 'name2enum' helper, which does not error out
    on unknown values. Using the 'parse_name' helper makes sure we
    error out in this case. Looking at git history, the use of
    'name2enum' instead of 'parse_name' seems to have been an oversight,
    so let's change to that now.
