This patch adds an API to clear bits corresponding to guest free pages

Start the free page optimization after the migration bitmap is
synchronized. This can't be used in the stop© phase since the guest
is paused. Make sure the guest reporting has stopped before
synchronizing the migration dirty bitmap. Currently, the optimization is
added to precopy only.

The new feature enables the virtio-balloon device to receive hints of
guest free pages from the free page vq.
balloon_free_page_start - start guest free page hint reporting.
balloon_free_page_stop - stop guest free page hint reporting.
Note: balloon will report pages which were free at the time

The bitmap mutex is used to synchronize threads to update the dirty
bitmap and the migration_dirty_pages counter. This patch makes
migration_bitmap_clear_dirty update the bitmap and counter under the
