The new capability VFIO_DIRTY_LOG_MANUAL_CLEAR and the new ioctl
VFIO_IOMMU_DIRTY_PAGES_FLAG_GET_BITMAP_NOCLEAR and
VFIO_IOMMU_DIRTY_PAGES_FLAG_CLEAR_BITMAP have been introduced in
the kernel, tweak the userspace side to use them.

Check if the kernel supports VFIO_DIRTY_LOG_MANUAL_CLEAR and
provide the log_clear() hook for vfio_memory_listener. If the
kernel supports it, deliever the clear message to kernel.
