Yishai Hadas 0c9a38fee8 vfio/mlx5: Introduce SW headers for migration states
As mentioned in the previous patches, mlx5 is transferring multiple
states when the PRE_COPY protocol is used. This states mechanism
requires the target VM to know the states' size in order to execute
multiple loads.  Therefore, add SW header, with the needed information,
for each saved state the source VM is transferring to the target VM.

This patch implements the source VM handling of the headers, following
patch will implement the target VM handling of the headers.
