Steve Sistare efc6587313 migration: cpr-exec save and load ...

To preserve CPR state across exec, create a QEMUFile based on a memfd, and
keep the memfd open across exec.  Save the value of the memfd in an
environment variable so post-exec QEMU can find it.

These new functions are called in a subsequent patch.
