Steve Sistare 91792807d1 machine: aux-ram-share option 
Allocate auxilliary guest RAM as an anonymous file that is shareable
with an external process.  This option applies to memory allocated as
a side effect of creating various devices. It does not apply to
memory-backend-objects, whether explicitly specified on the command
line, or implicitly created by the -m command line option.

This option is intended to support new migration modes, in which the
memory region can be transferred in place to a new QEMU process, by sending
the memfd file descriptor to the process.  Memory contents are preserved,
and if the mode also transfers device descriptors, then pages that are
locked in memory for DMA remain locked.  This behavior is a pre-requisite
for supporting vfio, vdpa, and iommufd devices with the new modes.
