620aaf234e vfio_user: DmaUnmap expects a reply with payload
The current code was expecting a reply with only the header, which
wasn't reading the rest of payload that was provided. This was causing
the following replies to be completely wrong as they were shifted by the
previous payload that wasn't read.

The simple way to fix this issue is by reading the header and the
expected payload when getting a reply from a DmaUnmap request.

d13eea3ba1 vfio_user: Fix debug output to include reply for DeviceGetRegionInfo
The reply was being printed before it had been read so it was just
showing the default values.

2e236c53c8 vfio_user: Implement client side support
Implement (most) of the client side (i.e. VMM side) of the vfio-user
protocol:

https://github.com/nutanix/libvfio-user/blob/master/docs/vfio-user.rst

Items that are not implemented (because they are optimisations or unused
due to alternative solutions:

* VFIO_USER_DMA_READ/WRITE - this is a way for the server to read guest
  memory if the guest memory is not shared by fd where the client
  doesn't support it. However since we do support sharing the memory by
  fd this is not required.
* VFIO_USER_GET_REGION_IO_FDS - an optimisation to bypass the VMM by
  having KVM talk directly to the backend using ioregionfd
* VFIO_USER_DIRTY_PAGES - for the implementation of live migration
