John Levon 1f3b34e403 docs/interop/vfio-user: update protocol specification 
Refresh the protocol specification to the latest version implemented by
libvfio-user. All changes are backward compatible.

Note that QEMU client itself does not yet implement these extensions,
but as this is now the canonical specification, it needs to be kept up
to date.

Thanos Makatos da198e8f0f vfio-user: introduce vfio-user protocol specification 
This patch introduces the vfio-user protocol specification (formerly
known as VFIO-over-socket), which is designed to allow devices to be
emulated outside QEMU, in a separate process. vfio-user reuses the
existing VFIO defines, structs and concepts.

It has been earlier discussed as an RFC in:
"RFC: use VFIO over a UNIX domain socket to implement device offloading"
