Provide an introduction to the main components of a CXL system,
with detailed explanation of memory interleaving, example command
lines and kernel configuration.
This was a challenging document to write due to the need to extract
only that subset of CXL information which is relevant to either
users of QEMU emulation of CXL or to those interested in the
implementation. Much of CXL is concerned with specific elements of
the protocol, management of memory pooling etc which is simply
not relevant to what is currently planned for CXL emulation
in QEMU. All comments welcome

Change namespaces to be shared namespaces by default (parameter
shared=on). Keep shared=off for older machine types.

We already have a section on USB in the rST manual; fold
the information in docs/usb-storage.txt into it.
We add 'format=raw' to the various -drive options in the code
examples, because QEMU will print warnings these days if you
omit it.

While we do mention some of this stuff in the various daemons and
manuals the subtleties of the socket and memory sharing are sometimes
missed. This document attempts to give some background on vhost-user
daemons in general terms.
