I think the basic requirement for any HMP replacement is that it just
works, i.e. no manual setting up of sockets etc. like for qmp-shell.

If it's an external process, QEMU should just launch it automatically,
and the user interface should still go through the usual chardevs so
that the current backends still work and the default of '-monitor vc'
can be retained.

(Of course, once this plumbing has been done, it could be reused for
qmp-shell to provide a nicer and more integrated option there, too.)

This pretty much means that it has to be in the same project, or at
least a subproject that is automatically downloaded when building QEMU.
