Plus a bunch of followup warnings.

Seems to be caused by ad7d28519de7cdc604efefac5c22fe9f88040586 which
adds an extra #include "qemu_socket.h" to qemu-common.h.

The following seems like the simplest fix. It successfully builds x86_32
and x86_64 stubdom.

A much more thorough sweep of what minios exposes to applications would
be nice but I think that is likely to be a big task, especially for this
point in the release.

8<------------------

minios: do not export {test,set,clear}_bit etc to applications
