This patch series add AF_VSOCK channel support to QGA on Windows.

For that purpose, all common channel logic that can be reused was
extracted from channel-posix.c into channel-common.[ch].

Also, a header from kvm-guest-drivers-windows was vendored (and trimmed
and adjusted to pass checkpatch).

Most importantly, for vsock-listen to actually work on Windows, the
viosock driver from a very recent kvm-guest-drivers-windows build (not
released yet) is required: the 687c776 commit can be used as a support
marker.
