[PATCH 0/2] nbd: build qemu-nbd on Windows

["Daniel P. Berrangé" <berrange@redhat.com>]

We are already building the NBD client and server on Windows when it is
used via the main system emulator binaries. This demonstrates there is
no fundamental blocker to buildig the qemu-nbd binary too.


In testing this I used:

   wine qemu-nbd.exe -t -p 9000 demo.img 

and

   wine qemu-img.exe info nbd:localhost:9000

In fact I tested the full matrix of native vs windows client and native
vs windows server.

I did notice that native qemu-img will sometimes hang when talking to
the windows qemu-nbd.exe binary, and the windows qemu-img will almost
always hang.

The hang happens in the "blk_unref" call in collect_image_info_list().
This suggests something related to the socket teardown / cleanup in
the NBD code.

While we should obviously investigate and fix that, I didn't consider
it a blocker for enabling build of qemu-nbd.exe, since we're already
building the same (buggy) NBD code in the system emulators on Windows.
