nbd: Introduce NBD named exports.
This patch allows to connect Qemu using NBD protocol to an nbd-serverusing named exports.
For instance, if on the host "isoserver", in /etc/nbd-server/config, you have:

qemu-nbd: Improve error reporting
- use err(3) instead of errx(3) if errno is available to report why failed- let fail prior to daemon(3) if opening a nbd file is likely to fail after daemonizing to avoid silent failure exit- add missing 'ret = 1' when unix_socket_outgoing failed...
Replace calls of old bdrv_open

win32: pair qemu_memalign() with qemu_vfree()
Win32 suffers from a very big memory leak when dealing with SCSI devices.Each read/write request allocates memory with qemu_memalign (ieVirtualAlloc) but frees it with qemu_free (ie free).Pair all qemu_memalign() calls with qemu_vfree() to prevent such leaks....
Clean-up a little bit the RW related bits of BDRV_O_FLAGS. BDRV_O_RDONLY gone (and so is BDRV_O_ACCESS). Default value for bdrv_flags (0/zero) is READ-ONLY. Need to explicitly request READ-WRITE.
Instead of using the field 'readonly' of the BlockDriverState struct for passing the request,...
