nbd: support feature negotiation

nbd supports writing flags in bytes 24...27 of the header,
and uses that for the read-only flag. Add support for it
in qemu-nbd.

nbd: support NBD_SET_FLAGS ioctl

The nbd kernel module cannot enable DISCARD requests unless it is
informed about it. The flags field in the header is used for this,
and this patch adds support for it.

NBD: Use qemu_socket functions to open TCP and UNIX sockets

This commit has the side-effect of making the qemu-nbd binary
capable of binding to IPv6 addresses. ("-b ::1", for instance).
block/nbd.c fails to parse IPv6 IP addresses correctly at this
point, but will work over IPv6 when given a hostname. It still...

Improve qemu-nbd performance by 4400 %

This patch allows to reduce the boot time from an NBD server from 225 seconds to
5 seconds (time between the "boot cd:0" and the kernel init) for the

nbd: Introduce NBD named exports.

This patch allows to connect Qemu using NBD protocol to an nbd-server
using named exports.

For instance, if on the host "isoserver", in /etc/nbd-server/config, you have:

Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the
