qemu-nbd: move client handling to nbd.c

This patch sets up the fd handler in nbd.c instead of qemu-nbd.c. It
introduces NBDClient, which wraps the arguments to nbd_trip in a single
structure, so that we can add a notifier to it. This way, qemu-nbd can
know about disconnections....

nbd: support feature negotiation

nbd supports writing flags in bytes 24...27 of the header,

Fix include statements for qemu-common.h

  • qemu-common.h is not a system include file, so it should be included
    with "" instead of <>. Otherwise incremental builds might fail
    because only local include files are checked for changes.
  • linux-user/syscall.c included the file twice....

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...

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:
