slirp: use libslirp migration code
slirp migration code uses QEMU vmstate so far, when building WITH_QEMU.
Introduce slirp_state_{load,save,version}() functions to move the
state saving handling to libslirp side.
So far, the bitstream compatibility should remain equal with current
QEMU, as this is effectively using the same code, with the same format
etc. When libslirp is made standalone, we will need some mechanism to
ensure bitstream compatibility regardless of the libslirp version
installed. See the FIXME note in the code.

net: netmap: improve netmap_receive_iov()
Changes:
- Save CPU cycles by computing the return value while scanning the
input iovec, rather than calling iov_size() at the end.
- Remove check for s->tx != NULL, because it cannot happen.
- Cache ring->tail in a local variable and use it to check for
space in the TX ring. The use of nm_ring_empty() was invalid,
because nobody is updating ring->cur and ring->head at that point.
- In case we run out of netmap slots in the middle of a packet,
move the wake-up point by advancing ring->cur, but do not
expose the incomplete packet (i.e., by updating also ring->head).

vhost-net-user: add stubs for when no virtio-net device is present
hw/net/vhost_net.c needs functions that are declared in net/vhost-user.c: the
vhost-user code is always compiled into QEMU, only the constructor
net_init_vhost_user is unreachable. Also, net/vhost-user.c needs functions
declared in hw/virtio/vhost-stub.c even if no virtio device exists.
Break this dependency. First, add a minimal version of net/vhost-user.c,
with no functionality and no dependency on vhost code. Second, #ifdef out
the calls back to net/vhost-user.c from hw/net/vhost_net.c.
While at it, this patch fixes the CONFIG_VHOST_NET_USE*D* typo.
