net: increase buffer size to accommodate Jumbo frame pkts

Socket buffer sizes were hard-coded to 4K for VDE and socket netdevs. Bump this
up to 68K (ala tap netdev) to handle maximum GSO packet size (64k) plus plenty
of room for the ethernet and virtio_net headers....

net: use socket_set_nodelay() for -netdev socket

Reduce -netdev socket latency by disabling the Nagle algorithm on
SOCK_STREAM sockets in net/socket.c. Since we are tunelling Ethernet
over TCP we shouldn't artificially delay outgoing packets, let the guest...

MinGW: Replace setsockopt by qemu_setsocketopt

Instead of adding missing type casts which are needed by MinGW for the
4th argument, the patch uses qemu_setsockopt which was invented for this
purpose.

tap: forbid creating multiqueue tap when hub is used

Obviously, hub does not support multiqueue tap. So this patch forbids creating
multiple queue tap when hub is used to prevent the crash when command line such
as "-net tap,queues=2" is used.

tap: set IFF_ONE_QUEUE per default

historically the kernel queues packets two times. once
at the device and second in qdisc. this is believed to cause
interface stalls if one of these queues overruns.

setting IFF_ONE_QUEUE is the default in kernels >= 3.8. the...

net: reduce the unnecessary memory allocation of multiqueue

Edivaldo reports a problem that the array of NetClientState in NICState is too
large - MAX_QUEUE_NUM(1024) which will wastes memory even if multiqueue is not
used.

Instead of static arrays, solving this issue by allocating the queues on demand...
