net: use "socket" model name for UDP sockets

Fix the problem that can not delete the udp socket.
It's caused by passing "udp" model to net_socket_udp_init,
but we do not have "udp" model in our model list.
Pass the right model "socket" to init function.

net: consolidate NetClientState header files into one

This patch doesn't seem much useful alone, I must admit. However,
it makes sense as part of the upcoming directory reorganization,
where I want to have include/net/tap.h as the net<->hw interface
for tap. Then having both net/tap.h and include/net/tap.h does...

net/socket: Fix compiler warning (regression for MinGW)

Commit 213fd5087e2e4e2da10ad266df0ba950cf7618bf removed a type cast
which is needed for MinGW:

net/socket.c:136: warning:
pointer targets in passing argument 2 of ‘sendto’ differ in signedness

net: broadcast hub packets if at least one port can receive

In commit 60c07d933c66c4b30a83b7ccbc8a0cb3df1b2d0e ("net: fix
qemu_can_send_packet logic") the "VLAN" broadcast behavior was changed
to queue packets if any net client cannot receive. It turns out that...

net: asynchronous send/receive infrastructure for net/socket.c

The net/socket.c net client is not truly asynchronous. This patch
borrows the qemu_set_fd_handler2() code from net/tap.c as the basis for
proper asynchronous send/receive.

Only read packets from the socket when the peer is able to receive....

net: EAGAIN handling for net/socket.c UDP

Implement asynchronous send for UDP (or other SOCK_DGRAM) sockets. If
send fails with EAGAIN we wait for the socket to become writable again.

net: EAGAIN handling for net/socket.c TCP

Replace spinning send_all() with a proper non-blocking send. When the
socket write buffer limit is reached, we should stop trying to send and
wait for the socket to become writable again.

Non-blocking TCP sockets can return in two different ways when the write...

net: do not report queued packets as sent

Net send functions have a return value where 0 means the packet has not
been sent and will be queued. A non-zero value means the packet was
sent or an error caused the packet to be dropped.

This patch fixes two instances where packets are queued but we return...
