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
/usr/lib/gcc/amd64-mingw32msvc/4.4.4/../../../../amd64-mingw32msvc/include/winsock2.h:1313: note:...

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...

net: notify iothread after flushing queue

virtio-net has code to flush the queue and notify the iothread
whenever new receive buffers are added by the guest. That is
fine, and indeed we need to do the same in all other drivers.
However, notifying the iothread should be work for the network...

monitor: Rename+move net_handle_fd_param -> monitor_handle_fd_param

This patch renames+moves the net_handle_fd_param() caller used to
obtain a file descriptor from either qemu_parse_fd() (the normal case)
or from monitor_get_fd() (migration case) into a generically prefixed...

qapi: avoid reserved keywords

Clang compiler complained about use of reserved word 'restrict' in SLIRP
and QAPI.

Prefix C keywords with "q_", adjust SLIRP accordingly.

net: add the support for -netdev socket, listen

The -net socket,listen option does not work with the newer -netdev
syntax:

This patch makes it work now.

For the case where one vlan has multiple listenning sockets,...
