Fix address handling in inet_nonblocking_connect
getaddrinfo can give us a list of addresses, but we only try toconnect to the first one. If that fails we never proceed tothe next one. This is common on desktop setups that often have ipv6configured but not actually working....
Separate inet_connect into inet_connect (blocking) and inet_nonblocking_connect
No need to add non blocking parameters to the blocking inet_connectadd block parameter for inet_connect_opts instead of using QemuOpt "block".

net: inet_connect(), inet_connect_opts(): add in_progress argument
It's used to indicate the special case where a valid file-descriptoris returned (ie. success) but the connection can't be completedw/o blocking.
This is needed because QERR_SOCKET_CONNECT_IN_PROGRESS is not...
sockets: change inet_connect() to support nonblock socket
Add a bool argument to inet_connect() to assign if set socketto block/nonblock, and delete original argument 'socktype'that is unused.Add a new argument to inet_connect()/inet_connect_opts(),to pass back connect error by error class....
sockets: use error class to pass listen error
Add a new argument in inet_listen()/inet_listen_opts()to pass back listen error.
Change nbd, qemu-char, vnc to use new interface.

w32: Move defines for socket specific errors to qemu-os-win32.h
As those defines are only used for w32,they should be in the header file for w32.
All files which include slirp.h or qemu_socket.h alsoinclude qemu-os-win32.h.

Don't leak file descriptors
We're leaking file descriptors to child processes. Set FD_CLOEXEC on filedescriptors that don't need to be passed to children to stop this misbehaviour.

While being at it: create a new inet_dgram_opts() function for udp setup,so udp can handle IPv6 now.
