If the remote end of a connection oriented socket hangs up, generating
an EPIPE error is preferable over an unhandled SIGPIPE signal.

Consistent with what is done in udp.c, allow to explicitly disable listen
with listen=0.

This fixes warnings about making integers from pointers without
a cast, and avoids the theoretical case where the lower 32 bits of
the pointer would all be zero where the implicit cast wouldn't give
the right result.

This lowers the level of warnings printed if trying to connect
to a host name that provides both v6 and v4 addresses but the
service only is available on the v4 address (often occurring for
'localhost', with servers that aren't v6-aware).

This should be closer to how tcp behaved longer ago and should
fix the issue with idle connections timing out.

Fixes Ticket2694

Document the functions and have both use a millisecond timeout and
check for interrupt.

Introduce ff_listen_connect, to be shared with the other
non-tcp network protocols.

Introduce ff_listen_bind, to be shared with the other non-tcp
network protocols.

Without this patch a user a bit absent-minded may not notice that
the connection doesn't work because the port is missing.

This gives you the proper v4 or v6 version of the "any address",
allowing receiving connections on any address on the machine.

This heaader is required for close() for sockets in network
code. For winsock, the equivalent function is defined in the
winsock2.h header.

This avoids having the HAVE_UNISTD_H in all files dealing with
raw sockets.

Also use ff_neterrno() instead of errno directly (which doesn't work
on windows), for getting the error code.
