7d3c6f1c43 Fix startup failure on Windows 8.1 due to unsupported IPV6_USER_MTU socket option being set
Newer mingw-w64 (starting from 8.0.1) introduces support for `IPV6_USER_MTU` socket
option [1], which is not supported on Windows 8.1 and older [2]. As there is no way
to avoid this socket option from being picked at compile time when targeting older
versions of Windows, check for `setsockopt(..., IPV6_USER_MTU, ...)` failures at
runtime in order to avoid startup failure on those versions of Windows where the
`IPV6_USER_MTU` socket option is unsupported.

[1]: mirror/mingw-w64@e30bff4
[2]: `WSAGetLastError()` returns `WSAENOPROTOOPT` (`Bad protocol option`) error code

88bf803297 Avoid treat normal hosts as unresponsive servers
This is a fix for issue #713

When infra-keep-probing is on, all hosts with expired entries were treated as
unresponsive servers and thus causing problems (see #713).

This commit change that, so that normal hosts with expired entries are treated
as unknown servers.

6a4ea692d4 Set IP_BIND_ADDRESS_NO_PORT on outbound tcp sockets
When bound to a local address the kernel does not know if the socket
will listen() or connect() and must reserve a port inmediately after
bind() effectively limiting the random port range to ~32k.
when IP_BIND_ADDRESS_NO_PORT is set, the kernel delays source port
allocation until the time the complete 4-tuple is known allowing
a much larger number of combinations
