Similarly, use InetPton rather than WSAStringToAddress.
The WSAAddressToString function is intended to provide a user-readable
string and thus includes the port number. This breaks some use cases
on Windows which expect to get just the IP address.
Note: The InetPton and InetNtop functions are available only in Vista or above.
Also add checking for "would block" errors in send() and receive().
Check for set nonblocking failures in TCPConnector as well (generate warnings rather than errors)
This is a breaking change to dependencies that use the static ntcore
library. Unless the wpiutil library is also linked, linker errors will
result. This does not affect the shared ntcore library.
