x/sys/windows: support wsarecv error

[warent]

Proposal Details

Windows has an OpError "wsarecv: An existing connection was forcibly closed by the remote host." Easily reproducible by connecting to a TCP server and force closing the client.

zerrors_windows.go is quite comprehensive but does not include this error.

Side note, I believe there is one for wsasend as well which may be considered for inclusion.

These days we would normally add an error like this to the golang.org/x/sys/windows package, which does not require a proposal. Is there a reason that this needs to be in the syscall package?

That error is already there: windows.WSAECONNRESET.

@warent we need this info to proceed with this issue. Thanks.
