Bug #44874 [PATCH] dead pfsockopen'ed sockets aren't reaped when the remote end restarts

Description:
------------
A web page makes a connection to some service with pfsockopen, then that service dies and is restarted;  Future calls to pfsockopen can return the previously opened socket, to which I/O operations immediately fail.

This looks like a reincarnation of #23837, a bug which was closed in 2003.

I did manage to track down the error, to main/streams/xp_socket.c, line  280.  Change "0 == recv" to "0 >= recv".  Windows returns an error at this point, not 0, because it wants to return ECONNRESET.  When I make this change, the issue is resolved.

The latest version still exhibits the bad behavior.

Okay, here's a patch.
