Summary: Proxy connection close during auth not handled by multi

Initial Comment:
When doing a CONNECT request through a ISA Server 2006
proxy that requires authentication, the ISA proxy returns Connection:Close on the initial connection along with the authentication header.

curl_easy path handles this correctly by opening a new connection to the proxy and redoing the handshake with the chosen auth protocol.

curl_multi is missing this logic in the state machine.

The patch below adds that logic to the state machine.

Here's the patch since I can't seem to attach the file due to some silly
sourceforge error:
