the socks server port in the test suite. This is the default setting
unless a tinkered built ssh is being used.

port forwarding, our socks port, prevents ssh from running on some systems.

By default, ssh binds local port forwardings to the loopback address, since this
was the address being given as the explicit bind address, now it isn't given.

is inited at the start of the DO action. I removed the Curl_transfer_keeper
struct completely, and I had to move out a few struct members (that had to

struct is accessed with SessionHandle->req.

One of the biggest reasons for doing this was the bunch of duplicate struct
members in HandleData and Curl_transfer_keeper since it was really messy to
keep track of two variables with the same name and basically the same purpose!

the same state struct as the host auth, so both could never be used at the
same time! I fixed it (without being able to check) to use two separate
structs to allow authentication using Negotiate on host and proxy
simultanouesly.
