Introduce an INIT state for the SSH state machine and set libssh2
non-blocking in that so that it is set properly before
libssh2_session_startup() is called.

libssh2 1.2.6 and later handle >32bit file sizes properly even on 32bit
architectures and we make sure to use that ability.

Howard Chu brought the bulk work of this patch that properly
moves out the sending and recving of data to the parts of the
code that are properly responsible for the various ways of doing
so.
Daniel Stenberg assisted with polishing a few bits and fixed some
minor flaws in the original patch.
Another upside of this patch is that we now abuse CURLcodes less
with the "magic" -1 return codes and instead use CURLE_AGAIN more
consistently.
crashed libcurl. This is now addressed by making sure we use "plain send"
internally when doing the socks handshake instead of the Curl_write()
function which is designed to use the "target" protocol. That's then SCP or
SFTP in this case. I also took the opportunity and cleaned up some ssh-
related #ifdefs in the code for readability.
doing an FTP transfer is removed from a multi handle before completion. The
fix also fixed the "alive counter" to be correct on "premature removal" for
all protocols.
