0a843d9a0e upstream: move client/server SSH-* banners to buffers under
ssh->kex and factor out the banner exchange. This eliminates some common code
from the client and server.

Also be more strict about handling \r characters - these should only
be accepted immediately before \n (pointed out by Jann Horn).

Inspired by a patch from Markus Schmidt.

72ef7c148c support --without-openssl at configure time
Disables and removes dependency on OpenSSL. Many features don't
work and the set of crypto options is greatly restricted. This
will only work on system with native arc4random or /dev/urandom.

Considered highly experimental for now.

     makes the pain stop in one easy step
     NB. portable commit contains everything *except* removing includes.h, as
     that will take a fair bit more work as we move headers that are required
     for portability workarounds to defines.h. (also, this step wasn't "easy")
