If PAM is configured to read user-specified environment variables
and UseLogin=yes in sshd_config, then a hostile local user may
attack /bin/login via LD_PRELOAD or similar environment variables
set via PAM.
CVE-2015-8325, found by Shayan Sadigh, via Colin Watson
Replace by defining IPPORT_RESERVED to zero on Cygwin, which should have
the same effect without causing problems syncing patches with OpenBSD.
Resync the two affected functions with OpenBSD. ok djm, sanity checked
by Corinna.
We accidentally send an empty string and a zero uint32 with
every direct-streamlocal@openssh.com channel open, in contravention of our
own spec.
Fixing this is too hard wrt existing versions that expect these
fields to be present and fatal() if they aren't, so document them
as "reserved" fields in the PROTOCOL spec as though we always
intended this and let us never speak of it again.

Another use for fcntl() and thus of the superfluous 3rd
parameter is when sanitising standard fd's before calling daemon().
Use a tweaked version of the ssh(1) function in all three places
found using fcntl() this way.

Filter debug messages out of log before picking the last

the connection.

Look back 3 lines for possible error messages. Changes
to the code mean that "Bad packet length" errors are 3 lines back instead of
the previous two, which meant we didn't skip some offsets that we intended
to.
