Apply the same get_remote_name_or_ip -> session_get_remote_name_or_ip
change as commit 95767262 to the code inside #ifdef LOGIN_NEEDS_UTMPX.
Fixes build on AIX.
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.

Replace <sys/param.h> with <limits.h> and other less
dirty headers where possible. Annotate <sys/param.h> lines with their
current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1,
LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of
MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.

make internal handling of filename arguments of "none"
more consistent with ssh. "none" arguments are now replaced with NULL when
the configuration is finalised.
Simplifies checking later on (just need to test not-NULL rather than
that + strcmp) and cleans up some inconsistencies. ok markus@

Add support for Unix domain socket forwarding. A remote TCP port
may be forwarded to a local Unix domain socket and vice versa or
both ends may be a Unix domain socket. This is a reimplementation
