Use LOGNAME to get current user and fall back to whoami if
not set. Mainly to benefit -portable since some platforms don't have whoami.

Turkish locales are unique in their handling of the letters 'i' and
'I' (yes, they are different letters) and OpenSSH isn't remotely
prepared to deal with that. For now, the best we can do is to force
OpenSSH to use the C/POSIX locale and try to preserve the UTF-8
encoding if possible.

make IdentityFile successfully load and use certificates that
have no corresponding bare public key. E.g. just a private id_rsa and
certificate id_rsa-cert.pub (and no id_rsa.pub).

Fix public key authentication when multiple
authentication is in use. Instead of deleting and re-preparing the entire
keys list, just reset the 'used' flags; the keys list is already in a good
order (with already- tried keys at the back)

Unlink PidFile on SIGHUP and always recreate it when the
new sshd starts. Regression tests (and possibly other things) depend on the
pidfile being recreated after SIGHUP, and unlinking it means it won't contain
a stale pid if sshd fails to restart. ok djm@ markus@

add a whitelist of paths from which ssh-agent will load

Add a sshd_config DisableForwaring option that disables
X11, agent, TCP, tunnel and Unix domain socket forwarding, as well as
anything else we might implement in the future.
This, like the 'restrict' authorized_keys flag, is intended to be a
simple and future-proof way of restricting an account. Suggested as
a complement to 'restrict' by Jann Horn; ok markus@

When a forced-command appears in both a certificate and
an authorized keys/principals command= restriction, refuse to accept the
certificate unless they are identical.
The previous (documented) behaviour of having the certificate forced-
command override the other could be a bit confused and more error-prone.

On startup, check to see if sshd is already daemonized
and if so, skip the call to daemon() and do not rewrite the PidFile. This
means that when sshd re-execs itself on SIGHUP the process ID will no longer
change. Should address bz#2641. ok djm@ markus@.

Reverse args to sshd-log-wrapper. Matches change in

use sshbuf_allocate() to pre-allocate the buffer used for
loading keys. This avoids implicit realloc inside the buffer code, which
might theoretically leave fragments of the key on the heap. This doesn't
appear to happen in practice for normal sized keys, but was observed for
novelty oversize ones.
