     root should always be excluded from the test for /etc/nologin instead
     of having it always enforced even when marked as ignorenologin.  This
     regressed when the logic was incompletely flipped around in rev 1.251

[monitor.c monitor_wrap.c session.h servconf.c servconf.h session.c]
     [sshd_config sshd_config.5]
     Make the maximum number of sessions run-time controllable via
     a sshd_config MaxSessions knob. This is useful for disabling
     login/shell/subsystem access while leaving port-forwarding working
     (MaxSessions 0), disabling connection multiplexing (MaxSessions 1) or
     simply increasing the number of allows multiplexed sessions.
     Because some bozos are sure to configure MaxSessions in excess of the
     number of available file descriptors in sshd (which, at peak, might be
     as many as 9*MaxSessions), audit sshd to ensure that it doesn't leak fds
     on error paths, and make it fail gracefully on out-of-fd conditions -
     sending channel errors instead of than exiting with fatal().

     Implement a channel success/failure status confirmation callback

     Also includes a abandonment callback to clean up if a channel is
     closed without sending confirmation messages. This probably
     shouldn't happen in compliant implementations, but it could be

     this breaks older openssh clients (< 3.5) if they insist on
