[authfd.c ssh-add.c authfd.h]
     Do not fall back to adding keys without contraints (ssh-add -c / -t ...)
     when the agent refuses the constrained add request. This was a useful
     migration measure back in 2002 when constraints were new, but just
     adds risk now.
     bz #1612, report and patch from dkg AT fifthhorseman.net; ok markus@
