Commit: Po Lu <luangruo@yahoo.com>

    Fix creating frames with an initial value of `fullscreen' on Haiku
    
    * src/haikufns.c (haiku_create_frame): Set configury_done and do
    pending fullscreen change if any.
    * src/haikuterm.c (haiku_fullscreen): Defer actually setting
    fullscreen until configury_done is set.
    * src/haikuterm.h (struct haiku_output): New field
    `configury_done'.
