 Hi Gerd,

     Merge branch 'scratch/tty-child-frames'

     Add support for child frames on tty

 This breaks xt-mouse-tests:

     (error "tty frame should be used")
    FAILED  1/3  xt-mouse-tracking-basic (0.776520 sec) at lisp/xt-mouse-tests.el:61

 Best regards, Michael.
 
 Hi Michael,
 
 The new code now _requires_ a tty frame to be used (decode_tty_frame,
 check_tty), which I think the tests can't provide, running in batch. And
 I'd rather not be less picky for the sake of these tests.

Why is that a problem?  A batch session does have a frame, you just
need to account for that.  I think the test that emits the error is
too strict, and should be relaxed when noninteractive is non-zero.  Or
maybe invert the test and check for !FRAME_WINDOW_P (which would then
allow the frame that exists in the batch session).
