Er, infrun single-steps through trampolines rather than skipping over them.


Oh right.  This would leave us sitting in the trampoline instead of
automatically skipping them; makes sense.

(note the choice of word - trampoline - there are many types of trampoline and for each GDB either steps through it or returns from it)


Another [SIGTRAMP_FRAME] attribute is how to display it when doing a backtrace or stop.
