linkprop.m: Overhaul function for performance and Matlab compatibility. * NEWS: Announce changes in linkprop behavior. * linkprop.m: Redo docstring. Add more input validation. When linking, set property values to be that of the first object in the list (missing Matlab compatibility). Use onCleanup instead of an hggroup in order for 'clear hlink' command to correctly unlink properties. For performance, avoid for loops in update_prop and use set() with multiple handles. Add %!demo, %!test, and %!error code to verify function.

27 ** linkprop has been completely re-coded for performance and Matlab
28 compatibility. It now returns a linkprop object which must be stored
29 in a variable for as long as the graphic objects should remain linked.
30 To unlink properties use 'clear hlink' where hlink is the variable
31 containing the linkprop object.
