revert smartmatch to 5.27.6 behaviour

The pumpking has determined that the CPAN breakage caused by changing
smartmatch [perl #132594] is too great for the smartmatch changes to
stay in for 5.28.

This reverts most of the merge in commit
da4e040f42421764ef069371d77c008e6b801f45.  All core behaviour and
documentation is reverted.  The removal of use of smartmatch from a couple
of tests (that aren't testing smartmatch) remains.  Customisation of
a couple of CPAN modules to make them portable across smartmatch types
remains.  A small bugfix in scope.c also remains.
