kgdb fixes for 4.20-rc3

Browse source

The most important changes here are two fixes for kdb regressions causes by
 the hashing of %p pointers together with a fix for a potential overflow in
 kdb tab completion handling (and warning fix).
 
 Also included are a set of changes in preparation to (eventually) enable
 -Wimplicit-fallthrough.
