fallthrough to a separate case/default label break; isn't very readable.

Convert pseudo-keyword fallthrough; statements to a simple break; when
the next label is case or default and the only statement in the next
label block is break;

Found using:

$ grep-2.5.4 -rP --include=*.[ch] -n "fallthrough;(\s*(case\s+\w+|default)\s*:\s*){1,7}break;" *

Miscellanea:

o Move or coalesce a couple label blocks above a default: block.
