Now that C++17 introduced a special fallthrough keyword for
explicitly tagging switch cases that are supposed to fall
through, newer gcc versions also implement a feature request
from 2002 to warn about maybe unwanted fall-throughs in switch
cases in other languages (like C).
For C code, we can either add a gcc specific attribute at the
end of the switch case, or use a special comment that gcc checks
for, indicating that the fall-through behaviour is indeed
intended.
This patch adds a "/* fall-through */" comment at the end of
various case blocks to silence gcc warnings and in some cases
a break, where fall-through was probably not intended.

This patch eliminates warnings generated by the -Wmissing-prototypes
option. With this flag set, we are now forced to have prototypes for
all global, exported functions, that have to be made visible to the
definitions and we are forced to mark all local functions as static.
