Subject: Eliminate warnings about missing prototypes

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.
