Remove various warnings, fix pppol2tp install

This fixes a collection of minor things that were resulting in
harmless warnings (accidental trigraphs, missing prototypes,
signed/unsigned char being used interchangeably) and corrects
an error in the pppol2tp makefile, which meant that it wasn't
installing anything.
