Void functions returning NULL

[Tim Auckland]

FYI,

I just tried to compile cfengine 2.0.4 on HP-UX 11 with HP's C compiler.

The compile failed in cfservd.c where several functions have been
declared "void" but contain one of more "return NULL" instructions.
HP's C compiler doesn't let you get away with this (and I'm not
surprised!).

Commenting out the NULLs fixes the problem.

(It still complains a lot about incorrect types where "char" and
"unsigned char" have been freely mixed and also "void" and "void*", but
those at least don't prevent compilation).
