ANSIfication of the hp2ps code. The most important changes are the correct use of the stdarg mechanism (former hacks could bite on other systems, so please tell upstream), inclusion of stdlib.h instead of declaring free yourself, adding a few missed PROTO()s and using size_t for xmalloc and xrealloc.: git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2399
