	* main.cxx (printscript): New function containing code moved from
	main().
	(main): Added code to create cache directory, call function to
	generate hash, and see if we can use cached source/module.  If
	pass 4 is actually run to produce a new module, we call
	add_to_cache() to cache the result.
	* session.h (struct systemtap_session): Added hash/cache session
	data.
	* cache.cxx: New file handling adding/getting files from the
	cache.
	* cache.h: New header file for cache.cxx.
	* hash.cxx: New file containing C++ wrapper for routines in
	mdfour.c and the find_hash function which computes the hash file
	name for an input script.
	* hash.h: New header file for hash.cxx.
	* mdfour.c: New file containing MD4 hash code.
	* mdfour.h: New header file for mdfour.c.
	* util.cxx: New file containing several utility functions used by
	the caching code.
	* util.h: New header file for util.cxx.
	* Makefile.am: Added new C/C++ files.
	* Makefile.in: Regenerated.
