* test/run.sh: Changed 'stpd' references to 'staprun'.

	* conversions.stp (hexstring, string): Removed functions.  Because
	of parser changes, "string" is now a reserved word and cannot be a
	function name.  Use 'sprintf("0x%x", num)' to replace hexstring()
	and either 'sprint(num)' or 'sprintf("%d", num)' to replace
	string().

	* syscalls.stp (syscall.accept, syscall.alarm, syscall.close,
	syscall.dup, syscall.epoll_create, syscall.exit, syscall.fchdir,
	syscall.fdatasync, syscall.fsync, syscall.getsid) Changed
	'string()' calls to 'sprint()' calls.
	* syscalls2.stp (syscall.sched_get_priority_max,
	syscall.sched_get_priority_min, syscall.sched_getscheduler,
	syscall.setfsgid, syscall.setfsgid16, syscall.setfsuid,
	syscall.setfsuid16, syscall.setgid, syscall.setgid16,
	syscall.setuid, syscall.setuid16, syscall.ssetmask,
	syscall.timer_delete, syscall.timer_getoverrun): Ditto.
	* i686/syscalls.stp (syscall.iopl, syscall.rt_sigreturn,
	syscall.sigreturn): Ditto.
	* ppc64/syscalls.stp (syscall.ppc64_personality): Ditto.
	* x86_64/syscalls.stp (kernel.syscall.iopl, kernel.syscall.umask):
	Ditto.

	* test/ctostp.sh: Uses 'sprint()' instead of 'string()' in
	generated systemtap code.

SCRIPTS:
   run.sh - This is the driver for automated testing.
            To run: ./run.sh stpdirectory c_binaries_directory
            Result: log/timestamp.log discerpancy report

   ctostp.sh - This script generates corresponding stp probe script
               files for every C file found in the input directory.
               To Run: ctostp.sh input output where input is the
               directory containing the C files to convert. Output
               is the directory to store the corresponding stp
               files.

   build.sh - This script expedites the process of compiling all
              of the c files. When the "compile" flag is given
              it creates a directory called bin, which stores the
              compiled C programs. ./build.sh clean removes the
              binaries, and ./build.sh run attempts to execute all
              of the programs in cfiles/bin.
