1. Updated makefile
	a. scripted the compilation and linking of every .c in TESTDIR
	   (this bit was hardcoded for pollthr test earlier)
	b. make clean now also cleans test objects and executables
2. Trimmed cc_of_util API arguments (removed the max socket/pipe as
  that is always the ones #defined in cc_of_global.)

Compiled. Also, existing ut pass.
