[PATCH 2/4] pi-condvars: add tst-condpi1.c, basic API test

[Darren Hart]

A simple test that just confirms the new pthread_condattr_setprotocol_np() API
returns correctly. No priority inversion avoidance testing is done here.

V3: Fix attribution formatting.
V2: Fix copyright in tst-condpi1.c

2010-05-21:  Darren Hart  <dvhltc@us.ibm.com>
	* Makefile (tests): Add tst-condpi1.
	* tst-condpi1.c: New file.
