[Piglit] [PATCH 2/8] GL3.2 GL_ARB_sync: Test for valid return values from ClientWaitSync

v2: Fix comments, initialize variables.  Still need to figure out if GPU commands
    needed before testing these.

v3: Rewrite test cases, fix comment and config block and add to all.tests

+ * \file
+ * Test ClientWaitSync() returns correct values
+ *
+ *
+ * Section 5.2.1(Waiting for Sync Objects) of OpenGL 3.2 Core says:
+ * 	"ClientWaitSync returns one of four status values. A return value of
+ * 	 ALREADY_SIGNALED indicates that sync was signaled at the time
+ * 	 ClientWaitSync was called. ALREADY_SIGNALED will always be
+ * 	 returned if sync was signaled, even if the value of timeout is
+ * 	 zero. A return value of TIMEOUT_EXPIRED indicates that the
+ * 	 specified timeout period expired before sync was signaled. A re-
+ * 	 turn value of CONDITION_SATISFIED indicates that sync was signaled
+ * 	 before the timeout expired. Finally, if an error occurs, in
+ * 	 addition to generating a GL error as specified below,
+ * 	 ClientWaitSync immediately returns WAIT_FAILED withoutblocking."
