[Piglit] [PATCH v2 02/10] GL3.2 GL_ARB_sync: Test for valid return values from ClientWaitSync

[Nicholas Mack]

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

+/**
+ * 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."
