[svn-r13210] Purpose: Adding test

Description:
    - Added a brief test for DSetCreatPropList::setSzip.  More through tests
      will be added later.
    - Moved check_values from dsets.cpp into h5cpputil.cpp for sharing
      with other tests.

Platforms tested
    AIX 5.1 (copper)
    SunOS 5.8 64-bit (sol)
    Linux 2.6 (kagiso)

+ * Function:	check_values
+ *
+ * Purpose:	Checks a read value against the written value.  If they are
+ *		different, the function will print out a message and the
+ *		different values.  This function is made to reuse the code
+ *		segment that is used in various places throughout
+ *		the test code.  Where the C version of this code segment 
+ *		"goto error," this function will return -1.
+ *
+ * Return:	Success:	0
+ *
+ *		Failure:	-1
+ *
+ * Programmer:	Binh-Minh Ribler (using C code segment for checking values)
