chmod03 and chmod04 test on file and directory with same logic, so
combine them together.

- * Test Name: chmod03
+/*\
+ * [DESCRIPTION]
  *
- * Test Description:
- *  Verify that, chmod(2) will succeed to change the mode of a file
- *  and set the sticky bit on it if invoked by non-root (uid != 0)
- *  process with the following constraints,
- *	- the process is the owner of the file.
+ * Verify that, chmod(2) will succeed to change the mode of a file/directory
+ * and set the sticky bit on it if invoked by non-root (uid != 0) process with
+ * the following constraints:
+ *	- the process is the owner of the directory.
  *	- the effective group ID or one of the supplementary group ID's of the
- *	  process is equal to the group ID of the file.
- *
- * Expected Result:
- *  chmod() should return value 0 on success and succeeds to change
- *  the mode of specified file with sticky bit set on it.
- *
- * Algorithm:
- *  Setup:
- *   Setup signal handling.
- *   Create temporary directory.
- *   Pause for SIGUSR1 if option specified.
- *
- *  Test:
- *   Loop if the proper options are given.
- *   Execute system call
- *   Check return code, if system call failed (return=-1)
- *   	Log the errno and Issue a FAIL message.
- *   Otherwise,
- *   	Verify the Functionality of system call
- *      if successful,
- *      	Issue Functionality-Pass message.
- *      Otherwise,
- *		Issue Functionality-Fail message.
- *  Cleanup:
- *   Print errno log and/or timing stats if options given
- *   Delete the temporary directory created.
- *
- * Usage:  <for command-line>
- *  chmod03 [-c n] [-e] [-f] [-i n] [-I x] [-p x] [-t]
- *     where,  -c n : Run n copies concurrently.
- *             -e   : Turn on errno logging.
- *             -f   : Turn off functionality Testing.
- *	       -i n : Execute test n times.
- *	       -I x : Execute test for x seconds.
- *	       -P x : Pause for x seconds between iterations.
- *	       -t   : Turn on syscall timing.
- *
- * HISTORY
- *	07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS:
- *  This test should be run by 'non-super-user' only.
- *
+ *	  process is equal to the group ID of the directory.
