1) Take use of some safe macros
2) Remove duplicate tests stat06
3) Add ELOOP check
4) Remove useless struct member

- * Test Name: stat03
- *
- * Test Description:
- *   Verify that,
- *   1) stat(2) returns -1 and sets errno to EACCES if search permission is
- *      denied on a component of the path prefix.
- *   2) stat(2) returns -1 and sets errno to ENOENT if the specified file
- *	does not exists or empty string.
- *   3) stat(2) returns -1 and sets errno to EFAULT if pathname points
- *	outside user's accessible address space.
- *   4) stat(2) returns -1 and sets errno to ENAMETOOLONG if the pathname
- *	component is too long.
- *   5) stat(2) returns -1 and sets errno to ENOTDIR if the directory
- *	component in pathname is not a directory.
- *
- * Expected Result:
- *  stat() should fail with return value -1 and set expected errno.
- *
- * 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)
- *   	if errno set == expected errno
- *   		Issue sys call fails with expected return value and errno.
- *   	Otherwise,
- *		Issue sys call fails with unexpected errno.
- *   Otherwise,
- *	Issue sys call returns unexpected value.
- *
- *  Cleanup:
- *   Print errno log and/or timing stats if options given
- *   Delete the temporary directory(s)/file(s) created.
- *
- * Usage:  <for command-line>
- *  stat03 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
- *	where,  -c n : Run n copies concurrently.
- *		-e   : Turn on errno logging.
- *		-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.
