Update. 

* stdlib/canonicalize.c (canonicalize): Rename to __realpath and
	don't define static.  Remove old __realpath function.  TC1 of
	POSIX 2001 will allow the second parameter to be NULL.
	* stdlib/test-canon.c: Comment out test for NULL as second
	parameter of realpath.

	* time/offtime.c (__offtime): Set errno if overflow is detected.
