Update.

	* include/stdio.h: Add new parameter to __path_search.
	* libio/oldtmpfile.c: Add 0 as new parameter to __path_search.
	* stdio-common/tmpfile.c: Likewise.
	* stdio-common/tmpfile64.c: Likewise.
	* stdio-common/tmpnam.c: Likewise.
	* stdio-common/tmpnam_r.c: Likewise.
	* stdio-common/tempnam.c: Add 1 as new parameter to __path_search.
	* sysdeps/posix/tempname.c: Add new parameter.  If value is nonzero
	consider TMPDIR environment variable and dir parameter.  Otherwise not.
	* stdio-common/Makefile (tests): Add tst-tmpnam.
	* stdio-common/tst-tmpnam.c: New file.
