[PATCH] Don't use GLIBC_PRIVATE errno outside of libraries

[Andreas Schwab <schwab at suse dot de>]

Now that IN_LIB is always defined while building a library, this is easy
to fix.

Andreas.

	[BZ #14142]
	* include/errno.h: Redefine errno only if !NOT_IN_libc || IN_LIB.
	* include/netdb.h: Likewise for h_errno.
	* elf/tst-stackguard1.c: Include <tls.h>.

	* tst-cancel14.c: Include <sys/time.h>.
	* tst-cancel15.c: Likewise.
	* tst-mutex9.c: Include <stdint.h>, <stdlib.h> and <sys/time.h>.
	* tst-stackguard1.c: Include <tls.h>
