Don't use INTDEF/INTUSE with __cxa_atexit (bug 14132). 

This patch removes use of the obsolete INTDEF/INTUSE mechanism for
__cxa_atexit, replacing it with libc_hidden_def/libc_hidden_proto.

Tested for x86_64 that installed stripped shared libraries are
unchanged by the patch.

	[BZ #14132]
	* stdlib/cxa_atexit.c (__cxa_atexit): Use libc_hidden_def instead
	of INTDEF.
	* include/stdlib.h (__cxa_atexit_internal): Remove declaration.
	(__cxa_atexit): Use libc_hidden_proto.
	[!NOT_IN_libc] (__cxa_atexit): Remove macro definition.
