Mark __dso_handle as hidden [BZ #18822]
Since __dso_handle is always defined by either crtbegin.o from GCC or
dso_handle.c, it should be marked as hidden and be passed directly.

	[BZ #18822]
	* dlfcn/modatexit.c (foo): Remove __dso_handle check.
	* dlfcn/modcxaatexit.c: Include <dso_handle.h>.
	(__dso_handle): Remove declaration.
	* dlfcn/tstatexit.c (__dso_handle): Removed.
	(main): Don't check __dso_handle.
	* dlfcn/tstcxaatexit.c (__dso_handle): Removed.
	(main): Don't check __dso_handle.
	* include/dso_handle.h: New file.
	* malloc/mtrace.c: Include <dso_handle.h>.
