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>. (mtrace): Pass __dso_handle directly. * nptl/pthread_atfork.c: Include <dso_handle.h>. (__dso_handle): Remove declaration. (__pthread_atfork): Pass __dso_handle directly. * nptl/tst-atfork2mod.c: Include <dso_handle.h>. (__dso_handle): Removed. * posix/wordexp-test.c: Include <dso_handle.h>.
