* sysdeps/unix/opendir.c (__opendir): Pass extra argument to
__alloc_dir.
(__alloc_dir): Only close descriptor on error if new parameter is true.
* sysdeps/unix/fdopendir.c (fdopendir): Pass extra argument to
__alloc_dir. Don't close fd on error.
* include/dirent.h (__alloc_dir): Adjust prototype.
* include/sys/mman.h (__mremap): Add ellipsis.
* malloc/memusage.c: Adjust mremap wrapper for optional additional
parameter.
