hurdmalloc: Run fork handler as late as possible [BZ #19431]
This is the hurd-specific follow-up for 29d794863cd6e03115d3670707cc873a9965ba92 : hurdmalloc also needs the same fix * hurd/hurdmalloc.c (malloc_fork_prepare): Rename to _hurd_malloc_fork_prepare. (malloc_fork_parent): Rename to _hurd_malloc_fork_parent. (malloc_fork_child): Rename to _hurd_malloc_fork_child. (_hurd_fork_prepare_hook): Drop malloc_fork_prepare. (_hurd_fork_parent_hook): Drop malloc_fork_parent. (_hurd_fork_child_hook): Drop malloc_fork_child. * hurd/hurdmalloc.h (_hurd_malloc_fork_prepare, _hurd_malloc_fork_parent, _hurd_malloc_fork_child): Add declarations. * sysdeps/mach/hurd/fork.c (__fork): Call __malloc_fork_lock_parent after locking locks (notably hurd_dtable_lock). Call _hurd_malloc_fork_prepare after that. Call _hurd_malloc_fork_parent before __malloc_fork_unlock_parent and _hurd_malloc_fork_child before __malloc_fork_unlock_child.
