Implement reference counting of scope records. * elf/dl-close.c (_dl_close): Remove all scopes from removed objects from the list in objects which remain. Always allocate new scope record. * elf/dl-open.c (dl_open_worker): When growing array for scopes, don't resize, allocate a new one. * elf/dl-runtime.c: Update reference counters before using a scope array. * elf/dl-sym.c: Likewise. * elf/dl-libc.c: Adjust for l_scope name change. * elf/dl-load.c: Likewise. * elf/dl-object.c: Likewise. * elf/rtld.c: Likewise. * include/link.h: Inlcude <rtld-lowlevel.h>. Define struct r_scoperec. Replace r_scope with pointer to r_scoperec structure. Add l_scoperec_lock. * sysdeps/generic/ldsodefs.h: Include <rtld-lowlevel.h>. * sysdeps/generic/rtld-lowlevel.h: New file. * include/atomic.h: Rename atomic_and to atomic_and_val and atomic_or to atomic_or_val. Define new macros atomic_and and atomic_or which do not return values. * sysdeps/x86_64/bits/atomic.h: Define atomic_and and atomic_or. Various cleanups. * sysdeps/i386/i486/bits/atomic.h: Likewise.
