[BZ #3429]
* elf/dl-open.c (dl_open_worker): Keep holding dl_load_lock until
we are sure we do not need it anymore for _dl_close. ALso move
the asserts inside the lock region.

body macro.

them.

sizes in main arena.

[BZ #3352]
* elf/dl-minimal.c (realloc): Let malloc() return a new pointer,
and use memcpy() if it does.
components which lack them.

at least one entry consisting of the parameter concatenated with
the domain.
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.
