* elf/dladdr.c: Remove #include <setjmp.h>, we don't use it.
* shlib-versions: Set libdl=2.
* elf/dl-deps.c (_dl_map_object_deps): Use a linked list of alloca'd
elements and then scan it to fill the single malloc'd array, instead
of using realloc to grow the array in the first pass. _dl_map_object
may do some mallocs that break our stream of reallocs, and the minimal
realloc can't handle that.
* elf/dl-init.c (_dl_init_next): Take argument, link_map whose
searchlist describes the piece of the DT_NEEDED graph to be
initialized.
* elf/link.h: Update prototype.
* sysdeps/i386/dl-machine.h (RTLD_START): Pass _dl_loaded as argument
to _dl_init_next.
* sysdeps/m68k/dl-machine.h: Likewise.
* elf/dl-deps.c (_dl_open): Pass new object as arg to _dl_init_next.
* elf/link.h (struct link_map): Add `l_reserved' member, soaking up
extra bits in last byte.
* elf/dl-deps.c (_dl_map_object_deps): Use that for mark bit to avoid
putting dup elts in search list.
* elf/dlclose.c: Use MAP->l_searchlist to find deps to close.
* elf/dlsym.c: Don't tweak linked list. Scope array given to
_dl_lookup_symbol does the right thing.
