	* elf/dl-open.c (_dl_global_scope_alloc): Make global.
	(dl_open_worker): Use realloc, not malloc to resize array.
	* elf/rtld.c (_dl_initial_searchlist): New variable.
	(_dl_main): Copy content of _dl_main_searchlist to
	_dl_initial_searchlist.
	* elf/ldsodefs.h: Add declarations for _dl_initial_searchlist and
	_dl_global_scope_alloc.
	* elf/Versions [libc, GLIBC_2.1]: Add _dl_initial_searchlist.
	* elf/dl-close.c (_dl_close): When removing object with global
	scope remove allocated searchlist if no dynamically loaded object
	is on it anymore.
	* elf/dl-support.c (_dl_initial_searchlist): Renamed from fake_scope.
	(_dl_global_scope, _dl_main_searchlist): Use _dl_initial_searchlist.

	* malloc/mtrace.c (tr_where): Don't print space in location string,
	print it afterwards.  Print better symbol name information.
