* elf/dl-error.c (_dl_signal_error): Store information about use of

	real malloc in the catch object.
	(_dl_catch_error): Forward information about malloc use to caller
	in new parameter.
	(_dl_out_of_memory): Make static.
	* elf/dl-deps.c: Adjust callers of _dl_catch_error.
	* elf/dl-libc.c: Likewise.
	* elf/dl-open.c: Likewise.
	* elf/rtld.c: Likewise.
	Add new --audit option.
	* sysdeps/generic/ldsodefs.h: Remove _dl_out_of_memory declaration.
	(rtld_global_ro._dl_signal_error): Add new parameter.
	* include/dlfcn.h (_dl_catch_error): Add new parameter.
	* dlfcn/dlfcn.c (_dlerror_run): Pass additional parameter to
	_dl_catch_error.  Only free if the returned newly value says so.
