* 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.
