Remove support for obsolete dumped heaps. Dumping heaps was discontinued 8 years ago, however loading a dumped heap is still supported. This blocks changes and improvements of the malloc data structures - hence it is time to remove this. Ancient binaries that still call malloc_set_state will now get the -1 error code. Update tst-mallocstate.c to just check for this. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
