malloc: Sync dynarray with gnulib

Browse Source 
It syncs with gnulib version a8bac4d49.  The main changes are:

  - Remove the usage of anonymous union within DYNARRAY_STRUCT.
  - Use DYNARRAY_FREE instead of DYNARRAY_NAME (free) so that
    Gnulib does not change 'free' to 'rpl_free'.
  - Use __nonnull instead of __attribute__ ((nonnull ())).
  - Use __attribute_maybe_unused__ instead of
    __attribute__ ((unused, nonnull (1))).
  - Use of _Noreturn instead of _attribute__ ((noreturn)).

The only difference with gnulib is:

--- glibc
+++ gnulib

  abort ();

It seems a wrong sync from gnulib (the code is used on loader and
thus it requires __libc_fatal instead of abort).

Checked on x86_64-linux-gnu.
