unconditionally disable the octave_allocator class
* configure.ac: Delete the --enable-octave-allocator option.
* oct-alloc.h: Delete octave_allocator class. Warn if file is
included. Unconditionally define macros to be empty.
* NEWS: Make note of these changes.
* oct-alloc.cc: Delete.
* liboctave/util/module.mk (UTIL_SRC): Remove it from the list.
