title: add finalizer support for plain buffers
desc: |-
  Buffers very often need finalizer support because they can contain native
  structures pointing to malloc()'d memory (or socket handles, etc).  Currently
  user code must use an actual object and attach a finalizer for that object.
  
  Adding a fixed finalizer field would add buffer overhead for those buffers
  that don't need finalization which is not ideal (but certainly a reasonable
  approach anyway).
  
  Another approach would be to support finalizers only for dynamic buffers: add
  a flag for "finalizer present" and if the flag is set, store a finalizer
  pointer in the dynamic data area (before or after actual data).
  
  A third approach would be to similarly use dynamic buffers but put the pointer
  in the duk_hbuffer_dynamic struct (depending on whether or not a finalizer is
  needed).  However, this would require user to know beforehand when a finalizer
  is needed because it affects the duk_hbuffer alloc size.
