  talloc_reference(context, ptr) adds a new context to ptr so ptr is
  now effectively parented by two parents. The two parents are not
  equal however because a talloc free(ptr) will remove the reference
  first and then the original parent.

  This causes problems here because we create the packet_header with
  self->buffer as a context. However other code takes references to it
  - pinning it to other parents. If we did a
  talloc_free(self->packet_header) here we would be removing those
  references _instead_ of freeing the ptr from our own self->buffer
  reference. This will cause both memory leaks (because we will not be
  freeing packet_header at all, and later crashes because important
  references will be removed.

  When references begin to be used extensively I think we need to
  start using talloc_unlink instead of talloc_free everywhere.
