/**
   A typesafe replacement for DYNAMIC_ARRAY.
   We use MEM_ROOT for allocating storage, rather than the C++ heap.
   The interface is chosen to be similar to std::vector.

@remark
   Unlike DYNAMIC_ARRAY, elements are properly copied
   (rather than memcpy()d) if the underlying array needs to be expanded.

@remark
   Depending on has_trivial_destructor, we destroy objects which are
   removed from the array (including when the array object itself is destroyed).

@remark
   Note that MEM_ROOT has no facility for reusing free space,
   so don't use this if multiple re-expansions are likely to happen.

@param Element_type The type of the elements of the container.
          Elements must be copyable.
   @param has_trivial_destructor If true, we don't destroy elements.
          We could have used type traits to determine this.
          __has_trivial_destructor is supported by some (but not all)
          compilers we use.
