  ** handlers could be used with two completely different data sources (for
  ** example, a parser and a visitor over in-memory objects).  This decoupling is
  ** the most important feature of upb, because it allows parsers and serializers
  ** to be highly reusable.
  **
  ** This is a mixed C/C++ interface that offers a full API to both languages.

  /* A upb::Sink is an object that binds a upb::Handlers object to some runtime

   *
   * TODO(haberman): right now all of these functions take selectors.  Should they
   * take selectorbase instead?
   *
   * ie. instead of calling:
   *   sink->StartString(FOO_FIELD_START_STRING, ...)
   * a selector base would let you say:
   *   sink->StartString(FOO_FIELD, ...)
   *
   * This would make call sites a little nicer and require emitting fewer selector
   * definitions in .h files.
   *
   * But the current scheme has the benefit that you can retrieve a function
   * pointer for any handler with handlers->GetHandler(selector), without having
   * to have a separate GetHandler() function for each handler type.  The JIT
   * compiler uses this.  To accommodate we'd have to expose a separate
   * GetHandler() for every handler type.
   *
   * Also to ponder: selectors right now are independent of a specific Handlers
   * instance.  In other words, they allocate a number to every possible handler
   * that *could* be registered, without knowing anything about what handlers
   * *are* registered.  That means that using selectors as table offsets prohibits
   * us from compacting the handler table at Freeze() time.  If the table is very
   * sparse, this could be wasteful.
   *
   * Having another selector-like thing that is specific to a Handlers instance
   * would allow this compacting, but then it would be impossible to write code
   * ahead-of-time that can be bound to any Handlers instance at runtime.  For
   * example, a .proto file parser written as straight C will not know what
   * Handlers it will be bound to, so when it calls sink->StartString() what
   * selector will it pass?  It needs a selector like we have today, that is
   * independent of any particular upb::Handlers.
   *
