  Log Message:
  -----------
  Update TAL/METAL implementation:

- move to METAL 1.1, including the macro extension feature

- integrate various maintenance patches from the Zope 3 trunk intended
  to reduce the difference between the Zope 2 and Zope 3
  implementations of page templates

This update merges the following revisions from the trunk:

Revision 37825:
  add the FasterStringIO to replace the basic StringIO, so this matches the
  Zope 2 code and gets a tiny bit faster as well

Revision 37830:
  correct a broken comment, and expand with useful information

Revision 37939:
  - add a comment about a mysterious instance variable
  - remove an unused assignment statement
  - simplify an expression assignment

Revision 37944:
  changed the macro stack entries to have meaningful attribute names so
  references to individual fields are easier to decipher

Revision 38008:
  repair outdated comment

Revision 38009:
  "surface" portion of the move to METAL 1.1: macro extension requires the
  extend-macro attribute instead of use-macro, and cannot be combined with
  use-macro

Revision 38010:
  update comment based on the move to extend-macro

Revision 38012:
  fix the semantics of macro extension to match the METAL 1.1 specification

Revision 38013:
  note the move to METAL 1.1
