  Adds ast_escape_encoded utility to properly handle escaping of quoted field before uri.

  This commit backports a feature in trunk affecting initreqprep so that display name won't
  be encoded improperly. Also includes unit tests for the ast_escape_quoted function.
  This patch gives 1.8 a much improved outlook in countries which don't use standard
  ASCII characters.
