Bug 1251210 - In configure.py, take AUTOCONF from the environment, if set there. r=ted At the same time, remove the (useless and wrong) check for AUTOCONF in old-configure.in (wrong because it very likely is picking autoconf > 2.5).

 * Used to enumerate over elements defined by its implementor.
 * Although hasMoreElements() can be called independently of getNext(),
 * getNext() must be pre-ceeded by a call to hasMoreElements(). There is
 * no way to "reset" an enumerator, once you obtain one.
 * @version 1.0

interface nsISimpleEnumerator : nsISupports {
   * Called to determine whether or not the enumerator has
   * any elements that can be returned via getNext(). This method
   * is generally used to determine whether or not to initiate or
   * continue iteration over the enumerator, though it can be
   * called without subsequent getNext() calls. Does not affect
   * internal state of enumerator.
   * @see getNext()
   * @return true if there are remaining elements in the enumerator.
   *         false if there are no more elements in the enumerator.
  boolean hasMoreElements();

   * Called to retrieve the next element in the enumerator. The "next"
   * element is the first element upon the first call. Must be
   * pre-ceeded by a call to hasMoreElements() which returns PR_TRUE.
   * This method is generally called within a loop to iterate over
   * the elements in the enumerator.
   * @see hasMoreElements()
   * @throws NS_ERROR_FAILURE if there are no more elements
   *                          to enumerate.
   * @return the next element in the enumeration.
