  (svn_pool_create_ex): Reorganise to have separate definitions for
  APR_POOL_DEBUG set or unset.  The APR_POOL_DEBUG set version calls
  svn_pool_create_ex_debug, rather than svn_pool_create_debug, as the
  latter does not exist.
  (svn_pool_create_ex_debug): Add an APR_POOL_DEBUG set version of this
  function.  The APR_POOL_DEBUG unset version calls svn_pool_create_ex,
  rather than svn_pool_create, so that the allocator can be passed.
