*   Adds a family= attribute in `tf.summary` ops to allow controlling the tab
    name used in Tensorboard for organizing summaries.
*   When GPU is configured, do not require --config=cuda, instead, automatically
    build for GPU if this is requested in the configure script.
*   Fix incorrect sampling of small probabilities in CPU/GPU multinomial.
*   Add a list_devices() API on sessions to list devices within a cluster.
