RFR 8165793 : Provide an API to query if a ClassLoader is parallel capable

[Brent Christian]

Hi,

Please review my fix for 8165793.  This follows the discussion here:
http://mail.openjdk.java.net/pipermail/jigsaw-dev/2016-September/009328.html

The proposal is to add a new public method on ClassLoader:

/**
 * Returns {@code true} if this class loader is
 * {@linkplain #registerAsParallelCapable parallel capable}, otherwise
 * {@code false}.
 *
 * @return  {@code true} if this class loader is parallel capable,
 *          otherwise {@code false}.
 * @since   9
 */
public final boolean isParallelCapable();
