It would be very useful to add an X500Principal(InputStream) constructor
which reads an ASN.1 DER encoded X500Name from the InputStream and leaves
the pointer at the next available byte in the InputStream. More often than not,
a user will be reading the contents of an X.509Certificate from an
InputStream - having a constructor that reads the X500Name from anywhere
in the stream is very useful.

Here's the proposed javadoc:

    /**
     * Creates an <code>X500Principal</code> from an <code>InputStream</code>
     * containing the distinguished name in ASN.1 DER encoded form. The read
     * position of the input stream is positioned to the next available byte
     * after the encoded distinguished name.
     *
     * @param inStream an <code>InputStream</code> containing the distinguished
     * name in ASN.1 DER encoded form
     * @throws IOException if an encoding error occurs (incorrect form for DN)
     */
    public X500Principal(InputStream inStream) throws IOException

Also, I think the InputStream needs to support mark() so that the stream
can be reset() if there are errors.
