RFR 8201317: X25519/X448 code improvements (xs)

[Xuelei Fan]

As you are already there, would you mind describe the differences 
between multByInt() and mult()?

For method description, the comment is normally start with "/**" for 
javadoc friendly.

Previously, you have the comment:
    // must work when a==r
Do you want to keep it somehow?

Otherwise, looks fine to me.
