Release Note

<!-- markdown -->

As of HBase 3.0, the ByteBufferUtils class is now marked as a Private API for internal project use only. Downstream users are advised that it no longer has any compatibility promises across releases.

As of earlier HBase release lines the class is now marked as deprecated to call attention to this planned transition.

Description

Came up in 1.5.0RC2 checking that we broke API on ByteBufferUtils during HBASE-20716 by removing a method.

The whole class looks like internal utility stuff. Not sure why it's IA.Public; has been since we started labeling the API.

This ticket tracks clean up

1) Make it IA.Private in master/3.0
2) Mark it deprecated with an explanation that it'll be Private in 3.0 on branch-2 and branch-1
3) Add back in the missing method for branches prior to master/3.0
