Vinayakumar B updated HDFS-8019:

Attachment: HDFS-8019-HDFS-7285-01.patch

Draft implementation of ByteBufferManager.

Almost same logic as ByteArrayManager, 
except, this manages ByteBuffers and have option to specify whether to manage 
native or heap buffers.

As of now separate managers need to be created for native and heap buffers.

This patch is just for initial review and feedback.
