ByteBuffer: Use |offset| directly.
Calling arrayOffset will throw for buffers that are read only.
This fixes FileChannelTest#testReadOnlyByteArrays and
BufferTest#testPutByteBuffer.
Also contains some pedantic trailing whitespace removal.

Fix ByteBuffer performance regression.
Use libcore.io.Memory.memmove for mmaped ByteBuffer and
non-bytearray-backed direct ByteBuffer#put(ByteBuffer)
operations.

Fix BufferTest#testFreed.
Each DirectByteBuffer now has a MemoryRef object associated with it.
This MemoryRef is shared across its duplicates and slices.
Also contains a few other surrounding cleanups :
- FileChannelImpl now allocates the DirectByteBuffer directly.
- Removed a pointless constructor from DirectByteBuffer.
- Removed unnecessary (pos << 0) shifts.

Modify get|putArray methods in ByteBufferAs*Buffers
This will improve the performance of ByteBufferAs*Buffers. The past
implemention was making independent get and set calls for each element
of the array which resulted in the poor performance. The new
implementation uses Memory methods to handle the requests.

Modify getters/setters of ByteBufferAs*Buffers
Added a different set of methods in DirectByteBuffer and HeapByteBuffer
to handle request from the ByteBufferAs*Buffers. The getters and setters
in ByteBufferAs*Buffer check limits instead of getters and setters of
Heap/DirectByteBuffer, therefore it becomes easier to maintain
local properties.
The change avoids making an extra copy of Heap/DirectByteBuffer at
the time of initialization.

Fix DirectByteBufferAlignment
and also an issue which was causing problems while accessing
ByteBufferArray when the buffer was created as duplicate/slice of a
duplicate/slice. A unit test was added for the same.

FollowUp fixes for ByteBuffer
There were some issues caused after changes #815174, #815055,
#815164. Fixes include - using the correct constructor for deprecated
classes, issues with readonly flag, offset for sliced bytebuffer,
introducing isAccessible flag in place of isFreed flag, provided a
method to set accessible flag.

Replace unSafe methods from DirectByteBuffer
Replaced unsafe memory allocation with Memory Class. Also, changed
getter and setter methods to use memory insead of unsafe methods. The
change has provided backing array for the direct byte buffers and memory
accesses using memory methods would improve performance.

Use OpenJdk implementation of java.nio.*
- Unsafe: add more supporting methods.
- NIOAccess / NIOUtils : Track OpenJdk implementation.
- Bits : Initialize byte-order inline.
- Buffer : Add elementSizeShift.
- ByteBuffer : Add stub implementations of setAccessible and
isAccessible for use by the frameworks.
