Use longs instead of ints to store pointers in NIO buffers.
This allows the code to be used on 64-bit VMs.

Simplify the nio Buffer implementations, and fix MappedByteBuffer.
* Fix the reported bug caused by delegation in the MappedByteBuffer
implementation.
* Collapse the three classes (ReadOnly*, ReadWrite*, and *) used
to implement most buffer types into one class each.
* Rename HeapByteBuffer to ByteArrayBuffer to match its companions.
* Remove BaseByteBuffer.
* Give the classes used to implement asXBuffer sane names (their
existing names were backwards).

Make OSMemory the semi-supported libcore.io.Memory.
Looks like we're not going to bother with a separate libcore.os package,
when libcore.io will do.

Move the MemoryBlock up into java.nio.Buffer.
This lets me kill getBaseAddress and the (bogus) DirectBuffer interface.

This is just a stepping-stone, not particularly interesting by itself.

Use finalizers to free direct buffers.
Also switch to a cheaper scheme for avoiding double-frees (which could only
happen if library code is broken; at the moment the only caller is the
iovec-style stuff). This halves the cost of direct buffer access, at the
unimportant cost of not throwing an exception if we try to access a buffer
we freed while we still had a reference to it.
Also use named constants for the sizes of primitive types.
Also kill BufferFactory.

Minor nio speedups (scalar operations only).
This patch speeds up nio scalar operations for all types larger than byte.
Basically just by trimming fat, pushing any byte-swapping down into Java,
and adding a boolean field to ByteOrder that basically caches the "do we
need byte swapping?" comparison.
For the worst case, byte-swapped doubles, this patch gives a 2x speedup.
At the other end of the spectrum, for native-order chars and shorts, this
patch gives a 20% speedup. Still, that's not bad for quite a reduction in
code.
Now I've tidied this up a bit, I have more of a plan. This is just the warmup.

Some nio tidying.
Remove indirection on OSMemory, and use public ByteOrder and MapMode types
throughout the implementation, rather than adding our own duplication. Also
remove some unnecessary Java methods that just forwarded to identical native
methods, and an unnecessary factory class for MappedByteBuffer instances.
Also get rid of ICommonDataTypes, most of which was unused cruft.
