High memory use in H264TrackImpl. Use a MappedByteBuffer where possible.

[GoogleCodeExporter]

I have attached a patch in the form of an SVN diff. It includes a changes to 
getSamples() on the Track interface:

    List<Sample> getSamples();

Performance tests of the attached patch reduce memory use significantly. Note 
that it has not been tested extensively. It will also require minor changes to 
any applications that call getSamples(), i.e., to get the ByteBuffer, use:

getSamples().get(0).getByteBuffer()

I hope this can be incorporated into the main code base.

I have not included any changes to test code or related project code, but these 
fixes should be fairly simple.

OK, that was missing some files. Give this one a go.

I tried this one, OutOfMemoryException is gone. Looks very good!

Sebastian, Anton, can this be incorporated into the main code base?

There is a quite sophisticated memory map algo in place so this is no longer an 
issue
