> Move compression/decompression to an encoder specific encoding context

> As part of working on HBASE-5313, we want to add a new columnar
> encoder/decoder. It makes sense to move compression to be part of
> encoder/decoder:
> 1) a scanner for a columnar encoded block can do lazy decompression to a
> specific part of a key value object
> 2) avoid an extra bytes copy from encoder to hblock-writer.
> If there is no encoder specified for a writer, the HBlock.Writer will use a
> default compression-context to do something very similar to today's code.
