LUCENE-4995: Don't hold references on large decompression buffers in 
CompressingStoredFieldsReader.

CompressingStoredFieldsReader now only reuses an internal buffer when there is
no more than 32kb to decompress. For large blocks, a dedicated decompression
buffer will be created on demand.
                
> Remove the strong reference of CompressingStoredFieldsReader on the 
> decompression buffer

> CompressingStoredFieldsReader has a strong reference on the buffer it uses 
> for decompression. Although it makes the reader able to reuse this buffer, 
> this can trigger high memory usage in case some documents are very large. 
> Creating this buffer on demand would help give memory back to the JVM.
