> Simplify Codec Buffer Allocation

> Some performance testing of another product highlighted some weirdness to me
> in Avro library. In particular the way that blocks are
> compressed/decompressed in {{DeflateCodec}}.
> For each block of raw data, it is compressed/decompressed into a new buffer.
> That new buffer is then immediately written out to disk. Well, that buffer
> is requested by the caller with a requested size, but it's a bit odd because
> the buffer is cached, so only the first call has any affect. Also, that
> buffer is expanded as needed, but then is maintained at that size for the
> life of the application, it is never resized smaller, so it could hold that
> large (underutilized) buffer for awhile.
> Finally, even if the requested size was working as expected, the "requested"
> size is quite dubious. Right now, the requested size is equal to the size of
> the raw block, which means that the buffer requested for a decompress will
> always be too small and the buffer created for a compression will always be
> too big. Instead, I propose that we just fix a sensible default value for
> all buffers.
