An inbound channel handler that copies byte buffers onto the JVM heap
and gives them a deterministic lifecycle. This handler also makes sure to
use the unpooled byte buffer (regardless of what channel's allocator is) as
its destination thereby defining a clear boundaries between pooled and unpooled
environments.

Note
If your protocol manages ref-counting or if you are delegating ref-counting
to application space you don't need this handler in your pipeline. Every
other use case needs this handler or you will with very high probability
incur a direct buffer leak.
,
This handler recognizes both ByteBuf's and ByteBufHolder's (think of HTTP
messages extending ByteBufHolder's in Netty).
,
If the input buffer is not readable it's still guaranteed to be released
and replaced with EmptyByteBuf.
