Simone Bordet d39f19cc23 Issue #2429 - Review HttpClient backpressure semantic.
Introduced a Response.DemandedContentListener to explicitly separate
the will to request more content from the notification that the content
has been consumed.

Updated all transports to follow the new semantic: rather than waiting
for the callback to complete before delivering more content, now they
wait for the demand to be positive to deliver more content.

Since now the content may be unconsumed but there can be more demand,
all transport implementation had to be changed to use RetainableByteBuffer
to retain content buffers that were not consumed.
