This patch introduces a new class, SuffixStrategy and two sub-classes,
SuffixContent and SuffixManifest which allow to independently assign
suffixes to contents and manifests respectively. The produce() function
in socket_producer.cc has also been changed to use them.
Given a strategy and an offset (and optionally the capacity of a
manifest), these classes automatically compute the correct next
suffixes for both type of data (manifest or content). This removes
the burden of having to manage suffixes for instance when producing
or when retrieving content, and could be expanded to add more
strategy in the future.
Currently the only existing strategy is "INCREMENTAL": manifests
with capacity N have a suffix multiple of N+1: 0, N+1, 2(N+1) etc.
Contents have a suffix incremented by 1 except when it conflicts
with a manifest: 1, 2, ..., N, N+2, N+3, ..., 2N+1, 2N+3...
