 Boost.MPI has some special archivers (e.g., ignore_skeleton_oarchive) that
 ignore some of the structural aspects of serializing data. It does so by
 recognizing attempts to serialize values of type collection_size_type and
 version_type and then silently ignoring them which, in the narrow domain
 that ignore_skeleton_oarchive is used, works well. The current crop of
 failures in the MPI library (skeleton_content_test-* are failing
 sporadically) all appears due to inconsistent use of
 collection_size_type/version_type.

 The attached patch updates the serialization library to use
 collection_size_type and version_type consistently. Tests pass for GCC and
 Clang with both the Serialization and MPI libraries, and this ends up
 fixing a pretty serious regression in the MPI library.

 Currently, Boost.MPI is broken on both trunk and the release branch
 because
