Davanum Srinivas 5af4478fb2 Add third element to RPC versions for backports ... This makes the RPC version support three elements, adding a "revision" in addition to the major and minor version. The revision would always be zero for the master branch of a service, but could be incremented for stable versions. This provides us some room to backport fixes that affect RPC versions in such a way that would avoid breaking the version lineage for systems running stable versions that may some day be involved in a rolling upgrade to a version from master. I didn't find any tests for version_is_compatible(), so I added some for existing version scenarios, as well as new ones with revisions. They also serve to validate that this doesn't break anything for code using two-element versions (the expectation is that two-element versions will still be used everywhere until a third is needed).
