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).
