Subject: Updated set of unit tests and unit test protos. This commit includes
 changes to the C#-specific protos, and rebuilt versions of the "stock"
 protos. The stock protos have been locally updated to have a specific C#
 namespace, but this is expected to change soon, so hasn't been committed.
 Four areas are currently not tested: 1) Serialization - we may restore this
 at some point, possibly optionally. 2) Services - currently nothing is
 generated for this; will need to see how it interacts with GRPC 3) Fields
 beginning with _{digit} - see https://github.com/google/protobuf/issues/308
 4) Fields with names which conflict with the declaring type in nasty ways -
 see https://github.com/google/protobuf/issues/309
