This is a small hack to make it easier for me to identify when a
schema change occurs in the upstream Gerrit Code Review project.
By making the constant public, the Google infrastructure glue can
setup a compile-time rule against this value by saying:
private static final Schema_61 C = SchemaVersion.C;
javac will fail when the upstream version changes, reminding the
developers at Google to check what has happened upstream and make
sure the database will support those changes.
The current version must now be edited in two places on the same
line, as the compile-time check requires the constant's variable
type to match the value.
