New year, new copyright, new expected unknown issues with various files that won't be covered by the script and/or will be but shouldn't change. I'll do the details on Jan 1, but would appreciate this being preapproved so I can actually get it merged by then. CHANGELOG_BEGIN CHANGELOG_END

# The main two factors for why we need this are
|
|
|
|
# 1. We only have a source jar for java_proto_library.
|
|
# The rules in bazel-common do not support this.
|
|
|
|
# 2. We need to get the source jar via the JavaInfo provider.
|
|
# The rules in rules_proto do not support this.
|
|
|
|
# We probably want to clean this up and upstream it at some point.
