Robert Edmonds 7456d16212 t/generated-code2/cxx-generate-packed-data.cc: Fix build failure on newer protobuf
google::protobuf::Message::Reflection has been removed in newer versions
of protobuf. The replacement is google::protobuf::Reflection.

protobuf in commit 779f61c6a3ce02a119e28e802f229e61b69b9046 ("Integrate
recent changes from google3.", from August 2008) changed the following
in message.h:

    -  class Reflection;  // Defined below.
    +  // Typedef for backwards-compatibility.
    +  typedef google::protobuf::Reflection Reflection;

The "typedef for backwards-compatibility" apparently lasted ten years
until protobuf commit 6bbe197e9c1b6fc38cbdc45e3bf83fa7ced792a3
("Down-integrate from google3.", from August 2018) which finally removed
the typedef:

This commit updates the only use of this typedef (in the test suite) to
directly refer to the replacement, google::protobuf::Reflection. This
fixes the build failure in the test suite.

There are two tests.

"test-generated-code" is a simple test that can easily be adapted.
"test-generated-code2" is a comprehensive test.

If you have a quick problem, hack at "test-generated-code";
but i don't want that file to be too hard to navigate,
so you must eventually add a test to "test-generated-code2".

I appreciate additional test cases!
Please submit them as issues in the tracking system, or email me.

Here are the files involved in each test:

test.proto                      Protobuf declarations for the simple test.

test.pb-c.h                     Protobuf-C generated code based on test.proto

test-full.proto                 Protobuf declarations for the exhaustive test.
