Subject: [PATCH] testback.c: add some missing 'const'.

This source file isn't actually built as part of even a test binary,
so it hasn't been kept up to date with internal API changes. But it
might still come in useful in the future (I think its original purpose
was to substitute for a normal backend in order to test the GUI side
of a new PuTTY port before the network side was written), so I'll at
least try to carry on keeping it updated.
