Thanks for the feedback!

- I have replaced "Warning" with WARNING".
- I have changed the API of CancelBackup() to return void.
I don't use the return code anyway, and I guess it's less confusing
and "strange" that way.
- I have added comments to disambiguate pg_stop_backup() and CancelBackup().

CancelBackup now writes a message to the server log if it cannot delete
backup_label - I hope that's not too verbose...
