pg_controldata: Prevent division-by-zero errors
If the control file is corrupted and specifies the WAL segment size
to be 0 bytes, calculating the latest checkpoint's REDO WAL file
will fail with a division-by-zero error. Show it as "???" instead.
Also reword the warning message a bit and send it to stdout, like the
other pre-existing warning messages.
Add some tests for dealing with a corrupted pg_control file.
