It was possible for the code to read out-of-bound data from the
"day_tab" table with some crafted input data. Let's treat these as
invalid input as the month number is incorrect.
A test is added to test this case with a check on the errno returned by
the decoding routine. A test close to the new one added in this commit
was testing for a failure, but did not look at the errno generated, so
let's use this commit to also change it, adding a check on the errno
returned by DecodeDateTime().
Like the other test scripts, dt_test should likely be expanded to
include more checks based on the errnos generated in these code paths.
This is left as future work.
