Обсуждение: backpatch of datetime fixes

I've backpatched Thomas's fixes for the potential buffer overruns in
the datetime code to the REL7_2_STABLE branch. The required changes
are pretty minimal, and the code passes the regression tests.

However, I haven't yet seen a test-case that demonstrates the buffer
overrun in 7.2 code (I originally found the problem when playing with
datetime on 7.3-dev with integer datetimes) -- I've tested it a little
bit and it seems to work, but this patch probably requires pretty
widespread testing.

Cheers,

Neil

I've had trouble provoking an error also, but the circumstances should
be related to having a long date/time input, especially if it has more
fields than one would expect in a valid date/time string.
