Add guard code to protect from buffer overruns on long date/time input
strings. Should go back in and look at doing this a bit more elegantly
and (hopefully) cheaper. Probably not too bad anyway, but it seems a
shame to scan the strings twice: once for length for this buffer overrun
protection, and once to parse the line.
Remove use of pow() in date/time handling; was already gone from everything
*but* the time data types.
Define macros for handling typmod manipulation for date/time types.
Should be more robust than all of that brute-force inline code.
Rename macros for masking and typmod manipulation to put TIMESTAMP_
or INTERVAL_ in front of the macro name, to reduce the possibility
of name space collisions.
