Fix extraction of week and quarter fields from intervals.
"EXTRACT(WEEK FROM interval_value)" formerly threw an error.
Define it as "tm->tm_mday / 7". (With C99 division semantics,
this gives consistent results for negative intervals.)
"EXTRACT(QUARTER FROM interval_value)" has been implemented
all along, but it formerly gave extremely strange results for
negative intervals. Fix it so that the output for -N months
is the negative of the output for N months.
Per bug #18348 from Michael Bondarenko and subsequent discussion.
