Enforce cube dimension limit in all cube construction functions
contrib/cube has a limit to 100 dimensions for cube datatype. However, it's not enforced everywhere, and one can actually construct cube with more than 100 dimensions having then trouble with dump/restore. This commit add checks for dimensions limit in all functions responsible for cube construction. Backpatch to all supported versions. Reported-by: Andrew Gierth Discussion: https://postgr.es/m/87va7uybt4.fsf%40news-spur.riddles.org.uk Author: Andrey Borodin with small additions by me Review: Tom Lane Backpatch-through: 9.3
