Change patternsel (LIKE/regex selectivity estimation) so that if there
...
is a large enough histogram, it will use the number of matches in the
histogram to derive a selectivity estimate, rather than the admittedly
pretty bogus heuristics involving examining the pattern contents. I set
'large enough' at 100, but perhaps we should change that later. Also
apply the same technique in contrib/ltree's <@ and @> estimator. Per
discussion with Stefan Kaltenbrunner and Matteo Beccati.

Standardize on using the Min, Max, and Abs macros that are in our c.h file,
...
getting rid of numerous ad-hoc versions that have popped up in various
places. Shortens code and avoids conflict with Windows min() and max()
macros.
