The reason why this is optional is that the feature requires huge
mapping tables and I don't think every user need the feature.

In linux.h there were some #undef HAVE_INT_TIMEZONE, which are useless
because HAVE_TM_ZONE overrides it anyway, and messing with configure
results isn't cool.

Removed multibyte stuff since client does not know about encoding in the backendFixed quoting bug reported by Sascha Demetrio (sd@b-comp.de).

subqueries.  It passes the normal 'runcheck' tests, and I've tried
a few simple things like
  select 1 as foo union (((((select 2))))) order by foo;

There are a few things that it doesn't do that have been talked
about here at least a little:

1) It doesn't allow things like "IN(((select 1)))" -- the select
here has to be at the top level.  This is not new.
2) It does NOT preserve the odd syntax I found when I started looking
at this, where a SELECT statement could begin with parentheses.  Thus,
  (SELECT a from foo) order by a;
fails.

I have preserved the ability, used in the regression tests, to
have a single select statement in what appears to be a RuleActionMulti
(but wasn't -- the parens were part of select_clause syntax).
In my version, this is a special form.

This may cause some discussion: I have differentiated the two kinds
of RuleActionMulti.  Perhaps nobody knew there were two kinds, because
I don't think the second form appears in the regression tests. This
one uses square brackets instead of parentheses, but originally was
otherwise the same as the one in parentheses.  In this version of
gram.y, the square bracket form treats SELECT statements the same
as the other allowed statements.  As discussed before on this list,
psql cannot make sense out of the results of such a thing, but an
application might.  And I have designs on just such an application.

on pghackers.  Arrange for the sort ordering of general INET values
to be network part as major sort key, host part as minor sort key.
I did not force an initdb for this change, but anyone who's running
indexes on general INET values may need to recreate those indexes.

ExecutorRun.  This allows LIMIT to work in a view.  Also, LIMIT in a
cursor declaration will behave in a reasonable fashion, whereas before
it was overridden by the FETCH count.
