Break parser functions into smaller files, group together.

Rewrite parser's handling of INSERT ... SELECT so that processing of the SELECT part of the statement is just like a plain SELECT. All INSERT-specific processing happens after the SELECT parsing is done. This eliminates many problems, e.g. INSERT ... SELECT ... GROUP BY using the wrong column labels. Ensure that DEFAULT clauses are coerced to the target column type, whether or not stored clause produces the right type. Substantial cleanup of parser's array support.

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments.

First cut at full support for OUTER JOINs. There are still a few loose ends to clean up (see my message of same date to pghackers), but mostly it works. INITDB REQUIRED!

extern Node *refnameRangeOrJoinEntry(ParseState *pstate,
pgindent run. Make it all clean.

char *refname,
int *sublevels_up);
Change scoping of table and join refnames to conform to SQL92: a JOIN clause with an alias is a <subquery> and therefore hides table references appearing within it, according to the spec. This is the same as the preliminary patch I posted to pgsql-patches yesterday, plus some really grotty code in ruleutils.c to reverse-list a query tree with the correct alias name depending on context. I'd rather not have done that, but unless we want to force another initdb for 7.1, there's no other way for now.

char *relname,
Attr *alias,
bool inh,
bool inFromCl);
Subselects in FROM clause, per ISO syntax: FROM (SELECT ...) [AS] alias. (Don't forget that an alias is required.) Views reimplemented as expanding to subselect-in-FROM. Grouping, aggregates, DISTINCT in views actually work now (he says optimistically). No UNION support in subselects/views yet, but I have some ideas about that. Rule-related permissions checking moved out of rewriter and into executor. INITDB REQUIRED!
