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.

Fix exprTypmod to recognize length-coercion function expressions, such as bpchar(char_expression, N), and pull out the attrtypmod that the function is coercing to. This allows correct deduction of the column type in examples such as CREATE VIEW v AS SELECT f1::char(8) FROM tbl; Formerly we labeled v's column as char-of-unknown-length not char(8). Also, this change causes the parser not to insert a redundant length coercion function if the user has explicitly casted an INSERT or UPDATE expression to the right length.
