* keywords.h
Arrange for quote_identifier() and pg_dump to not quote keywords that are unreserved according to the grammar. The list of unreserved words has gotten extensive enough that the unnecessary quoting is becoming a bit of an eyesore. To do this, add knowledge of the keyword category to keywords.c's table. (Someday we might be able to generate keywords.c's table and the keyword lists in gram.y from a common source.) For the moment, lie about WITH's status in the table so it will still get quoted --- this is because of the expectation that WITH will become reserved when the SQL recursive-queries patch gets done. I didn't force initdb because this affects nothing on-disk; but note that a few regression tests have changed expected output.

Add PGDLLIMPORT to ScanKeywords and NumScanKeywords. Per buildfarm, this is now needed by contrib/pg_stat_statements.

Add a function pg_get_keywords() to let clients find out the set of keywords known to the SQL parser. Dave Page

Tweak the core scanner so that it can be used by plpgsql too. Changes: Pass in the keyword lookup array instead of having it be hardwired. (This incidentally allows elimination of some duplicate coding in ecpg.) Re-order the token declarations in gram.y so that non-keyword tokens have numbers that won't change when keywords are added or removed. Add ".." and ":=" to the set of tokens recognized by scan.l. (Since these combinations are nowhere legal in core SQL, this does not change anything except the precise wording of the error you get when you write this.)

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

New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass.
