Add LOCALTIME and LOCALTIMESTAMP functions per SQL99 standard.

Remove ODBC-compatible empty parentheses from calls to SQL99 functions
 for which these parentheses do not match the standard.
Update the ODBC driver to ensure compatibility with the ODBC standard
 for these functions (e.g. CURRENT_TIMESTAMP, CURRENT_USER, etc).
Include a new appendix in the User's Guide which lists the labeled features
 for SQL99 (the labeled features replaced the "basic", "intermediate",
 and "advanced" categories from SQL92). features.sgml does not yet split
 this list into "supported" and "unsupported" lists.

+    <acronym>SQL92</acronym> defined three feature sets for
+    compliance: basic, intermediate, and advanced. Most database
+    products claiming <acronym>SQL</acronym> standards compliance were
+    compliant at only the basic level, since the entire set of
+    intermediate and advanced features was either to voluminous or in
+    conflict with legacy behaviors.

+   <para>
+    <acronym>SQL99</acronym> defines a large set of individual
+    features rather than the ineffectively broad three levels found in
+    <acronym>SQL92</acronym>. We list the entire set of features
+    defined in the standard, with comments on those features not yet
+    implemented in <productname>PostgreSQL</productname>.
