Several builtin functions are incorrectly exposed through the JDBC escaped function syntax
{fn <function_call>}
---------------------------------------------------------------------------------------------------------------

         Key: DERBY-591
         URL: http://issues.apache.org/jira/browse/DERBY-591
     Project: Derby
        Type: Bug
    Versions: 10.0.2.0, 10.1.1.0    
    Reporter: Daniel John Debrunner
    Priority: Minor


Due to lack of direction in the way functions are added into the parser, any functions that
are added into the parser's miscBuiltinsCore are also automatically JDBC/ODBC escaped functions.

E.g. the new XML functions (e.g. XMLPARSE), COALESCE, VALUE etc. etc.

The correct set of escaped scaler functions is defined in appendex C (C1- C5)  of JDBC 3.0.

Discovered this while trying to make the JDBC escape functions table driven, at least for
the valid subset of table driven functions added in DERBY-475.

Probably just need to split the miscBuiltins core into two functions, one for functions that
are SQL and allowed in JDBC escape, and one for ones only allowed in SQL.
