Public function builder interface.
The parser (sql/sql_yacc.yy) uses a factory / builder pattern to
construct an <code>Item</code> object for each function call.
All the concrete function builders implements this interface,
either directly or indirectly with some adapter helpers.
Keeping the function creation separated from the bison grammar allows
to simplify the parser, and avoid the need to introduce a new token
for each function, which has undesirable side effects in the grammar.
