Remove BSONElement::validate()

            BSONObj o( buf );

>>>  BSONObj.valid() returns false signifying a corrupt BSON object.

            if ( _objcheck && ! o.valid() ) {

                cerr << "size: " << size << endl;

                while ( i.more() ) {

                    BSONElement e = i.next();

                    try {

>>>  e.validate() does not throw an exception and the "NEXT ONE" message is not printed.

                        e.validate();

                    }

>>>  An assertion is triggered on printing "e" (a BSONElement) to standard error. 

                    cerr << "\t " << e << endl;
