module working: 1) C_GetFunctionList is always present; 2) fwObject
and fwSession now remember their handles on behalf of the fwInstance;
3) fwSessions are created before mdSessions, so the mdSession can
use the fwSession's arena; 4) finished implementing findObjects;
5) builtin constants are in network byte order; 6) libnssckbi.so
knows about and can pull in its dependencies (e.g. libnssckfw.so,
libnssb.so, and NSPR).
