patch from qres

I have a patch for babel as used by qres. It was originally written by Scott McKay and Dan Weinreb (RIP), to 1- add support for CESU-8 (as infamously used by Oracle). 2- speed up babel (and measure the speed) Plus by me to 3- support XCVB. I've removed some extraneous type declarations from SWM&DLW, where some other macro already declared a type, and also removed some handling for surrogate codes that was already added upstream since. The patch is attached (against HEAD on github). —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Invent a clever saying, and your name shall live forever. — Anonymous
