Save customized values in alphabetic order. Do it fast.

For xemacs-21.5. The patch makes `custom' save variables and faces in alphabetic order. It also improves custom-save-... to work about 2-3 times faster. Thanks to Adrian, he put the patch under thorough testing. Still it would be greate if someone try it in xemacs-21.5.
