auto-fill-mode bug in chinese-gbk coding system [with patchs]

[Zhang Wei]

While the coding system is set to chinese-gbk or chinese-gb18030,
auto-fill-mode won't work properly. 

The `nospace-between-words' property does not put on
chinese-gbk/chinese-gb18030 charsets properly to eliminate the "extra
SPACE" problem when refilling. 

And the "fill-find-break-point-function" does not put on
chinese-gbk/chinese-gb18030 charsets properly to make them find line
breaking point properly. 

Here's a patch for "lisp/international/characters.el":
