Improve libunicode and libregexp headers (#288)
- move all `lre_xxx` functions to libunicode
- use flags table `lre_ctype_bits` instead of bitmaps
- simplify `lre_is_space`, `lre_js_is_ident_first` and `lre_js_is_ident_next`
- simplify `simple_next_token`, handle UTF-8 correctly
- simplify `is_let`, remove dead code
