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

/* Ideas:
- Generalize run length encoding + index for all tables
- remove redundant tables for ID_start, ID_continue, Case_Ignorable, Cased
Case conversion:
- use a single entry for consecutive U/LF runs
- allow EXT runs of length > 1
Decomposition:
- Greek lower case (+1f10/1f10) ?
- allow holes in B runs
- suppress more upper / lower case redundancy
