Add basic UTF-8 helper functions
Add utf8_width() and utf8_strwidth() which can be used to calculate the display width of a single character or a string, respectively. A lookup table is used to spot double width characters, as well as composing characters. There currently isn't any code to deal with ambigious characters.
