[bug-libunistring] Detecting word breaks one by one

[Aleksander Morgado]

Hi Bruno & all,

I was wondering if instead u8_wordbreaks() where the whole input string
is processed looking for wordbreaks, it would be possible to have a new
method to find just 'the next' wordbreak position.

This would help cases where for example there's a maximum number of
words to detect, as the whole string doesn't need to be processed. And
also wouldn't therefore need allocation of a new array just to store the
flags.

Cheers!
