    simple: Improve pa_simple_read() documentation
    
    There was a question in IRC about whether pa_simple_read() blocks or
    not. It's already documented on the simple API overview page, but it's
    good to say it also in the function reference. As a bonus, I added
    some additional details to the documentation too.
