These patches make it possible to use a stream's original sample format without resampling when the avoid-resampling option is set to a sink or a source if the sample format is supported by alsa driver.
In the first patch, it is added to check supported sample formats of a sink or source in a similar way of getting supported rates. The last patch has some logics to consider sample format including reinitialization of size information when it is needed.
