Frequency to SampleRate and channels to channelCount.
-Added channelCount(), changed everything to use this instead
of channels() in QAudioFormat class.
-Added setSampleRate() and sampleRate(), changed everthing to use these
instead of setFrequency() and frequency() in QAudioFormat class.
-Added supportedSampleRates() and supportedChannelCounts(), changed
everything to use these instead of supportedFrequencies() and
supportedChannels() in QAudioDeviceInfo class.
