Added new funcs to QAudioFormat and QAudioDeviceInfo class's.

QAudioFormat::setChannelCount(), channelCount()
QAudioFormat::setSampleRate(), sampleRate()
QAudioDeviceInfo::supportedChannelCounts(), supportedSampleRates()
Changed all instances to use these new functions instead of
channels(),frequency(),setFrequency(),setChannels()
supportedChannels(),supportedFrequencies()
Old functions still exist but are marked obsolete.
