Wrong hyperlinks in class references: QAudioInput/QAudioOutput

Issue
Clicking on AudioInputExample::stateChanged() [slot] jumps to QAudioInput::stateChanged() [signal]. Similar for QAudioOutput.

Probable cause
The example slots, introduced in Qt 5.0 docs, share the same name as class signals (e.g. AudioInputExample::stateChanged() vs. QAudioInput::stateChanged())

Suggestion
Change the slot names (e.g. to handleStateChange()), for multiple reasons:

1. Remove wrong hyperlink
2. Prevent reader confusion – remove ambiguity from "stateChanged()"
3. Follow existing signal/slot naming conventions – signal names tend to be "reports" in past tense (e.g. QSlider::valueChanged()), whilst slot names tend to be "actions" in present tense (QSlider::setValue()).
