We were using the number of channels actually used by audio devices as
the maximum channel count. This is wrong as CoreAudio can automatically
split or merge channels in order to accommodate the device.
We now assume all channel configurations are valid.

The CoreAudio plugin code in QtMultimedia had several different places
where an array was allocated with "new[]" and deleted with "delete".
Fixed by deleting with "delete[]".

This fixes the issue that when we use QSoundEffect we dont need to get
permission to use the microphone. This was because we were defaulting
to PlayAndRecord. Now we only switch to the PlayAndRecord category when
we try and use an input device.
[ChangeLog][QtMultimedia][iOS] Using QSoundEffect (or SoundEffect in
QML) no longer requires permission to use the microphone.

There is an assumption in QtMultimedia that the first audio device
returned by QAudioDeviceInfo::availableDevices is the default device, so
we must make an effor to make sure this is true. This commit should fix
the issue on OS X.

QAudioOutput::setVolume stopped working for CoreAudio when it was ported
to live in it's own plugin. This was because it was not possible to set
the volume of QAudioOutput in iOS. Now the functionality has been
restored and added for iOS as well. For OS X we use the old method of
setting the volume property of the AudioUnit. On iOS it is not possible
to set the volume on a per AudioUnit basis, so we now manually modify
the buffer contents (the same we do for QAudioInput already).

The available sample rates for a given device are the nominal sample
rates reported by the device. It is possible to use other sample rates
and CoreAudio will take care of the conversion. So what we will do is
report what rates are available for a device, but not explicitly require
those sample rates to have a valid format.

Only the maximum number of channels was reported as being supported.
We now report all possible configurations up to the maximum number of
channels to be supported.
