DO NOT MERGE: audiopolicy: Remove raw pointer references to AudioMix
AudioInputDescriptor, AudioOutputDescriptor, and AudioSession used
to reference AudioMix instances using a raw pointer. This isn't
safe as AudioMix was owned by AudioPolicyMix, which is not
referenced by descriptors.
Change AudioMix* pointers in Audio{Input|Output}Descriptor and
AudioSession to wp<AudioPolicyMix> which reflects their
relationship correctly.
To ensure that code does not operate on AudioMix instances
independently from AudioPolicyMix, and to avoid introducing
a lot of getter / setter methods into AudioPolicyMix, make
the latter to inherit AudioMix. This makes sense because
AudioPolicyMix is essentially a ref-counted version of AudioMix.
