Possible crash on disconnect with streams using Oboe sample rate conversion

[philburk]

If a stream was opened using setSampleRate() and the setSampleRateConversionQuality() was not None,
then if a headset was plugged in or unplugged,
and another thread or the user closed the stream,
then it was possible to get a crash in oboe_aaudio_error_thread_proc().

Note that this bug could also occur if any of these other conversion functions were enabled:

builder.setChannelConversionAllowed(true);
builder.setFormatConversionAllowed(true);

To avoid this bug, use Oboe v1.9.0 or later.

Note that the bug was due to not using shared_ptr when calling builder->openStream().
Because it is so dangerous, we are disabling the openStream(AudioStream **streamPP)
method. It was deprecated a long time ago. Now if you call it you will get an error and no stream.

The root cause was because the AudioStreamBuilder.openStream() was not using a shared_ptr
when creating a child stream. buggy code

Using a shared_ptr is necessary to prevent an error callback from using a raw pointer and referencing a deleted stream.
It also prevents the stream from being deleted while a data callback is active.
