Rename DriverInterface::getPosition -> refinePosition. This reflects
the fact that the driver may provide more precise position, however
this is an optional operation.
Rename StreamIn/Out::mContext -> mContextInstance. This is
to emphasize that StreamIn/Out actually own the context and they
hold the real context instance, not just a reference/pointer
to it, like other classes involved in the inheritance chain.

Since in the C and HIDL APIs the method for opening a stream
receives the device to connect to, some legacy HAL implementations
took an advantage of that. In AIDL APIs device port connection
process is more dynamic and independent of the stream creation.
To simplify porting of legacy implementations to AIDL, a helper
class StreamSwitcher is added. It emulates the legacy behavior
by allowing to postpone the stream implementation creation until
the connected device is known. Until that moment, it exposes
to the client a stub implementation of the stream interface.

Moving frame counter to the StreamContext class enables
switching stream drivers on the fly while keeping the frame
count monotonically increasing.
StreamWorkerCommonLogic now holds a pointer to StreamContext,
which makes redundant storing copies of the fields of the latter.

Since the client may end up never retrieving the interface
instance for sending it over Binder, postpone setting
of the scheduler policy to until that very moment.
Rename 'ChildInterface::getPtr' to 'getInstance' for clarity.

* changes:
audio: Move StreamContext ownership out from StreamCommonImpl
audio: Use ChildInterface in StreamCommonImpl
audio: Update StreamAlsa and alsa utils for built-in devices
audio: Simplify and extend alsa::Mixer
Upcoming implementations of the streams of the primary module
will need to change the underlying stream type depending on
the current connected device. The stream context must persist,
thus its life time must be bound to the IStreamIn/Out implementation.
Move the StreamContext instance under ownership of StreamIn/Out.
Add StreamCommonImpl::onClose so that the owner of the context
may know when it is safe to reset it.
Re-arrange the order of the arguments when creating a stream
so that the context always comes first.

Replace the pair of 'shared_ptr<>, Binder' with

Fix logging of returned sub-objects to print their

Remove alsa::MixerControl. tinyALSA contains utility
functions for setting values in percents, they use
the same logic as used to be there for handling
the "volume" control. Use access serialization at
the mixer level, rather than for each control.
Move the call to 'mixer_open' to alsa::Mixer.
Add controls for capture (mic) mute and gain. They
will be used by the primary HAL.

When a vendor HAL reuses libaudioserviceexampleimpl,
a subclass of Module cannot change Configuration.
This change adds virtual method Module::initializeConfig(),
then a vendor HAL can override it to load custom Configuration.

This is a method which can be optionally implemented
by a stream in case it can provide more exact position,
for example by taking into account data in intermediate
buffers.
Implemented this method for StreamAlsa and StreamRemoteSubmix.
