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.

Extract code interacting with tinyALSA which is not
specific to USB into "abstract" module and stream
implementations ModuleAlsa and StreamAlsa. Also, move
utility code which does not need module or stream
context into Utils.
This facilitates implementation of the CF core HAL which
also uses tinyALSA, allowing to share common code.

Since specializations of the 'Module' class likely need
to provide their own specializations for streams, provide
virtual methods for them.

Make interface methods protected so that subclasses can
augment them.
Provide getters for private fields.

Instead of relying on the device type, use the 'AudioPort.flags'
field to determine the device direction.
Remove 'isUsbInputDeviceType' and 'isUsbOutputtDeviceType'
as they are too specific to particular device type and just
add a maintenance burden.

1. The card and device must be specified before reading device info.
2. Map PcmType::FIXED_Q_8_24 to PCM_FORMAT_S24_LE.
Map PcmType::INT_24_BIT to PCM_FORMAT_S24_3LE.

These utilities are for types generated from AIDL. Since
the types end up in the 'aidl' namespace (NDK backend), it makes
sense to keep the utilities in the same namespace.
While changing the namespace, I've found numerous useless
includes of 'Utils.h' and removing them, also reorganizing
lists of includes along the way to match the style guide.
