Core HAL changes:
1. Add StreamPrimary implemented via StreamAlsa.
2. Align the configuration with the HIDL HAL.
3. Fix position retrieval vs. standby call.
4. Fix sleeps in StreamAlsa.
VTS changes:
1. Use several bursts for stream I/O test scenarios that check
observable position increase. This is because the position may
not be available until a couple of transfers have been made.
2. Do not require position increase for the scenarios that do
not make several bursts. As specified above, the position may
not have been increased for the ALSA case. Whereas, using
multiple bursts in all scenarios will increase test time, and
make the state machine transitions graph more complicated.
3. Hook up the test config file to shut down audioserver during
VTS tests, fix the test config file.

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.

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.

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.

This method is used to bring out the hardware from standby.
It replaces the ad hoc 'exitStandby' method in StreamUsb.
Streamlined StreamUsb code to avoid locking during transfers.
Updated StreamRemoteSubmix to use 'start'.
Added extra checks to StreamStub to ensure that 'init/shutdown'
and 'standby/start' methods are called as expected. This allows
removing extra checks from non-stub stream implementations.

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

Simplify the experience of implementing stream variants.
Stream class now exposes two interfaces: DriverInterface
and StreamCommonInterface, which represent the two
aspects of its usage: via the FMQ on the worker thread,
and via IStreamCommon Binder interface.
Input/output streams now inherit the concrete stream
variant, and implement interface methods specific for
IStreamIn and IStreamOut.
Added DriverInterface::shutdown method which is called
on the worker thread prior to the exit.

Plumb propagation of errors reported by the implementations
of DriverInterface::setConnectedDevices up to the Module.
This allows returning the reported errors from the corresponding
IModule interface methods. Implement handling of errors
from connection state update by the Module implementation.
When updating streams about the connection status
ensure that the list of connected devices is not empty.
Also, add an extra check to AudioStreamIn#ActiveMicrophones
to validate the size of the returned active microphones
list.

1. By default, the DriverUsb should be standby. When there is data
transfer request, it will exit standby.
2. Initialize alsa device profile before reading device info.
3. Open the alsa device proxy after the preparation succeed.

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.
