The latency figure depends on the module implementation.
Instead of using a hardcoded value, each module should be
able to specify its own value. This value is then used
for calculating the minimum buffer size.
Set the nominal latency of the primary (CF) module to a high
value since the virtual device implementation fails CTS tests
if it attempts to pretend that it provides low latency.

alsa_device_proxy keeps a pointer to alsa_device_proxy,
but does not own it. Thus, the lifetime of the proxy must
be no less than of the proxy. In the legacy USB HAL impl
they were stored together (struct alsa_device_info).
Implement an equivalent class (DeviceProxy) in ALSA utils.

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.

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.

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.
