Change audio worker threads priority to ..._URGENT_AUDIO to match
the coupled thread in the audio flinger.
Set SCHED_FIFO scheduler for FAST threads (also to match AF fast
mixer/capture threads). In order to enable that, grand SYS_NICE
capability to the HAL service process and provide "getTid"
function in the StreamWorker class. For testing, add a "FAST"
output to the "stub" module in the HAL configuration.

for the HAL service process during VTS test. For regular
"reader"/"writer" threads should see 'NI 19, PRI 38',
for FAST "writer" should see 'NI -19, PRI 43, RTPRIO 3, SCH 1'

In tests, it is possible that the worker exits quickly,
prior to the moment when the thread controller begins
waiting for it to start. Improper handling of this case
was causing intermittent lock-ups of VTS tests.

This is intended for use in tests where the worker
just executes some actions and then exits by itself.
Use of 'join' instead of 'stop' ensures that the
worker goes through all actions.

Fix the mistake of making StreamWorker to inherit
from the part which provides actual thread logic (Impl).
The lifetime of the logic object must be longer
than the lifetime of the StreamWorker's thread.
Otherwise, the thread could still have running while
the logic has already been destroyed (consider
the order of destructors in C++ class inheritance).
With this fix, the StreamWorker class does not have
to be a template anymore, thus reorganize the code
to move big methods into a .cpp file.

Enhance the return type of the 'workerCycle' to allow it
exiting without inducing an error on the controller side.
Also, put StreamWorker into a namespace.

Audio threads need to be able to set their priority.
Also, traditionally these worker threads set a custom
thread name. Implement this functionality in StreamWorker.
Since initialization steps can fail, implement simple
error reporting via a string field `mError`. The state
of the string field replaces the dedicated `ERROR` worker
state.

This utility class has been copied from HIDL VTS.
It will be used both for the default implementation
and AIDL VTS, and might need modifications.
