As WA currently supports either a single logcat dump after each job,
or fixed rate polling of logcat, it is possible that the fixed size
logcat buffer wraps around and overwrites data between each dump or
poll. This data may be used by output processors that should be
notified of the loss.
This change allows the detection of buffer wrapping by inserting a
known log entry into the buffer, although it cannot say how much data
was lost, and only applies to the "main" logcat buffer.
If buffer wrap is detected, a warning is logged by WA.
- Add copyright headers to files that did not already have them
- Update the year to the last year the file was modified in files with
existing headers.
Rename the `start` method to `run` as this is what is what is called
by the threading module's `start` method, otherwise this causes the
polling to be done in the main thread blocking execution.
- Workload's update_result stage has now been broken up into two parts:
extract_results and update_output. This is to allow the assistant to
pull output from the target in between the two stages.
- Updated assistant implementations for Linux and Android targets from
the exisiting code.
- Extended target descriptor code to handle assistants and their
parameters as well.
- Updated the target manager to actually make use of the assistants.
