It often takes a long time to fix a flake; meanwhile it takes a lot of
time for sheriffs to identify whether to register a new flake for a
failure.
This CL adds automatic identifies identification of one know flake type.
Once identified, it rewrites the error so that:
1. Flakes clustering tool that has only rudimentary clustering, places
all flakes of this kind in the same cluster (not multiple ones like
now). This is a step towards using clustering tool for monitoring
flakes;
2. Sheriff immediately sees that the issue is known.

There is some unknown to me logic in Launcher that sometimes duplicates
the long-press event . This causes flakes whenTAPL expects one long
press, but the actual sequence is 2 events.
That duplication logic seems to be related to race conditions is is hard
to repro. For now, just removing long-press verification. I'll start
with more deterministic events.

Getting events is an expensive operation involving reading logcat. We
did this al least twice even if the number of events was already
sufficient. Fixing this.

Investigation of TAPL failures, especially flakes is complex, partially
because it’s hard to tell whether it’s Launcher who is wrong or the
system.
We need to introduce a framework that looks at Launcher interaction with
the system and reports when interactions deviate from the expected
course, and who made the first wrong step.
This is first, proof-of-concept CL.
It analyzes long-press events. We had multiple cases when long-presses
didn’t happen or happened unexpectedly.
Launcher registers the events, TAPL retrieves and compares against the
sequence of expected regular expressions. This diagnostic is used when
something fails and at the end of public methods.

Clients of BaseSwipeDetector are required to call finishedScrolling(),
which calls setState(IDLE). An obvious place to call this is in
onDragEnd(), which itself is called from a setState(SETTLING). If the
client does this, then the SETTLING state actually clobbers the IDLE
state, leading to undefined behavior. The reason we don't see this in
practice is because we usually call finishedScrolling() after an
animation from onDragEnd() instead of calling it immediately.
To fix this, we add a simple queue such that any calls to setState()
while one is in progress have to wait and are executed in turn. This
ensures we get all the proper state callbacks and end in the correct
one.
Also fix an incorrect call in AbstractStateChangeTouchController which
was masked by this bug. We were calling setState(IDLE) in onDragStart(),
which only worked because the original setState(DRAGGING) incorrectly
clobbered this. Now we only setState(IDLE) (via finishedScrolling())
when we fully clear the state, i.e. when the interaction is finished.
Test: added testInterleavedSetState

In scenarios like: atest NexusLauncherOutOfProcTests against the
platform built from command line, and Launcher from the platform, we are
not failing now, and @Stability treats it as a PLATFORM_POSTSUBMIT run.

In a879f9c481, the ub-launcher-aosp-tapl
was switched from current to system_current. Since Launcher3Tests links
against this library, we require it to use the system stubs as well.
But I broke the check in the build system while doing some cleanup, so
we never noticed. I'm fixing the check in:

AS installs tests in such a way that they don't get necessary
permissions; the result is a long message starting with "Failed to get
system health diags" when a test fails.
While I'm looking for a good solution, removing this annoyance.

I suspect that some tests using TAPL run under pressure (mem or CPU,
created either intentionally or as a result of a leak somewhere)
where test process may generate a pause between DOWN and MOVE events
enough to be recognized as a long tap, which opens a context menu
instead of swiping.
While the clean solution is b/140252325, this is a workaround.

Logging assertion failures.
Modifying waits for condition to avoid timing out the whole test if the
iteration takes too long in favor of failing with an actionable diag.
