Mike Spreitzer 7d5430cfba Fix extra latency and add tests for that and width 
Added missing dispatching after delayed release of seats.

Updated logging for all six situations of execution completion and
seat release.

Added behavioral tests for non-zero extra latency and non-unit width.

Also added two tests for baseline functionality.

Also improved some comments and other logging in `queueset.go`.

Mike Spreitzer 8c2108bc80 Refactor goroutine counting 
Add comment outlining TestContextCancel.

Stop calling `t.Errorf` from wrong goroutine.

Package up queueNoteFn expectation checking.

Add counting of goroutine in req1 exec fn.

Remove unnecessary assignment to `_`.

Make TestContextCancel wait on fake clock, to insulate timing check
from scheduler noise.

Factor goroutine counting out of queueset.go, into queueset_test.go,
where it matters.

Refactor promise: Use a simple channel-based implementation for normal
code, a mutex-based one for testing code.

Took all the panics out of queueset.go

Shrink the timeouts in promise tests to 1 second.

Mike Spreitzer 904cd74454 Some cleanup of the package for event clocks 
Rename from `clock` to `eventclock`.

Simplify by removing the prohibition on an EventFunc suspending and
resuming activity.

Remove "EventClock" from names to avoid stuttering.

Start to consolidate test code under fairqueuing/testing/.

Mike Spreitzer 0c550377cf Introduce event clocks based on k8s.io/utils/clock 
So we can move off of the apimachinery clock package.

Switch queueset to new clocks.

Removed event clocks based on apimachinery clocks,
because this PR introduces ones based on k8s.io/utils/clock .

Removed interface that is implemented by only one interesting type.

Simplify RealEventClock::EventAfterTime.
