Summary:
I'm working on deploying haste2 with jest. This updates all the files that require changes for this to work and they are backwards compatible with the current version of jest.
* package.json was just outdated. I think haste1's liberal handling with collisions made this a "non-issue"
* env.js didn't properly set up ErrorUtils, also unsure why that isn't a problem in jest right now already?
* some things were mocking things they shouldn't
* Because of the regex that matches against providesModule and System.import, it isn't possible to list module names more than once. We have multiple tests reusing the same providesModule ids and using System.import with modules that only exist virtually within that test. Splitting up the strings makes the regexes work (we do the same kind of splitting on www sometimes if we need to) and using different providesModule names in different test files fixes the problem. I think the BundlesLayoutIntegration-test is going to be deleted, so this doesn't even matter.

Summary:
Just can't get the point. What does `the next task that might have been queued up earlier` mean? Earlier than what? `The first task`? Please correct me if I missed something.

Summary:
Default behavior should be unchanged.
If we queue up a bunch of expensive tasks during an interaction, the default
`InteractionManager` behavior would execute them all in one synchronous loop at
the end the JS event loop via one `setImmediate` call, blocking the JS thread
the entire time.
The `setDeadline` addition in this diff enables an option to only execute tasks
until the `eventLoopRunningTime` is hit (added to MessageQueue/BatchedBridge),
allowing the queue execution to be paused if an interaction starts in between
tasks, making the app more responsive.
Additionally, if a task ends up generating a bunch of additional tasks
asynchronously, the previous implementation would execute these new tasks after
already scheduled tasks. This is often fine, but I want it to fully resolve
async tasks and all their dependencies before making progress in the rest of the
queue, so I added support for `type PromiseTask = {gen: () => Promise}` to do
just this. It works by building a stack of queues each time a `PromiseTask` is
started, and pops them off the stack once they are resolved and the queues are
processed.
I also pulled all of the actual queue logic out of `InteractionManager` and into
a new `TaskQueue` class to isolate concerns a bit.
