When a user calls sbt exit and there is an active background job, sbt
may not exit cleanly. This was primarily because the
background job service shutdown method depended on the
StandardMain.executionContext which was closed before the background job
service was shutdown. This was fixable by reordering the resource
closing in StandardMain.runManaged.
When running a main method, if the user inputs ctrl+c then the `run`
task will exit but the main method is not interrupted so it continues
running even once sbt has returned to the shell. If the main method is a
webserver, this prevents run from ever starting again on a fixed port.
To fix this, we can modify the waitForTry method to stop the job if an
exception is thrown (ctrl+c leads to an interrupted exception being
thrown by waitFor).
I rework the BackgroundJobService so that the default implementation of
waitForTry is now usable and no longer needs to be overridden. The side
effect of this change is that waitFor may now throw an exception. Within
sbt, waitFor was only used in one place and I reworked it to use
waitForTry instead. This could theoretically break a downstream user who
relied on waitFor not throwing an exception but I suspect that there
aren't many users of this api, if any at all.
This PR includes the values of the `description` and `homepage`
settings into the `ivy.xml` files generated by the `makeIvyXml`
task. It restores the behaviour of sbt 1.2.8 and if `useCoursier`
is set to `false`.
Two things are changed in this PR:
* `IvyXml.content` now adds the `homepage` attribute to the
`description` element if `project.info.homePage` is not empty.
* `CoursierInputsTasks.coursierProject0` now fills the previous
empty `CProject.info` field with the description and homepage.

This is a reimplementation of `--addPluginSbtFile`. #4211 implemented the command to load extra `*.sbt` files as part of the global plugin subproject. That had the unwanted side effects of not working when `.sbt/1.0/plugins` directory does not exist. This changes the strategy to load the `*.sbt` files as part of the meta build.

To demonstrate [-Yno-lub](http://eed3si9n.com/stricter-scala-with-ynolub), this shows the code changes that removes lubing (Not all subprojects are done).
After I made the changes, I switched the Scala back to normal 2.12.10.
The current injection of the new nio keys will overwrite any definitions
of those keys in a build source. This is undesirable. The fix is to
create a mapping of scoped keys to settings and for each inject setting
key, if there is a previous key, put that definition after the injected
definition so that it can override it.
It is still possible for progress threads to leak so shut them down if
there are no active tasks. The report0 method will start up a new thread
if a task is added.
In some circumstances, sbt would generate a number of task progress
threads that could run concurrently. The issue was that the TaskProgress
could be shared by multiple EvaluateTaskConfigs if a dynamic task was
used. This was problematic because when a dynamic task completed, it
might call afterAllCompleted which would stop the progress thread. There
also was a race condition because multiple threads calling initial could
theoretically have created a new progress thread which would cause a
resource leak.
To fix this, we modify the shared task progress so that the `stop()`
method is a no-op. This should prevent dynamic tasks from stopping the
progress thread. We also defer the creation of the task thread until
there is at least one active task. This prevents a thread from being
created in the shell.
The motivation for this change was that I found that sometimes there was
a leaked progress thread that would make the shell not really work for
me because the progress thread would overwrite the shell prompt. This
change fixes that behavior and I was able to validate with jstack that
there was consistently either one or zero task progress threads at a
time (zero in the shell, one when tasks were actually running).
When running sbt -Dtask.timings=true, the task timings get printed to
the console which can overwrite the shell prompt. When we use a logger,
the timing lines are correctly separated from the prompt lines.
The completions were generating page numbers that didn't make sense if
there were a small number of scripted tests. For example, suppose that
there were only two tests defined, it would generate *1of3 *2of3 and
*3of3 completions even though there weren't even three tests.
