Fixes#1458
Running sbt from `/` results to sbt getting stuck trying to load the directories recursively, and eventually erroring with a java.lang.OutOfMemoryError (after freezing for a long time) even on an Alpine container.
To prevent it, this adds a check to see if the absolute path is `/` or not.
```
/ $ sbt -Dsbt.version=1.4.0-SNAPSHOT
[error] java.lang.IllegalStateException: cannot run sbt from root directory without -Dsbt.rootdir=true; see sbt/sbt#1458
[error] Use 'last' for the full log.
```
There have been a number of complaints about the new classloader closing
behavior. It is too aggressive about closing classloaders after test and
run. This commit softens the behavior by allowing a classloader to be
resurrected after close by creating a new zombie classloader that has
the same urls as the original classloader. After this commit, we always
close the classloaders when we are done, but they can still leak
file descriptors if a zombie is created.
To configure the behavior, I add the allowZombieClassLoaders key. If it
is false (which is default), we will warn but still allow them. If it
is true, then we silence the warning. In a later version of sbt, we can
change the semantics to be strict.
I verified after this change that I could add a shutdown hook in `run`
and it would be evaluated so long as I set `bgCopyClasspath := false`.
Otherwise the needed jars were deleted before the hooks could run.
Bonus: delete unused ResourceLoaderImpl class
Fixes#5070
This adds a new setting called `includePluginResolvers` (default `false`).
When set to `true`, it the project will include resolvers from the metabuild.
This allows the build user to declare a resolver in one place (`project/plugins.sbt`) that gets applied to both the metabuild as well as all the subprojects. The scenario comes up when someone distributes a software on their own repo. Ref #4103
We want to recursively monitor the project meta build, but we also want
to avoid listing directories that don't exist. To compromise, I rework
the buildSourceFileInputs to add the nested project directories if they
exist. Because the fileInputs are a setting, this means that adding a
new project directory and *.sbt or *.scala will not immediately trigger
a rebuild, but in most common cases, it will. I added a scripted test
for this.
In sbt 1.3.0, we only monitor build sources in the root project
directory and the root project meta build directory. This commit adds
these inputs for each project.

This was an oversight that caused consoleQuick to not work with
supershell. We should probably try to figure out a way to allow custom
tasks to black list themselves from super shell reporting.
We have seen failures in scripted to create the output file for streams
and it has also been reported in https://github.com/sbt/sbt/issues/5067.
I believe this may caused by the same stream output being initialized by
multiple tasks. To fix this, I add locking on a per-file basis. There
was (and is) additional synchronization on the Streams _instance_, but
the per-file locks are stored in the Streams companion object so the
locking should be honored no matter which Streams instance calls make.
I also skip the call to IO.touch if the file already exists. I believe
that this is the common case and since IO.touch was being called with
setModified = false, it should be fine to skip the touch when the file
exists.
Prior to this change, I was able to induce the issue in #5067 in roughly
1/50 of calls to `scripted actions/cross-multiproject`. I wasn't able to
reproduce after this change.
In https://github.com/sbt/sbt/issues/5075 we realized that sbt 1.3.0
introduces a regression where it closes the classloader used to invoke
the main method for in process run before all of its non-daemon threads
have terminated. To fix this and still close the classloader, I add a
method, runInBackgroundWithLoader that provides the background job
services with an optional classloader that it can close after the job
completes.
This cleanly merges and works with 1.3.x as well.
https://github.com/sbt/sbt/issues/5075 reports that sbt 1.3.0 has a
regression for in process run. In sbt 1.3.0, we close the classloader
that invokes the main method before all of the daemon threads complete.
This adds a scripted test that fails due to this regression.

When setting swoval.tmpdir via globalBase, changed to set globalBase as absolute path.
`com.swoval.runtime.NativeLoader.loadPackaged` uses `java.lang.System.load`.
It requires absolute path, so we should set `swoval.tmpdir` with absolute path.
During refactoring, these warnings got out of date. I also added
scaladoc to the watchTriggeredMessage key.
Ref: https://github.com/sbt/sbt/issues/5051.
To avoid reliance on jvm global variables, we need to share the super
shell state with each of the console appenders that write to the console
out. We only set the progress state for the console appenders for the
screen. This prevents messages that are below the global logging level
from modifying the progress state without preventing them from being
written to other appenders.
The ability to set the ProgressState for each of the console appenders
is added in a companion util PR.
I verified that the test output of io/test was correctly written to the
streams after this change (there were no progress lines in the output).
Ref https://github.com/sbt/sbt/issues/4911. This names each parallel
test task with the name of the task so that supershell can display it.
It only applies for parallel tests. When run sequentially, supershell
will still display executeTests.
Disabling supershell when color mode is disabled is a sensible default
(especially for piped output). However, I think it should still be
possible to use supershell in no color mode.
This requires a util change that also enables supershell in no color
mode.
