This lets us remove the unmaintained StackWalker library and its hacky
upstream_utils script.
@Gold856 reported that StackWalker gives blank stacktraces:

Jackson is a very heavy library; it supports loads of features that we
don't need, and historically has caused issues due to long class loading
times (a little over 2 seconds to load AprilTagFieldLayout). This often
manifests as a help request in the form of "my robot disables when I do
X, but doesn't disable when doing X in subsequent attempts until code
restart." While SC has brought down Jackson loading times significantly,
with AprilTagFieldLayout loads taking only 330 milliseconds, that's
still a rather long delay, and while libraries should handle any JSON
loading ahead of time to prevent delays in auto/teleop, it would still
be good to make the worst case better to reduce user frustration.
Benchmarks indicate using [Avaje
Jsonb](https://github.com/avaje/avaje-jsonb) to load AprilTagFieldLayout
only takes ~70 ms, a fair chunk of which isn't actually in Avaje Jsonb
(~4 ms is spent on using getResourceAsStream to retrieve the JSON file,
~8 ms is spent on just loading the AprilTag class and its dependencies).
Note that all times listed are end-to-end, meaning nothing else was done
except for the operation being benchmarked, and doing arithmetic on them
can be flawed due to some classes being loaded twice, i.e.,
getResourceAsStream and `new AprilTag()` likely load some of the same
JDK classes and so subtracting both from the Avaje Jsonb load time is
likely slightly incorrect because class loading is being double counted.
For our purposes, it's likely accurate enough and is mostly just for
contextualization.
Benchmarks were run on a Raspberry Pi CM5 with 2 GB of RAM. Source code
for the
[results](https://github.com/user-attachments/files/26471452/benchmark.txt)
can be found in the "Fastjson2" commit
(2456d15ca8ebd17635e607cd40bf8816e77869a1).
Avaje Jsonb uses code generation via annotation processors to generate
the classes needed to do JSON serde and uses service providers to find
them, which will require downstream changes in robot projects, as the
different service providers in each library must be merged together for
Avaje Jsonb to function. We will use the Gradle shadow plugin, as its
already used by the installer and therefore adds zero additional
dependencies.
Also fixes the google compile-testing library to 0.23.0 (the latest
available at time of writing) instead of a wildcard
Jackson versions were inconsistent across projects; most were on 2.19.2,
but the fields subproject was on 2.15.2. All projects are now on 2.19.2
for consistency
SourceLink embeds the git repo and hash into the pdbs, which allows VS to get the source files exactly matching a pdb directly from github.
Only VS and WinDbg are supported currently, but there are issues in the vscode tools repo to enable it there.
4.9 will be needed for some things being added to a few of our plugins. It adds the new lazy configuration tasks which help a good amount in some cases.

Updated to gradle 3.2.1. This also moves all of the task graph listeners for dependency setup to use the gradle model, making it both safer and reducing line count.
Updates the gradle version to 2.14. In doing so, some model elements have changed. Additionally, some redundant elements have been removed from the gradle scripts.
This is a major restructuring of the WPILib repository to simply build
procedures and remove the remnants of Maven from everything except the
eclipse plugins. Gradle files have been largely simplified or rewritten,
taking advantage of splitting up parts of the build into separate build
files for ease of reading.
The eclipse plugins are now in a separate project, as is ntcore. All
dependencies are resolved via Maven dependencies, with the
Jenkins-maintained WPILib repo. Project structures have also been
simplified: we no longer have separate subprojects inside wpilibc and
wpilibj. Where possible, these changes hav been done with git renames,
to make sure we still have full history for all repositories. Other
unrelated subprojects have also been broken out: OutlineViewer is now a
separate project.

This updates our Gradle wrapper to version 2.5. The Gradle update
requires no changes to developer systems.

This adds gradle support for building wpilibj and wpilibc. At this
point, both of these libraries should be fully ready to go.
Gradle should give us a number of improvements, including less
dependencies for getting building up and running, and MUCH faster build
times. I'm noticing significantly faster build times already compared to
Maven, with neither system building the plugins. The changes here should
be pretty straight forward. The basic command for gradle is './gradlew'.
This is the gradle wrapper, and it will find and download the correct
gradle executable for your system. There is no need to install anything
yourself. To see every task available, run './gradlew tasks'. The
important tasks for us are listed under the WPILib header when the tasks
command is run. To generate unit test binaries, the
fRCUserProgramExecutable command will create the C++ tester, and the
wpilibjIntegrationTestJar command will create the Java tester. The Jenkins
deploy scripts have been modified to know the difference between maven
generated and gradle generated jars with an environment variable. Creating
the eclipse plugins still requires Maven, but gradle will handle calling
it correctly and generating the proper dependencies for it. Create the
plugins by calling ./gradlew eclipsePlugins.
Jenkins can now be modified to support the new build system. Unit tests
are run with ./gradlew test. Generating the integration tests uses the
above two commands, and then process proceeds exactly as it did before.
For publishing documentation, a new task has been created, ./gradlew
publishDocs, which handles putting the documentation where Jenkins expects
for publishing.
