3f77725cd3 Remove uses of iostream (#4004)
Most of these were unused, the IMU ones were just debug messages.

The only one that wasn't removed is in portable-file-dialogs.cpp since
the replacement looks less trivial.

db0fbb6448 [wpimath] Fix LQR matrix constructor overload for Q, R, and N (#3884)
It was using the continuous B matrix to compute the feedback gain
instead of the discrete B matrix.

Tests were added for the matrix constructor overloads.

7269a170fb Upgrade maven deps to latest versions and fix new linter errors (#3772)
This also makes the Gradle build work with JDK 17.

The extra JVM args in gradle.properties works around a bug with spotless
and JDK 17: https://github.com/diffplug/spotless/issues/834

PMD.CloseResource was ignored because it's almost always a false
positive, and there are many of them.

d6f185d8e5 Rename tests for consistency (#3592)
I started with the output of styleguide#217, then renamed a few classes
to fix compilation.

ntcore's StorageTest needed some manual renaming since it put the Test
word in the middle instead of at the end.

One limitation of wpiformat is test cases that were only named "Test"
were unmodified, and an error was generated. These test cases were
manually given more descriptive names:

* TimedRobotTest mode test cases had "Mode" appended to the name. Java
  tests were renamed to match.
* UvAsyncTest and UvAsyncFunctionTest cases were given alternate names

fe59e4b9fe Make C++ test names more consistent (#3586)
Inconsistent names were found using the following regular expressions.

* `rg "TEST(_F|_P)?\(\w+,\s+\w+Test\)"`
* `rg "TEST(_F|_P)?\(\w+,\s+Test\w+\)"`
* `rg "TEST(_F|_P)?\(\w+Tests,\s+\w+\)"`

Fixes #3495.

9359431bad [wpimath] Clean up Eigen usage
* Replace Matrix<> with Vector<> where vectors are explicitly intended.
  I found these via `rg "Eigen::Matrix<double, \w+, 1>"`.
* Pass all Eigen matrices by const reference. I found these via `rg
  "\(Eigen"` on main (the initializer list constructors make more false
  positives).
* Replace MakeMatrix() and operator<< usage with initializer list
  constructors. I found these via `rg MakeMatrix` and `rg "<<"`
  respectively.
* Deprecate MakeMatrix()

3b5d0d141a [wpimath] Add LinearFilter::BackwardFiniteDifference() (#3528)
This is an alternative to #2344 that handles arbitrary order derivatives
of arbitrary precision. The downside is that since it's part of
LinearFilter, it can't utilize the units type system in the same way to
make Calculate()'s input type different from its output type.

  * Required adding Runge-Kutta time-varying impl to tests
* Move C++ Runge-Kutta time-varying impl to tests only
  * Users don't need it

c1e128bd5a Disable frivolous PMD warnings and enable PMD in ntcore (#3419)
Some valid warnings like throwing NullPointerException or using a for
loop instead of System.arraycopy() were fixed.

Abstract classes marked with PMD.AbstractClassWithoutAbstractMethod were
made concrete because they already had protected constructors.

Fixes #1697.
