1e9c79c587 [sim] Use plant output to retrieve simulated position (#3043)
Using the plant output means that measurement noise can be incorporated.
SingleJointedArmSim (in C++ and Java) and ElevatorSim (in C++) used the
state instead of the measurement.

Closes #3042

62f0f8190d [wpimath] Deduplicate angle modulus functions (#2998)
frc::NormalizeAngle(), units::math::NormalizeAngle(), and
frc::GetModulusError() were replaced with frc::InputModulus() and
frc::AngleModulus().

They were placed in wpimath/src/main/native/include/frc/MathUtil.h for
C++ and wpimath/src/main/java/edu/wpi/first/wpiutil/math/MathUtil.java
for Java.

6e1919414e [build] Bring naming checkstyle rules up to date with Google Style guide (#1781)
Also update Checkstyle to 8.38.

Google changed their style guide from the last time we imported it. This PR brings in those naming changes. The change they made is allowing single letter member, parameter, and local variable names. They also added a lambda naming scheme and I thought it would be good to bring that in too.

10b396b4c2 [sim] Various WebSockets fixes and enhancements (#2952)
This is a breaking change to the WebSockets layer to align it with
recent specification documentation work.

To support this, HAL SimValue changed readonly to a direction enum.
This allows specifying bidirectional in addition to input and output.

The SimValue change is specifically designed to avoid API and ABI breakage.
This is completely transparent in C++; in Java a new callback class was added,
and the old readonly functions have been marked deprecated.

A new SimValue creation function for enums allows specifying double values
for each enum value, not just strings.  This allows mapping enum values to
doubles in the WebSockets layer.

A ":" in the SimDevice name now maps it to different WebSocket types (e.g.
"Accel:Name" becomes type "Accel", device "Name").  The type is hidden
in the GUI.

Other WebSockets changes:
* Implemented match_time and game_data
* Added joystick rumble data
* Added builtin accelerometer support
* SimValue enums are mapped to string and double value on WS interface
* Added WebSockets protocol specification
* Added READMEs

7c8f1cf7af [wpilib] Support scheduling functions more often than robot loop (#2766)
Currently, teams have to make a Notifier to run feedback controllers
more often than the TimedRobot loop period of 20ms (running TimedRobot
more often than this is not advised). This lets users add callbacks to
the main robot loop that run at a user-defined period. This allows
running feedback controllers more often, but does so synchronously with
TimedRobot so there aren't any thread safety issues.

8f3e5794b3 [wpilib] Add TimedRobot unit tests (#2771)
To make the tests reliable, the synchronization in simulation Notifiers
had to be reworked. StepTiming() now waits for all Notifiers to reach
HAL_WaitForNotifierAlarm(), then steps the time, then lets any expired
Notifiers run.

While there, we made some variable names more descriptive and added more
comments.

a112b5e231 [wpilib] Fix ProfiledPIDController continuous input (#2652)
There were three bugs:

1. The input range variables used in ProfiledPIDController::Calculate()
   weren't being updated
2. The modulus error calculation was incorrect.
3. The setpoint wasn't being wrapped like the goal, so the invariant
   that the error remains less than half the input range was violated.
   (Thanks to @CptJJ for pointing this out and suggesting a fix.)

c3b3fb8b74 [sim] Change StepTiming to wait for notifiers (#2603)
Old behavior is available via StepTimingAsync.

This makes it significantly easier to use simulation timing with notifiers.

Also update tests to use simulation framework.  This also speeds up the
timing-dependent tests by using simulation timing.  ResourceLock is used
in the Java tests to prevent parallel execution.

While we're here, tweak HAL Notifier implementation:
- Use wait_for instead of wait_until in WaitForNotifierAlarm
- Check for triggerTime = UINT64_MAX in UpdateNotifierAlarm
