More functionality was implemented at the HAL level, so expose that to the wpilib level.
This also does units changes for all the PH related functionality.
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.
UpdateEntries() and Flush() are called from methods that lock the mutex,
so locking it again will cause deadlocks. This also updates the Java
code to make MechanismObject2d::update synchronized like in the C++
version.
As the sensor needs to maintain an actual duty cycle, it can't go all
the way from 0-100, so provide a way to set the min and max and linearly
map between the two.
The root cause of #3747 is CommandScheduler's ds state checks are behind iterative robots checks. This means that the iterative robot state could return enabled, but the DS cache could still be reporting disabled. This results in a race in the Disabled -> Enabled transition, which manifests in commands not running.
Previously, iterative robot base pulled from the DS cache. This meant that the ds cache was always updated before an iterative robot base loop could run. This still had a race, but this could only occur on the Enabled -> Disable transition, which is much less noticeable and would usually just result in a command running for an extra loop.
We can move back to the old behavior by grabbing the new iterative robot base check variables to use the DS cache.
If something happens with the PD connection, these would have spammed messages continuously.
This wasn't the case previously, and we don't want this behavior now.
Timer reports a negative duration if the sim timing is restarted. This
can be worked around by calling Reset(). Other options included:
1. Have RestartTiming() call Timer::Reset() on a list of instantiated
Timers.
2. Have Timer::Get() reset the timer if it notices time went backwards.
This requires dropping const qualification though, which is a
breaking change that only fixes a minor edge case.
Closes#2732.
Supersedes #2358 with updates and cleanups.
Closes#2482 and closes#2487 because we shouldn't support both
time-based and count-based debouncing approaches.

Having PCM as a singleton is a problem, as multiple things need to use it, and that gets really ugly. This changes PCM's to be a reference counted object, that can be passed around and constructed from multiple places.
In Java, this is using a map to hold a data store with a ref count, and allocating new objects any time a duplicate is requested.
In C++, this uses a trick constructor to store a PCM instance in the data store itself. This instance can then be passed to base objects using std::shared_ptr's aliasing constructor, which means constructing a solenoid from a PCM is not allocating after the 1st one.
This did require removing sendable from PCM. A compressor class was added back in to act as sendable for the PCM.
After this change is finished, the only change RobotBuilder and Team Code would require is passing a module type to solenoid constructors.

The standard Java package is missing BooleanConsumer as well as Float classes.
Update SendableBuilder to use it instead of internal BooleanConsumer
interface.
In some cases, knowing roborio 2 might be useful. This also creates a higher level enum that might be usable later for the discussion on more complex runtime types.
This PR gives the Notifier HAL thread RT priority 40 in RobotBase after
HAL initialization and before the user code is run. This drastically
improves scheduling jitter for TimedRobot's AddPeriodic() functions (in
3512's experience).
It's too risky to set user code as RT because badly behaved code
will lock up the Rio (potentially requiring safe mode to recover).
This needs the user program to be setuid admin to succeed.
- GenericHID is now concrete, and has only getRawAxis/Button(int) functionality
- getXxx() has been moved into Joystick as that's the only place where it makes sense
- Hand (and therefore getXxx(Hand)) has been removed, replaced by specific getLeft/RightXxx() methods in XboxController and the new PS4Controller class
- C++ ::Button:: and ::Axis:: enums have been converted to identically-namespaced static constexpr ints
They don't provide much utility for the end user. A print at the call to
HAL_ObserveUserProgramStarting() was added in their place so it's still
clear when constructors have finished running.
