Using GetAverageVoltage will reduce the noise in potentiometer reading. Potentiometers are unlikely to be used where the minimal lag averaging introduces would impact control loop stability.
This makes it much more user-friendly to use simulation classes without needing
to ifdef for C++ to avoid linker errors or be very careful about construction
to avoid runtime errors in Java.
This is a derived class of HttpServerConnection that implements the
WebSocket upgrade pieces. This combination is pretty common so is
worth refactoring here.
When not direct mapped, make index constructors private and add factory
functions for channel and index.

This allows disabling/enabling SimDevices via prefix matching. This can be
used to force devices that normally use SimDevice in simulation mode to
instead talk directly to the hardware as in normal operation.
pose.Translation().X() and pose.Translation.Y() are common operations,
so shortening them to pose.X() and pose.Y() would be convenient.
Java uses the getX() convention so that is used instead of X() for Java.
We already have predefined linear acceleration units and angular
velocity units. This makes defining acceleration constraints for angular
trapezoid profiles more convenient.
No tests were added for this because the base unit conversions are
already tested. Angular acceleration just adds another time dimension.
With the new extraction method, we would need to provide an opencv. However, all of our tools that use opencv use an alternate version of OpenCV, so that would interfere.
This adds an artifact where opencv is statically linked into cscore, but wpiutil is a shared dependency. This solves some shared state hacks, and the extraction works so much better, so its worth making this change to allow that
Also move some things in HAL for consistency.

* Add new combined native class loader
Allows us to extract a list of binaries that depend on each other, and load them successfully
It is correct that there is no implementation in wpiutil for the new native method. That is a requirement, because its needed to load the libraries, and we cant load the wpiutiljni native library since it depends on wpiutil. Instead we have a separate library built with the tools plugin that handles everything
Previously this would list ALL /dev/video* devices. In recent versions of
Linux this leads to listing duplicate devices, as many USB cameras provide
both a video device and a metadata device, and only the video device can
actually be used for streaming.
