The wpimath APIs use std::array, which doesn't do size checking. Passing
an array with the wrong size can result in uninitialized elements
instead of a compilation error.
This is a breaking change but is worthwhile to avoid hard-to-debug errors.
This also shifts the trajectory up and to the right so that the robot is
always visible in the Field GUI during traversal. Some drive constants
and trajectory constraints were also synced between the two languages.
Flip the TeleopArcadeDrive axis directions so that positive
values for x-axis speed result in the Romi driving forward (in the
direction of the Raspberry Pi USB ports).
This makes code easier to read and more consistent between C++ and Java.
Also update clang-format settings to always add a line break (even if no braces are used).
Pose and state estimators can filter latency-compensated global measurements and fuse them with state-space drivetrain model information to estimate robot position. They are drop-in replacements for the existing odometry classes.

This fixes an issue with some commands not correctly requiring their
subsytems. Furthermore, an execute() method was added to the
DriveDistance command to continuously update the voltage command.
Some vestigial functions were never removed, and C++ single-jointed arm
sim was missing a flag for disabling gravity simulation. This is useful
for mechanisms like turrets.
Fixes#2738.
This includes physics simulation support for arms/elevator models, as well as differential drivetrains.
Swerve might be added at a later date.

It was added as part of Bryson's rule described in
https://file.tavsys.net/control/controls-engineering-in-frc.pdf. It
doesn't really simplify usage though, and the same thing can be
replicated by multiplying the elements of Q by rho manually. It's easier
to do it that way, it's how 3512 has been doing controller debugging for
a while, and it's probably what other teams will do as well instead of
using the "more structured" way.
Removing these unhelpful overloads also simplifies the LQR interface.
This avoids users having to call both IsOperatorControl() and IsEnabled() to figure out if their robot is
enabled and in the teleop state. The expression above involves calling two methods that each have their
own lock.
These new methods should only involve locking one mutex, since only one call is made to HAL_GetControlWord().
