62731bea20 [wpilib] Add set functions to differential drive simulation (#2746)
All the other simulation objects already have functions like this
through LinearSystemSim.

651319589c [wpilibc] Fix a use-after-free in DifferentialDrivetrainSim (#2741)
In the second constructor, a new LinearSystem is created and set to
m_plant. This takes a const ref though, so it's storing a reference to a
temporary object. After the constructor finishes, m_plant points to an
invalid object. When Update() is called, it will crash with a
segmentation fault.

This patch fixes the use-after-free by making m_plant a LinearSystem
value type. The first constructor will generate a copy, but that only
happens once.

b61f08d3fa [wpilib] Add physics simulation support with state-space (#2615)
This includes physics simulation support for arms/elevator models, as well as differential drivetrains.

Swerve might be added at a later date.
