Also fix the return type of HAL_IsNewControlData() and HAL_MatchType's type.
Since UsageReporting is intended to be namespaced, it is hidden when this is being used in C.

The models and meshes are not included. We will need
to find an alternate way to reintegrate these and use them.
* Add simulation/gz_msgs back, and build with Gradle.
* Add back in the frc simulation plugins for gazebo.
* Add a new shared library, halsim_gazebo.
This library will become the interface between the
HAL sim layer and gazebo.
* Preserve the first channel number used in created Encoders in the Sim MockData.
This allows us to use the DIO channel number to connect with simulated encoders.
* Have the HAL Simulator set the reverse direction on creation.
This enables a simulator to be aware of the direction.
* Add a drive_motor plugin.
This is a bit of a 'magic' motor, which allows us to build robot
models that drive in a more realistic fashion. It does this
by apply forces directly to the chassis, rather than relying on
the complex motion dynamics of a driven wheel.
This in turn allows the model to reduce wheel friction,
reducing scrub, and allowing for a more natural driving experience.
Making Travis run wpilibj_frcnetcomm.py will help avoid bitrot in
FRCNetComm.java in the future. Formatting was also enabled on Python
source files and FRCNetComm.java was added back to the generated files
list.
During shared library loading, a different libLLVM can be pulled in, causing
llvm symbols from dependent libraries to resolve to that library instead of
this one. This has been seen in the wild with the Mesa OpenGL implementation
in JavaFX applications (see wpilibsuite/shuffleboard#361).
This is clearly a very breaking change. For some level of backwards
compatibility, a namespace alias from llvm to wpi is performed in the "llvm"
headers. Unfortunately, forward declarations of llvm classes will still break,
but compilers seem to generate clear error messages in those cases
("namespace alias 'llvm' not allowed here, assuming 'wpi'").
This change also moves all the wpiutil headers to a single "wpi" subdirectory
from the previously split "llvm", "support", "tcpsockets", and "udpsockets".
Shim headers will be added for backwards compatibility in a later commit.
