Update to the 2019 wpilib

Lots of gratuitious incompatibilities to deal with. Started sanifying a
few classes rather than figuring out how to update them too. Has not yet
been tested on a robot, but everything still builds so it should be
fine.

Also ported over our FPGA timestamp fixes, which were previously only in
allwpilib_2018.

Also upgraded to the new roborio compiler, which has to happen at the
same time due to incompatible pre-compiled libraries.
