Thomas Clark 8abbcf53f4 Update to the v13 headers and libraries
Add all of the most recent headers and .SOs

Also make DriverStation work with the new FRC comm protocol, using the new
functions for getting status data

Change-Id: I1c7fc5f90e72c5fbebf87d9923ce0967ed0ef3bc

Initial HAL support for v13 ds

Change-Id: I9a7f37ef8e24241598fa3981cb3df30c07c52e0f

New ds stuff in the HAL

Change-Id: I025910625453baf63f79f49bbc70ba8b2f093f50

New ds stuff in C++

Joysticks are still todo

Driver station IO is pulled out

Change-Id: I1bb59037c097713bd943e7bef00e12f67f13c3ac

New ds works in C++ and Java.  Joysticks still todo

Change-Id: Ic93f8686856761badc592eceaf05964f52355578

Make joysticks work again with the v13 image protocol
