The changes made in this commit do not affect any actual code,
they are purely aesthetic. I ran clang-format with google style
over all .h/.cpp files in wpilibc that weren't in wpilibC++Sim
or gtest, and the eclipse formatter over all of the Java files
using the Google eclipse formatting configuration.
