The functions in Threads.h are in the frc namespace. `using namespace frc;` in
Threads.cpp doesn't put their implementations in the frc namespace, so linker
errors occur when attempting to use them in robot programs.
To fix this, one can either wrap them in a namespace block or prepend
`frc::` to the implementation's signature. Based on past discussion, I
opted for the namespace block.
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
