Major staticification.
Make member functions static and instead utilize the Position system to
get a pointer to the class. This allows the compiler to figure out that
the class pointer is constant, even when functions are not inlined. It improves code size and speed.
Steppers: refactor to how it's done elsewhere now
Remove unused files in meta/ folder.
Remove one more unneeded file.
Position.h: make use of GetContainer instead of hardcoding this
Use baud 115200 by default.
It seems to be working reliably now.
