Kevin O'Connor 390d549c0c delta: Fix maximum halt velocity calculation
If an arm is nearly parallel to the bed then that tower's carriage may
have a velocity up to 3 times greater than the toolhead's maximum
velocity (relative to the print).  Take that into account when
calculating the stepper's maximum halt velocity.

This fixes some rare "No next step" shutdowns on delta printers.

Kevin O'Connor ca505bf4ac kinematics: Convert get_rails() method to get_steppers()
All callers of get_rails() actually just want the steppers, so return
them directly.

Kevin O'Connor a31c31aed4 mcu: Enhance itersolve stepper kinematics allocation
Allocate the stepper_kinematics directly in mcu.py - that way the
kinematic classes don't have to interact with the chelper code.

Kevin O'Connor b988596519 toolhead: Fill cmove in toolhead instead of in each kinematic class
This simplifies the kinematic classes.

Kevin O'Connor 8faab46ed2 toolhead: Move kinematic modules to new kinematics/ directory
Move extruder.py, cartesian.py, corexy.py, and delta.py to a new
kinematics/ sub-directory.  This is intended to make adding new
kinematics a little easier.
