When a delta printer has different arm lengths or different endstop
positions then the homing position falls outside of the normal
printable area. Add a special check to the range checking code to
permit this move instead of homing to a position near the actual
homing position.

Move the logic for performing the second home from the kinematics
classes to the generic homing code.

Commit b0d859f2 introduced a second_homing_speed parameter, and it
also changed the retract speed. Revert the retract speed change (use
homing_speed when the head retracts).

Move the "stable position" logic from the delta.py kinematics code to
the delta_calibrate.py calibration code.

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.

Allocate the stepper_kinematics directly in mcu.py - that way the
kinematic classes don't have to interact with the chelper code.

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.
