Kevin O'Connor 6d0c55b6c1 extruder: Initial support for "smoothed pressure advance"
Support averaging the extruder position over a time range to "smooth
out" the velocity changes that occur during pressure advance.

Kevin O'Connor d39142139e stepper: Remove set_commanded_position() call
Now that the only caller to set_commanded_position() is
set_position(), remove the set_commanded_position() method and pass
the set_position() call directly to the itersolve.c code.

Kevin O'Connor 86121ff79e toolhead: Calculate and store axes_r in move class
Calculate the ratio of axis distance to total move distance (axis_d /
move_d) and store in a new member variable axes_r.  This avoids
needing to recalculate the value in other code.

Kevin O'Connor 076a66f791 trapq: Use separate 'move' entries for accel, cruise, and decel phases
Only track a single acceleration movement in a 'struct move' instance.
Break the classic trapezoid movement (accel, cruise, decel) into three
separate movements.  This simplifies the calculation logic.

Kevin O'Connor 1acaaa98c2 trapq: Remove move_fill()
Now that all callers use the trapq system to queue moves, it is no
longer necessary to individually allocate and fill a 'struct move'.

Kevin O'Connor d3afe4f1d8 trapq: Initial support for building a queue of trapezoidal velocity moves
Add support for building a list of moves in the trapq.c code.  Update
the toolhead code so that moves generated from the look-ahead code are
added to that list.

Kevin O'Connor 890298d34d itersolve: Support setting the stepper position via a cartesian coordinate
Add support for an itersolve_set_position() function that sets a
stepper position from a cartesian coordinate.  This eliminates the
need for both the python and C code to be able to translate from a
cartesian coordinate to a stepper position.

Kevin O'Connor d798fae20b serialqueue: Limit message transmission to available receive buffer size
If the mcu is using a traditional serial port, then only send a new
message block if there is space available in the mcu receive buffer.
This should make it significantly less likely that high load on the
mcu will result in retransmits.
