Kevin O'Connor 04b3603a1e itersolve: Rename scan_pre/_post to gen_steps_pre/post_active 
Rename the variables to make it a little more clear what they do.

Kevin O'Connor 080ee0b512 kin_extruder: Apply pressure advance in kin_extruder.c 
Implement the pressure advance calculations while performing the
definitive integral calculations.  This simplifies both the
extruder.py and kin_extruder.c code.

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 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'.
