Store the pressure_advance value in "struct extruder_stepper" instead
of in the trapq's "struct move". This makes it possible for multiple
stepper motors to have different pressure advance values while still
using the same trapq.

Using sc->last_step_clock for the last position marker does not work
properly, because the stepper.py code calls stepcompress_reset() prior
to calling stepcompress_set_last_position(). Fix by passing an
explicit clock to stepcompress_set_last_position().

Some internal code treats the message ids as encoded "variable length
quantities", while other internal code assumes the message id is
always one byte long. Continue using this scheme, but convert the VLQ
users to use the name "msgtag" while the 1-byte users use "msgid".
Increase the number of available msgids from 96 to 127 - the higher
values get encoded as negative "msgtags".

The default on X86 32bit machines is to use 80bit floating point math
(as found in the ancient "387 coprocessor"). This can cause numerical
stability problems. Set the compiler flags to make sure the newer SSE
math is always used on X86.

Input shaping can help to reduce printer vibrations due to resonances
and eliminate or reduce ghosting in prints.

Add ability for the host code to get a notification when the ack for a
command sent to the micro-controller is received. This is in
preparation for improved detection of message loss between mcu and
host.

Implement the pressure advance calculations while performing the
definitive integral calculations. This simplifies both the
extruder.py and kin_extruder.c code.

Support averaging the extruder position over a time range to "smooth
out" the velocity changes that occur during pressure advance.

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.

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.

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.

Now that all callers use the trapq system to queue moves, it is no

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.
