Commit 002dc0df added rounding to the homing speed, but it did not
work if the configured homing speed was less than the printer's
maximum velocity. Move the speed rounding from stepper.py to
homing.py and make sure the rounded speed is less than the maximum
speed.

Add the ability to alias multiple output pins from a single pin alias.
This makes it possible to support some cases where a single logical
output is driven by multiple output pins.

Add initial support for extracting out shutdown information from a
klippy.log file. The shutdown dump will be reordered into the
sequence that they occurred, and timestamps/sequence numbers in the
mcu message dump will be expanded.

The atmega168 and atmega328 need to define PE0 and PE1 in order to
support the 2 extra analog pins.
Also, support the arduino mappings for the atmega328.

Change the config file so that the delta arm length is specified
per-tower. This makes it possible to support advanced calibration.

Use the formulas for trilateration (instead of the circumcenter
formulas) when calculating the position of the nozzle from the
position of the carriages. The trilateration formula is more general
and it allows each tower to have a different arm length.

It's valid to consider the stepper at a position that is not on a step
interval - only the "mcu position" needs to be an integer.

Add a new config option 'homing_endstop_align_zero' to enable the
alignment of the endstop to a stepper full step. It's possible one
may wish to specify a homing_endstop_phase while not aligning the
endstop.

Move the homing logic out of toolhead.py and into homing.py. This
simplifies the toolhead logic and centralizes the homing code.

Reset the last step clock during the init phase and after each home -

Make sure to always call MCU_endstop.home_wait() if
MCU_endstop.home_start() is invoked. Rename
MCU_stepper.note_homing_triggered() to note_homing_end() and make sure
it is always called if MCU_stepper.note_homing_start() is invoked.
With these changes, MCU_endstop.home_finalize() is no longer needed.

The homing code wants the list of endstops to enable during a homing

Commit e05c6354 changed the internal step compress queue from 64bit
integers to 32bit integers. However, that commit broke the proactive
flushing of moves that could produce more than 64K steps. This could
lead to large memory allocations and cpu slow downs on printers that
had a very large Z axis - possibly leading to a "Timer too close" mcu
shutdown. Correct the code so that it properly generates a 64bit
flush clock.
Also, be sure to only expand / memmove the queue when there is no room
for a new element at the end.

Instead of adding 250ms to each homing operation add a time relative
to the number of estimated steps that are to be generated. This
scales the delay to really large axes without adding a delay for
normal users.
