It's common for multiple steppers to use the same stepper enable
line. Detect this and only create a single digital_out oid on the
micro-controller.
Also, prohibit any other pin from being used multiple times in the
config file.

Several items were recently implemented. Remove the "cubic vs
quadratic" item as investigations into cubic compression weren't
promising.

It should no longer be necessary to configure "custom" commands during
mcu setup. The ad5206 and static_digital_output config sections
should provide similar functionality.

The term "firmware" is ambiguous - it could refer to the entire
project (host and micro-controller software) or to just the
micro-controller software. Avoid the term in the documentation.

The Klipper software has progressed to the point where it does not
need to be described as "experimental" software.

Add initial support for micro-controller resets via the Arduino reset
mechanism. Also, automatically attempt a firmware restart if the
printer CRC does not match.

Support human readable commands (eg, "help"). Add a "help" command to
list these extended commands.
Also, add support for declaring command aliases, command help, and
command availability next to the handlers themselves.

Check that all options specified in the config file are valid. This
catches possible typos and spelling errors in variable names that have
a default.

Instead of writing error messages to stderr, route them into the
python code and use the standard python logging system.

Should a homing move complete without hitting the endstop, then
disable motors, disable the endstop checking, and report the error to
the user.

Due to the lookahead, small changes in the direction of the toolhead
cause minor changes in toolhead velocity. These "cornering" velocity
changes cause the current extruder code to trigger pressure advance
and its associated pressure retract. This causes the extruder to
rapidly "jerk" the filament.
This code change updates the extruder to detect velocity changes due
solely to cornering and avoid pressure advance.
