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

Writing to the debug log can cause an unbounded delay due to disk IO.
This is particularly so on embedded machines such as the Raspberry Pi
that run on SD cards. These log writing delays can cause problems for
the main processing threads.
The new "queuelogger" code forwards all the main thread log messages
to a queue, and a background thread writes the log messages from the
queue to the destination file. This eliminates the IO delay from the
main threads.

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.

Some details on the code flow and organization have changed since
support for ARM processors was added. Update Code_Overview.md
accordingly.
