2919f37343 stepcompress: Store a reference to 'struct stepper_kinematics'
Support storing a reference to 'struct stepper_kinematics' in 'struct
stepcompress' and support globally generating steps via the
steppersync mechanism.

447125faae serialqueue: Eventually time out if unable to write CANbus messages
Klipper logs an error on a failed CANbus write.  Unfortunately, if the
bus becomes permanently disabled (eg, due to a user removing power to
devices on the CANbus) then it can result in the logs filling with
error messages.

Permanently disable the low-level processing of messages if CANbus
writes continually fail for at least 10 seconds.  This avoids filling
the log with redundant messages.

22ee889f41 serialqueue: Rename stalled_bytes stat to upcoming_bytes
The stalled_bytes counter refers to the number of bytes that are not
yet eligible for transmission.  However, the naming leads to confusion
as it could be interpretted as an inability to transmit data.  Rename
to upcoming_bytes to try to avoid that confusion.

b17ec3d2e9 stepcompress: Pass clock to stepcompress_set_last_position()
Using sc->last_step_clock for the last position marker does not work

to calling stepcompress_set_last_position().  Fix by passing an
explicit clock to stepcompress_set_last_position().

f8b0ea53dc serialqueue: correctly report EOF errors
If `klippy` loses connection to a device, the next `read()` from the
device file descriptor will result in a zero-byte result, i.e. an `EOF`.
Right now this gives a confusing error message, so this simply handles
the special case of `EOF` and outputs a better log message.
