Instead of checking for explicit versions, resume the wizard if some
(new) wizard is missing.
This handles both the old SELFTEST check, the new thermal model
and any future check in the same fashion.
- Move calibration status/declarations to util.h
- Allows to query the status of each step independently without assuming
any order
- Allows to extend the calibration with new steps transparently
- Generalize force_selftest_if_fw_version() so we can check when upgrading
between arbitrary FW versions.
- Do not call update_current_firmware_version_to_eeprom() prematurely
when forcing self-test (if a reset happens before self-test completes,
the check would be incorrectly skipped on the next run).
printer_smodel_check was incorrectly substituting the final " with a
null in the command to simplify the model string comparison, but in
doing so was also corrupting the next pop from the cmdqueue.
We can modify the current strchr_pointer as long as we *don't* change
it's length. This can cause an incorrect extra read from the queue,
resulting in the last command to be completely ignored.
