Partially revert previous change: cancelling a single loop would often
advance the gcode stream to the next wait-for loop if executed at the
beginning of an SD print, implicitly turning off the flag again.
Cancel the loop directly in UnconditionalStop() which stops the command
queue as well in an atomic way, handling this correctly.
Remove most of the duplicated code inside temp_runaway_stop(),
making it identical to the other temperature handlers.
Move the lower-level functions required to stop the entirety of the
machine into UnconditionalStop(). Reuse this function inside
lcd_print_stop().
Set the LCD alert message before calling Stop(), as done in other safety
handlers, so that the error is visible while the printer is stopping.
This also avoids other temporary status messages to appear before
the real issue is shown and/or STEALING the first CRITICAL alert
level before we do.
Use the internal lcd_status_message_level for multiple severity levels
of alert messages.
This is needed to distinguish between non-critical alerts (such as FAN
ERROR) from critical ones (any heater issue). During a failure
scenario, a critical error MUST NOT be overridden by a lower-level one.
As such LCD_STATUS_CRITICAL is currently used for all heater-related
errors that result in a safety full-stop.
Make sure to call lcd_timeoutToStatus.start() when the SD card is inserted
into the printer after it was removed beforehand.

In PR #3093 the progmem array FW_VERSION_NR was introduced to store the
version components, however the code didn't read it properly using the
pgm_read_* functions, making version comparisons fail.
Fix the existing/unused is_provided_version_newer() and reuse it in
show_upgrade_dialog_if_version_newer().
Similarly also read/update correctly the version in the eeprom.
- Move D23 into it's own function inside Dcodes
- Correctly include a break in the switch statement
- Show the dumper status (enabled/disabled) after toggling
- Allow to generate an immediate dump via g-code using D23 E for
symmetry with D20 E
When building with GCC 4.9.2 (bundled with PF-build-env-1.0.6.*), -Os
and LTO enabled, PID_autotune gets automatically inlined into
process_commands().
Sadly, due to the massive size of process_commands(), it results in
codegen bug doing a partial stack overwrite in process_commands()
itself, manifesting as random behavior depending on the timing of
interrupts and the codepath taken inside the merged function.
Mark the function as noinline and add a note about the affected compiler
version in order to be checked again in the future.
Instead of using a mixture of int8_t, unsigned char and (incorrectly)
int, use uint8_t consistently for indexing the current block.
This improves the performance of the wait loop in plan_buffer_line,
which currently expands all comparisons to a word for no reason.
This also extends the theoretical limit to 128 entries.
Add some static assertions to ensure BLOCK_BUFFER_SIZE is correct.
This avoids the "busy" output interleaving with regular output in very
rare scenarios.
We should focus in finding which calls are not using manage_inactivity()
properly instead of working it around.
Code running in the temperature ISR needs to be fully reentrant, which
is hard to track down.
Move autoreporting to the main processing loop. This can make the
autoreporting slower or pause at times, but removes the reentrant
restriction, which allows us to use printf_P.
This PROGMEM is currently ignored by gcc, but even if it wasn't it
wouldn't be correct since the following code is expecting to read "item"
without fetching the array itself from PROGMEM.
