Expected behavior: After editing a value the menu should return to the
previous place with the edited item selected.
Actual behavior: Either the top (back) item from the previous screen is
selected, or the menu jumps up another level.
Solution: Pass the correct arguments to `lcd_goto_menu` on click when
editing a value.

Apply `constrain`, `NOMORE`, `NOLESS` and `CRITICAL_SECTION` macros
wherever possible.

Fix crashes when the Z axis is moved via LCD
by calling `plan_buffer_line` only when there is enough room in the
planner buffer, to avoid endless recursion.
A brief description about what went wrong is in #1166

For some reason that I cannot determine, using a sub-function causes
the Tune sub-menu to act strangely, yet replacing the function call
with its code content works perfectly.

by alternate definition for the callback macros

Move slow_buttons_update into the LCD_UPDATE_INTERVAL block
lcd_implementation_read_slow_buttons() will then be executed ~10 times a
second.

Restore the Babystep Multiplicator functionality and now it's available
for X/Y/Z

According to #123 negative values for XY at or below -100 are displaying incorrectly, dropping the first digit. Deltas can easily have XY values in this range. This PR adds a function to display floats/ints formatted like `_123`, `-123`, `_-12`, or `__-1` as appropriate and applies it to the XY coordinates on Hitachi displays. It also moves the Z value to the right to be consistent with the XY formatting.

Keep "astyled" reformatting

- `SD_DETECT_PIN` replaces `SDCARDDETECT`
- `SD_DETECT_INVERTED` replaces `SDCARDDETECTINVERTED`
- Revise the description of `SD_DETECT_INVERTED`
- Add a note about the override of `SD_DETECT_INVERTED` in
`Conditionals.h`

- Rename the pin so it can be tested with `PIN_EXISTS`
- Fix some incorrect tests for `SDCARDDETECT`

For consistency with other pins, allowing use of `PIN_EXISTS` macro.

Apply `ENABLED` / `DISABLED` macros to LCD-related files.

The compiler may be able to optimize if it knows an array won’t be
changing.

at least the lcd independent part from Marlin_main.cpp.

Also clean up some trailing spaces in a few other sources

by:
Moving HAS_LCD_BUZZ macro to Coditionals.h
Renaming HAS_LCD_BUZZ to HAS_BUZZER to make clear is has nothing to do with the lcd.
Removing the ULTRALCD condition.

Moving declaration of lcd_buzz() out of the ULTRA_LCD block in ultralcd.h
Moving definition of lcd_buzz() out of the ULTIPANEL block in ultralcd.cpp
Renaming lcd_buzz() to buzz() to make clear is has nothing to do with the lcd.

All buzzing code is now only dependent on the existence of a BEEPER-pin or the definition of a LCD_USE_I2C_BUZZER.

To do: Check the conditions for the BEEPER-pin in all pin-files.

Suggest we use the translated strings here. They use (except for
German) the phrasing “Move X” instead of just the axis letter, but they
should fit the available space. The “Extruder” string would be the
same, except it will be translated.

replace extruder_multiply with extruder_multiplier

I prefer to read N for Number not for Nozzle.

Make setTargetBed() in _lcd_preheat() dependant of TEMP_SENSOR_BED.
Use disable_all_heaters() in lcd_cooldown() and abort_on_endstop_hit.

Fixed a couple defines that were not changed or commented out.

Moved SDCARDDETECTINVERTED and SDSLOW to Conditionals.h.
Added U8GLIB_LM6059_AF to define display specific actions.
Added reminder to compile in u8glib
