n_samples is an uint8_t .

at least the lcd independent part from Marlin_main.cpp.

to MELZI_MAKR3D.

Fix for #2288
As the normal MELZI also can have a 1284.

ZigZag has been disabled by fault due to do_topography_map

Also clean up some trailing spaces in a few other sources

- Add 3 new lines to `pins.h` to remove 2 redundant tests in
`pins_RAMPS_13.h`

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.

Fixes the problem of these pins being left in INPUT state, as described
in #1497

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.

Now send only temperature for T or B, but not send OK.
Host interprets the line to show the right temperature, but not in
response to M105 then stop and send commands until it ends the autotune.

by avoiding the strncopy()

The volumetric multiplier display needs to be multiplied by 100 in order to make it an integer for display purposes.

when DEFAULT_STEPPER_DEACTIVE_TIME is over
instead of simply turn off all.

it's disabled by default

Note that newer versions of the IDE can still
be made to support compilation for the older boards.

More general solution to skip N[0-9]+[ ]* in the parser as in #2218

- When editing on the LCD, minus now means below the nozzle
- Stores the opposite sign in EEPROM, so bumped to “V20”

#defining something just to define something else doesn’t
make sense

If you want SDCARDDETECTINVERTED, just define it yourself.

If the previous code was intended to define, undefined and then again define the term, that code is improper.
