at least the lcd independent part from Marlin_main.cpp.

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.

- Also move audio feedback into the command
- Added shorthand for `lcd_buzz` availability

- Address issue raised in #1961

for when no LCD is defined.
Fix for #1770.

- Some messages should not expire with `PROGRESS_MSG_EXPIRE`.
- Simplify conditional for progress bar with sanity checks.
- Rename `messageTick` to `expireStatusMillis` and make it the expire
time.

to avoid warnings about unused blink.

Concentrate definitions of variables in dogm_lcd_implementation.h to one place.

Make only local used variable currentfont static.

- Add BIT and TEST macros
- Add _APPLY_ macros to stepper.cpp to help with consolidation
- Consolidate code in stepper.cpp using macros
- Apply standards in stepper.cpp
- Use >= 0 instead of > -1 as a better semantic
- Replace DUAL_Y_CARRIAGE with Y_DUAL_STEPPER_DRIVERS

Introduced lcd_strlen() and lcd_strlen_P().
Replaced the old functions where necessary.
Reworked language_ru.h.

Speeded up test for zero length string in cardreader.cpp

Small changes (and formatting to confuse the diff’er) which first
allows DOGLCD and LCD_PROGRESS_BAR to be enabled in tandem, then a
#warning (rather than error) that the extra progress bar / message
options don’t apply to graphical displays at this time. This leaves
open perhaps combining the progress bar and message area in some future
(or forked custom) graphical LCD display arrangement (at which time the
relevant variables may be moved into ultralcd.cpp with externs in
ultralcd.h). I also added a conditional error that the progress bar and
the filament display may not work well together.

sp=space-padded, similar to: ns=no-sign

Allow M0 and M1 to include a message string. Ignore clicks on “Wait for
user” so that the Info Screen stays up.

Changes to support displaying the real-time filament width and the
volume factor on a 20x4 LCD.  The data is displayed on the 4th line.
First the status message is displayed for 5 seconds, and then the
filament data is displayed.  The status message can be seen by
re-selecting the info screen in the menu.

Diffed and merged, preserving my updates

- changed the variables from keypad to reprapworld_keypad
- added a missing ifdef check

Argument order of lcd_buzz was set to mirror that on tone(). Change
default M300 frequency to something audible.

A new variable was introduced to allow fan animation on the GLCD.
Add additional float to string conversion routine without sign
character. This is used for the coordinates visualisation on the GLCD.

This includes refactoring the buttons code to remove a large amount of
non-pin dependent duplication from pins.h.

The cli(); at the start of the kill() function also stops the internal
arduino timer which stops updating of millis() which prevents the
display of the "KILLED." message.
The new function updates the display directly without checking any
timers.
