- Nonlinear auto bed leveling code (includes G29, G30, Z_RAISE_AFTER_PROBING). Cleaned it up to be a delta-specific AUTO_BED_LEVELING_GRID code path.
- Allen key z-probe deployment and retraction code. Cleaned it up and added safety checks.

- Also update base configs

- Moved sanity-checks to Marlin_main.cpp
- Applied to other configuration files
- Fixed formatting of ABL output
- Passing verbose level to probe_pt
- Miscellaneous cleanup
- Put CONFIG_STEPPERS_TOSHIBA into Configuration.h

This font is very special. It uses a mixture of katakana an kanji symbols, uses multi character symbols and is only addressable by '\xxx' sequences.

The former place of 'dogm_font_data_6x9_marlin.h' was in 'dogm_font_data_m0arlin.h'.

Deleted 'dogm_font_data_marlin.h'.

- A redo of #1576, which missed topo_flag
- Always set verbose_level

Fonts have been created with fony.exe (http://hukka.ncn.fi/?fony)

The HD44760_? fonts simulate the fonts of the character based displays.
The ISO10646 fonts provide the right size of the standard fonts.
Marlin_symbols contains only the the special symbols of the original marlin font.

add ```^ !(n_ENABLE_ON)``` for each stepper

  * "G1 X1 ; test" was not executing "G1 X1" due to never leaving comment mode.
  * "M117 Hello \;)" printed "Hello \" to the display due to not replacing serial_char properly.

Tested with the following commands:
    * M117 Hello ; test => displays "Hello" on display, ignores "test"
    * G1 X1 ; foo => moves 1mm in X, ignores "foo"
    * ; test => completely ignored, not even acknowledged
    * M117 Hello \;) => displays "Hello ;)" on display
    * M117 Hello \\;) => displays "Hello \" on display, ignores ")"

Autoretract was broken, looks like it was overlooked when the retracted flag was updated for multi extruders.

- Setting boundaries based on configured limits, contrasting with G28
(which forgets these limits?)

- Adapted “Enhanced G29” code referred to in #1499 and posted at
[3dprintboard.com](http://3dprintboard.com/showthread.php?3105-Auto_Bed_
Leveling-Enhanced-G29-command)
- Compatible with current G29 while adding some new arguments
  - `V` sets the verbose level for serial out
  - `T` (or `V` > 2) send a Topology report to serial out
  - `E` works the same way as before
  - `P` works as before (source used `n` or `U`/`u`)
  - `L`, `R`, `B`, `F` work as before
- Still needs sanity checking for `LRBF`

The X_Axis could not home to min while Y_Max endstop was trigged.

- Apply standards to cardreader.*
- Fix minor issues with cardreader.cpp
- Apply standards to some other stale regions

The encrot values are used in only one place, and don’t vary, so remove
redundant references.

This reverts commit fb75a9272d.

- Do field grouping
- Tweak configurations for better grouping

- Parse #if, #ifdef, etc. for rules to enable fields

- Both TMC, L6470 and pin-driven drivers work.
- All can be mixed and matched as needed.
