MCP4728 consistency & fix ultralcd.cpp

The MCP4728 DAC controls the stepper motor current strenth on the
PRINTRBOARD Rev F and RIGIDBOARD V2 boards.

PR #5792 on 9 FEB 2017 implemented default drive percentages but only on
the RIGIDBOARD V2.

This change moves the default settings to Configuration_adv.h.

Also, ultralcd.cpp won't compile because of a type def conflict.
Changed it to match the one in stepper_dac.cpp

===========================================================

reword stepper curent section for clarity

===========================================================

change name & improve comments

===========================================================

changed name from A4JP to SCOOVO_X9H per PR #6139

# This is the commit message #2:

fix typo

M43 - add Toggle utility and Z servo utility (replaces PR #5864)

Z_DUAL_ENDSTOPS -  make offset a configuration item

The offset for Z_DUAL_ENDSTOP (z_endstop_adj) is already in Marlin.
This PR just makes it a configuration item.

z_endstop_adj is initialized in two places so both had to be modified.

pinsDebug with more features, uses less RAM

I've just uploaded a major change to pinsDebug.
The big change was creating an array in FLASH that contained every
active pin definition. That reduced the RAM memory usage considerably
but increased the FLASH usage.
Creating the array requires going through the pin list twice. Rather
than having two copies of it in the code I moved the list out to another
file (pinsDebug_list.h) and then just did two #includes.
From the user’s view they’ll see the following changes:
1. Now reports all the names assigned to a pin
2. The port is now reported in addition to the pin number.
3. When PWM0A & PWM1C share a pin, both PWMs are reported
4. More PWM/Timer info is reported
One new item that may cause some concern is the usage of the LINE
predefined preprocessor macro. It may not be available if the Arduino
IDE goes to a different compiler.

Includes support for 1284 & 1286 families.

Memory usage changes when enabling PINS_DEBUGGING:

==================================================================

minor changes - mostly formatting

1) added newline to end of teensyduino file

2) changed flag name from TEENSYDUINO to TEENSYDUINO_IDE.  Got warnings
about redefining TEENSYDUINO

3) removed some trailing spaces

reduce PROGMEM size & update pin list

Reduced PROGMEM usage by
1) converting often used macro to a function
2) moved as much as possible into the function

This required creating two arrays of address pointers for the PWM
registers.

==================================================================

update with new M3, M4, M5 pin names

report I/O status for unused/unknown pins

Group all UBL files via a common prefix

Use same config name for all mesh dimensions

Add hidden option to output Bilinear grids in JSON

Since run_probe was altered to return the probe Z position rather than the nozzle Z position bilinear levelling has been broken because the Z-offset has been applied twice - once in the run_probe function, and then again in the G29 code for bilinear levelling.

M421 was not connected up for AUTO_BED_LEVELING_BILINEAR.
M421 needed to migrate mesh data to new UBL EEPROM layout.

Power Supply 0 as "General"

As it turns out...   an unsigned int can not go to less than 0,  so the
loop never terminates.
