Use macros that explicitly avoid double-evaluation and can be used for any datatype, replacing `min`, `max`, `abs`, `fabs`, `labs`, and `FABS`.

- This status screen uses the ST7920 character generator to greatly
reduce SPI traffic and MCU load when updating the status screen.
- Has been tested with the RepRapDiscount Full Graphics Smart Controller
but should work with any LCD that uses an ST7920 or fully compatible
controller.
* VIKI2 & RE_ARM changes
1. Remove `DISABLED(SDSUPPORT)` from ST7565 in `ultralcd_impl_DOGM.h`. These LCDs share pins with the SD card and can run at the SD card rates.
2. Add SDSS definition to `pins_RAMPS_RE_ARM.h`. Apparently the SDSS definition in `pins.h` is being processed before the one in `spi_pins.h` which resulted in not being able to read the SD card.
* Fixing the DUE serial port assignments: Now -1 means the SAM3x USB Device emulating a serial port, and 0 means the USB to serial adapter included as a programming port
* Improving the Fast IO port access implementation on Arduino DUE
* Implemented EEPROM emulation on Due by storing data on the internal FLASH (with wear leveling)
* Implemented a Software SPI for the ST7920 graphics display for the Arduino RAMPS for DUE, as the default one in u8glib is clocking data too fast on ARM, and the display does not understand it.
* Fixing the case where the serial port selected is the USB device
* Adding configuration for the Makerparts 3D printer (www.makerparts.net)
* Tuned MakerParts acceleration on X and Y axis so it never loses steps. Also adjusted pulses per mm to match default hw configuration
* Fine tuned Maximum acceleration for MakerParts printer
* Style cleanup
* Style cleanup (2)
* Style fixes (3)

* Style changes to u8g_dev_st7920_128_64_sw_spi.cpp
* Even more improvements to the FastIO HAL for DUE. Now WRITE() is 2 ASM instructions, if value is constant, and 5 cycles if value is not constant. Previously, it was 7..8 cycles
* After some problems and debugging, seems we need to align the interrupt vector table to 256 bytes, otherwise, the program sometimes stops working
* Moved comments out of macro, otherwise, token pasting does not properly work sometimes
* Improved Software SPI implementation on DUE: Now it honors the selected speed passed to spiInit(). This allows much faster SDCARD access, improving SDCARD menus and reducing latency
* Update u8g_dev_st7920_128_64_sw_spi.cpp
* Disabling EEPROM over FLASH emulatiion if an I2C or SPI EEPROM is present
LPC1768 VIKI2 & RRDFG are working
looks like all SPIs are working
library change
sh1106 locks up
fixed lockup, started I2C SW com
pretty
re-org
restore a few files
make library happy
switched HAL version of rrd
fix travis error
travis error fixes
another travis fix
cleanup
minor update
one more
correct spacing in platformio.ini
