Enable the endstop interrupts feature for LPC176x boards. Although Smoothieboard chose to use non-interrupt capable pins for their endstops, and this has been copied by clones, so they can't use it.
* Misc fixes and improvements
- Get rid of most critical sections on the Serial port drivers for AVR and DUE. Proper usage of FIFOs should allow interrupts to stay enabled without harm to queuing and dequeuing.
Also, with 8-bit indices (for AVR) and up to 32-bit indices (for ARM), there is no need to protect reads and writes to those indices.
- Simplify the XON/XOFF logic quite a bit. Much cleaner now (both for AVR and ARM)
- Prevent a race condition (edge case) that could happen when estimating the proper value for the stepper timer (by reading it) and writing the calculated value for the time to the next ISR by disabling interrupts in those critical and small sections of the code - The problem could lead to lost steps.
- Fix dual endstops not properly homing bug (maybe).
* Set position immediately when possible
Use macros that explicitly avoid double-evaluation and can be used for any datatype, replacing `min`, `max`, `abs`, `fabs`, `labs`, and `FABS`.

Also simplify logic on all ARM-based interrupts. Now, it is REQUIRED to properly configure interrupt priority. USART should have highest priority, followed by Stepper, and then all others.

All HAL's read_data() and write_data() return false if they succeed.
* Get read_data() and write_data() return codes to be consistent
Make read_data() and write_data() return true if an error happens.
* Say UBL is now checked out on machine types in default Configuration.h file.

As requested :)
* Delete Configuration_adv.h
* Delete Configuration.h
* Deleted /Marlin/Marlin/src/config/examples/MksSbase/*.* and moved them to /Marlin/Marlin/src/config/examples/Mks/Sbase/*.*

This change initialize any data in eeprom.dat beyond the current file size to FF.
That way if eeprom.dat is deleted and created again, it doesn't take the old values or random ones, but rather starts with FF in all positions as a real brand new or erased eeprom.dat
Currently if you delete eeprom.dat and restart the board, the new file is created in the same sector with the same content, since FAT does not actually delete the data, just marks the sector as free. I tested by deleting the file, and then rebooting the board, and checking the file content.
The change can be tested in the same way, deleting, rebooting the board, and then the new content should be all FF.
If an eeprom file already exist with data on it, but smaller than E2END, it will be padded with FF on first access, so it will not have random or old content appended.
* fixed some include paths
* LPC1768: Fix Serial API
Add missing serial methods used if TX_BUFFER_SIZE is set
Change return value of HalSerial:read to match Arduino API
* LPC1768: add filters to ADC
This is to try and compensate for hardware issue and oversensitivity to noise
* LPC1768: remove the polling section of delayMicroseconds
* LPC1768: lock usb mass storage device while device accesses it.
Currently only applicable to persistent store,
The device always has priority and will unmount the sd card from the host, Windows then tries to automount again so it can look like the explorer window freezes. Linux Mint, by default, just closes the Nemo window.
* Add timeout to make sure if Serial never connects that Marlin still boots
* Remove unneeded ifdef CPU_32_BIT
In general the need for ifdef CPU_32_BIT blocks means that something is missing from the HAL API or a Platform, in this case HAL_TICKS_PER_US was missing from the AVR Platform
* LPC1768: relocate RE-ARM debug_extra_script.py
HardwareSerial has been tested on Uart0 (debug header) and Uart3 (i2c connector)
Software Serial has been tested to work bi-directionally at 9600 and 115200
using pins 6 and 63 on J5, and unidirectionally (write only) at 250000.
The code used to test was Teemuatlut's tmc2208 patch, and a few small changes to main used to echo recieved chars back to a host pc.
Uses PWM1 to directly control pins 4, 6 & 11 (servo 0, 1 & 3) and PWM1
generated interrupts to control other pins.
Interupt control of the servo pins had too much jitter so switched all
that we could to PWM1 direct control. The PWM1 direct control pins have
less than 1 microsecond pulse width jitter while the interrupt
controlled ones can have 20+ microseconds of jitter.
Also added insurance to the servo code in the "disable servo after move"
section.
* LCD_UBL_memory_slot_corrections
Changed the memory slot edit function to work with the
`settings.calc_num_meshes()`
* Add a little more safety margin...
* More corrections
Error handling when the EEPROM is not available.

Re-ARM has been tested. AVR has not been tested.
1) moved all cpu specific items to files in the low level HAL directory
for that CPU (pinDebug_Re-ARM.h & pinsDebug_AVR_8_bit.h
2) added pinsDebug.h to the top level directory
3) modified HAL_pinsDebug.h to select the correct support file for the
selected CPU
4) Patched sanitycheck to stop throwing false errors. A long term
solution will be done
5) misc changes & bug fixes
arduino.cpp - included macros.h to fix a missing definition
pinmap_re-arm.h - removed a duplicated line.
pinmapping.h - changed from "ENABLED" to "defined" to fix a compile
error
