* Add GFX overlay to UBL mesh edit
Fixed misplaced HAS_TEMP_BED in dogm_bitmaps.h
rename _lcd_babystep_zoffset_overlay to _lcd_zoffset_overlay_gfx and move it out of BABYSTEP_ZPROBE_OFFSET to we can use it for over things. Add this function into UBL mesh edit screen.
update all Configuration.h to add ENABLE_MESH_EDIT_GFX_OVERLAY
* Add Sanity to UBL insanity
Need to check for DOGLCD otherwise error out.
* 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
