lcd_erase_line() is called with argument, but the argument is ignored by lcd_erase_line().

If comparison between signed char(-128 ~ +127) and DIR_NAME_DELETED(uint8_t const 0XE5, it's +229),
it makes incorrect result.

Addition to #3140

diagonal_rod hadn't been used anywhere.

Extend stack_overflow_protection for lcd_move_e() and _lcd_level_bed() with
a refined method of 3050.

follow-up the commit 7326d63ce0
update Configration_adv.h of Hephestos2
delete unnecessary spaces

Addressing #2879. The M115 report should display `MACHINE_UUID` but it
always displays `UUID`.

Addressing #3085. If the target_temperature is set directly it never invokes or disables the timer set in `start_watching_heater`, so after _stopping a print_ or turning off _all heaters_ you could get a “Heating failed” error.

Expected behavior: After editing a value the menu should return to the
previous place with the edited item selected.
Actual behavior: Either the top (back) item from the previous screen is
selected, or the menu jumps up another level.
Solution: Pass the correct arguments to `lcd_goto_menu` on click when
editing a value.

rebased
corrected spelling
changed to #elif for error

Still with MIN_Z_HEIGHT_FOR_HOMING but con be done with (folder wide) search-replace when we have a better name.

Add 'ok' output for G29 actually closing the file.
Handle M110 when received without linenumber/checksumm.

update old comments
update or delete deprecated definitions
complement forgotten updates
adjust spacing
some cosmetic changes

- also by default use ${HOME}/Arduino as install directory which may be more
sane, especially with arduino packages provided by distributions
- bump arduino version to 106 (this seems to be useless)
- program firmware through the USB serial which is more comfortable way how
to program the firmware
- use 57600 programing speed by default which seems to be more reliable
with arduino bootloaders (at least with those shipped with the Melzi2 boards)
