Make block_buffer_runtime_us volatile

`block_buffer_runtime_us` is mangled in the planner and in the stepper-ISR.
So it needs to be volatile and interrupt protected.

Slightly shrink jerk and advance code

Update french translation (LIGHTS str)

Simplify long_move()

We are not really interested in, if there are blocks.
All information we need is in `block_buffer_runtime_us`.

Update language_de.h

Suppress warnings, etc

Patch long_move()

Remove redundant "E", etc plan B

While the last move in the planner_buffer is running
it's duration is already subtracted from block_buffer_runtime_us.

#define MSG_ENDSTOP_ABORT  doesn't fit in Display 
See https://github.com/MarlinFirmware/Marlin/issues/5401#issuecomment-265714487

・Suppress warnings
・Remove unused variable "did_update"

Sanity-check inverting for Z probe and Z endstop

`Z_MIN_ENDSTOP_INVERTING` must match `Z_MIN_PROBE_ENDSTOP_INVERTING`
when using `Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN`.
This is easy to overlook.
