AnHardt 88b38eafd8 Endstop interrupt refinement 
At the start of a move, check if the endstops are already triggered.
The 'change' interrupts will not see a change if already triggered.

Scott Lahteine eb120e518c Followup to new endstop interrupts feature 
- Fix typos, verbiage
- Fix naming of `setup_endstop_interrupts`
- Some formatting, indentation, spacing

AnHardt f3eee02596 Introduce endstop interrupts 
If ENDSTOP_INTERRUPTS_FEATURE is enabled this tries to set up interrupt routines
for all used endstop pins. If this worked without errors, `endstops.update()` is called
only if one of the endstops changed its state.

The new interrupt routines do not really check the endstops and react upon them. All what they
do, is to set a flag if it makes sense to call the endstop test we are used to.

This can be used on:
* ARM (DUE) based boards - all pins can raise interrupts,
* RAMPS - all 6 endstop pins plus some other on EXT-2 can raise interrupts,
* RAMPS based boards - as long the designers did not change the pins for the endstops or at least left enough,
* all boards, if there are enough pins that can raise interrupts, and you are willing/able to swap with pins dedicated to other purpose.

Sebastianv650 cdc18f8c22 Remove useless line from stepper ISR 
The flag is already set inside planner.get_current_block(). Doing it
twice isn't making it better..

Sebastianv650 f9bea7968f BugFix for incorrect E-speed calculation 
The extrusion speed was wrong due to a not high enough precision of
esteps to XY steps, therefore now the target float values are used to
calculate the ratio between XY movement and extrusion speed.
The e_speed_multiplier8 was replaced by an absolute multiplier called
abs_adv_steps_multiplier8, therefore one multiplication and bitshift can
be saved inside the stepper ISR. Due to this, also extruder_advance_k is
better suited inside the planner and not the stepper files any more.
