Roxy-3D 1451b7eacf UBL's Grid Based Leveling code
Pretty much...  The code is in place.  Still more work to do.    But it
has a lot of hooks and variables in other code, so commit and merge
before I pick up a million 'Conflicts'.

benlye f1d50ac1dc Fixing bilinear Z offset and G29 Z
The fix in #6251 for bilinear Z offset was flawed and broke the Z parameter of G29 for bilinear levelling.  This is reverted and a different fix is used for the double-addition of the Z-probe offset to the bilinear correction grid.

benlye 0a2b4f3486 Fix bilinear levelling z offset
Since run_probe was altered to return the probe Z position rather than the nozzle Z position bilinear levelling has been broken because the Z-offset has been applied twice - once in the run_probe function, and then again in the G29 code for bilinear levelling.

Bob-the-Kuhn 0934563b97 G38 optional double touch
Made the double touch portion a conditional compile based on the
PROBE_DOUBLE_TOUCH flag.

==============================================

Bugfix

The current G38 only stopped a move if it involved the Z axis.

Moved all the G38 code to it's own section and put it where it would
always be executed no matter what axis was moving or if the endstop was
enabled.

Also added a comment to configuration_adv to alert the user the double
tap had to be turned on.

==============================================

Change G38 back to using Z_MIN_PROBE

There's no Z_MIN endstop if Z_DUAL_ENDSTOPS is enabled and you have them
set to the top of the gantry.

G38 started out as using the Z_MIN_PROBE pin.  I don't remember why we
changed it to the Z_MIN endstop.

Bob-the-Kuhn 685ed5393a Bug Fix: Switching extruder tool change leaves Z in wrong position
The tool_change function saves the current_position to the destination
array soon after starting.  Later in the switching extruder section, the
destination array is modified when moving the Z axis up & down.  A later
section of tool_change moves the head back to the “original location”
using the destination array.  This later section assumes that the
destination array hasn’t been modified.

The fix is to save the destination Z position and then restore it after
the Z movements have completed.

Going back to using the current_position array for the switching
extruder Z axis moves (and  leaving the destination array untouched)
doesn’t fix the problem.

This bug was introduced by the “Make tool_change kinematic compatible”
commit # 847429eff4 which was merged on 10
Oct 2016 as part of PR 4982.

This bug was discovered in Issue 5966.

Addressing #5625

Bob-the-Kuhn 0369f97ec1 guaranteed BLTouch detection
To guarantee that the 5mS pulse from a BLTouch is recognized you need to
have the endstops.update() routine run twice in that 5mS period.

At 200 steps per mm, my system has problems  below a feedrate of 120 mm
per minute.

Two things were done to guarantee the two updates within 5mS:
1) In interrupt mode, a check was added to the temperature ISR.  If the
endstop interrupt flag/counter is active then it'll kick off the endstop
update routine every 1mS until the flag/counter is zero.  This
flag/counter is decremented by the temperature ISR AND by the stepper
ISR.

2) In poling mode, code was added to the stepper ISR that will make sure
the ISR runs about every 1.5mS.  The "extra" ISR runs only check the
endstops.  This was done by grabbing the intended ISR delay and, if it's
over 2.0mS, splitting the intended delay into multiple smaller delays.
The first delay can be up to 2.0mS, the next ones 1.5mS (as needed) and
the last no less than 0.5mS.

=========================================

BLTouch error state recovery

If BLTouch already active when deploying the probe then try to reset it
& clear the probe.

If that doesn't fix it then declare an error.

Also added BLTouch init routine to startup section

AnHardt d0e24e0876 Adaptive screen updates for all kinds of displays
The target here is to update the screens of graphical and char base
displays as fast as possible, without draining the planner buffer too much.

For that measure the time it takes to draw and transfer one
(partial) screen to the display. Build a max. value from that.
Because ther can be large differences, depending on how much the display
updates are interrupted, the max value is decreased by one ms/s. This way
it can shrink again.
On the other side we keep track on how much time it takes to empty the
planner buffer.
Now we draw the next (partial) display update only then, when we do not
drain the planner buffer to much. We draw only when the time in the
buffer is two times larger than a update takes, or the buffer is empty anyway.

When we have begun to draw a screen we do not wait until the next 100ms
time slot comes. We draw the next partial screen as fast as possible, but
give the system a chance to refill the buffers a bit.

When we see, during drawing a screen, the screen contend has changed,
we stop the current draw and begin to draw the new content from the top.
