With the the current definition of echo_command I cannot compile RCBugFix (Arduino IDE 1.8.1) with the error "invalid conversion from 'const char*' to 'char*'". This change resolves that.
After wraparound, pwm_count <= pwm_mask holds, thus soft_pwm_X <= pwm_count
guarantees soft_pwm_X < pwm_mask is true, and the heater will be switched
off in the first branch.
Do not evaluate the pwm conditions a second time, this reduces the
instruction count (4 instructions per PWM) and text size (6 byte).

The compiler is not able to reuse the value of pwm_count, but reloads it
on every evaluation, if is stored in a static variable, as it cannot prove
it will be unchanged. A variable with local scope may not be modified from
the outside, so its value can be reused.
Doing so reduces text size and instruction count.

If dithering is enabled, the remainder of the soft_pwm_X duty value at
turnoff time is added to the next cycle. If e.g. the duty is set to 9 and
SCALE is set to 2, the PWM will be active for 8 counts for 3 cycles and
12 counts on each fourth cycle, i.e. the average is 9 cycles.
This compensates the resolution loss at higher scales and allows running
fans with SOFT_PWM with significantly reduced noise.

A 128 step PWM has 127 intervals (0/127 ... 127/127 duty). Currently, a
PWM setting of 1/127 is active for 2/128, i.e. double the expected time,
or, in general n+1/128 instead of n/127.
Fixes issue#6003.

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.
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.
ArduinoAddons has been removed from Marlin, remove any references to it.
Replace HARDWARE_SRC and HARDWARE_DIR with its expanded equivalents.

Instantiation of the static singleton instance thermalManager in general
requires locking, but we know its safe to do without.
Add -fno-threadsafe-statics to avoid using locking primitives, which
result in linking errors:
undefined reference to `__cxa_guard_acquire'
undefined reference to `__cxa_guard_release'
