Configs are always included via a config_wrapper.h now, and configs always
must include this safety-definition for a missing DEFINE_HEATER. Let's
simplify the configs by moving it to a common location.
You can reduce the max. power of each heater.
With the max_pwm value between 1 and 100% you reduce the active pwm.
For example you could reduce the power of your hotend.
My hotend for example is 12V 30W but connected to 24V. So it has
normally 120W. This is very huge. Setting the max_pwm to 25, it has
again ~30W.

Commit reviewer Traumflug's note:
- Rebased to current branch 'experimental', which adds
USE_INTERNAL_PULLDOWNS.
- Removed DEFINE_HOMING for now, this part isn't cooked, yet.
For example, it doesn't pass regression tests.
- Thank you very much for the contribution!
This allows to use EWMA_ALPHA in an #if clause, which is needed
for the next commit.
Review changes by Traumflug: made changes to comments more
complete, added rounding ("+ 500") and also adjusted Configtool
for the change.
(Ab)use the old Gen7 v1.3 configuration for this, as this is
rarely in use and because this board also happens to be the board
where the tested code was developed on.
Having a choice with a defined set of options is nice, but it
also requires these options to be #defined somewhere _before_
entering config.h. To keep class-like encapsulation, we'd need
two header files for each code unit, one for the options, another
one for the usual header.
That said, we use other examples of such options, e.g. CPU, F_CPU
or KINEMATICS. For CPU and F_CPU it works fine, because their
options are numbers or other values known by the compiler. For
KINEMATICS it kind of works, because this #define is used in only
one place ... and there it's suboptimal already, because no option-
set.
Anyways, I was unsure about this change and if it turns out to be
a poor decision later, it can be reverted.
Most work by Ruslan Popov, collected from various commits and
made compatible with regression tests by Traumflug.
Display test code is now enabled by #defining DISPLAY_BUS to
i2c_twi.
It happens all to often that a #define is added or removed here
or there, but some related files gets forgotten. Now at least
existence of all the #defines is cross-checked.
Until this commit, the Z axis is disabled after each move and
only enabled when the Z axis will move. Now you can enable this
as a feature. Some printer axes are too heavy or have a high
pitch which are not self locking. In that case simply do nothing.
It's now off by default.

The adjustments done were reverting customisations like moving
direction reversals (which depend on motor wiring) or custom
thermistor beta values. Everything else left as-is.
Implemented and tested for both platforms. This is quite a big
commit. Unlike with the previous changes to now choosable PWM
frequencies, all board configuration files and Configtool had
to be changed immediately to deal with the additional parameter
in DEFINE_HEATER() and keep AVR builds working (and regression
tests passing).
Especially at high frequencies the achieved one is only close,
but that's entirely sufficient for our purposes.
Test: the PWM frequency on the scope should be similar to the
one configures in the board file with DEFINE_HEATER().
Currently at a fixed frequency of 1 kHz and with a fixed duty
cycle of 10%, but PWM does work.
As it turns out, PIO0_11 is not usable for PWM, because its timer
is already in use for the Step timer, and had to be disabled for
Gen7-ARM.
Test: define a heater in board.gen7-arm.h and a square signal
of 1 kHz with 10% duty cycle should appear on the heater pin.
These were dropped accidentally, I assume, during the Configtool
template conversion. Without them the INTERCOM feature does not
compile and so board.gen3.h is broken.
Add the gen3 config to testcases and regressiontests to ensure
this does not drop again.
This has to work, else we can't provide default values for new
items.
Now loading a RAMPS board and just saving it results in an
identical file. Very well. Not so for other boards, because
disabled values still get lost.
