Implement automatic extruder/cold-end fan control based on temperature

Browse source 
This change allows fan outputs to automatically turn on/off when the
associated nozzle temperature of an extruder is above/below a threshold
temperature.
Multiple extruders can be assigned to the same pin in which case the fan
will turn on when any selected extruder is above the threshold.
It also makes the M42 command compatible with the M106/M107 command.
The majority of the logic in this change will be evaluated by the
compiler at build time (i.e, low code space requirements).

Differences and additions to the already good Sprinter firmware:
================================================================ The default baudrate is 250000. This baudrate has less jitter and hence errors than the usual 115200 baud, but is less supported by drivers and host-environments.
*Look-ahead:*
Differences and additions to the already good Sprinter firmware:
Marlin has look-ahead. While sprinter has to break and re-accelerate at each corner, ================================================================
lookahead will only decelerate and accelerate to a velocity,
so that the change in vectorial velocity magnitude is less than the xy_jerk_velocity. *Look-ahead:*
This is only possible, if some future moves are already processed, hence the name.
It leads to less over-deposition at corners, especially at flat angles. Marlin has look-ahead. While sprinter has to break and re-accelerate at each corner,
lookahead will only decelerate and accelerate to a velocity,
*Arc support:* so that the change in vectorial velocity magnitude is less than the xy_jerk_velocity.
This is only possible, if some future moves are already processed, hence the name.
Slic3r can find curves that, although broken into segments, were ment to describe an arc. It leads to less over-deposition at corners, especially at flat angles.
Marlin is able to print those arcs. The advantage is the firmware can choose the resolution,
and can perform the arc with nearly constant velocity, resulting in a nice finish. *Arc support:*
Also, less serial communication is needed.

*Temperature Oversampling:* Marlin is able to print those arcs. The advantage is the firmware can choose the resolution,
and can perform the arc with nearly constant velocity, resulting in a nice finish.
To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged. Also, less serial communication is needed.
*AutoTemp:* *Temperature Oversampling:*
If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly. To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged.
Usually, higher speed requires higher temperature.
This can now be performed by the AutoTemp function *AutoTemp:*
By calling M109 S<mintemp> T<maxtemp> F<factor> you enter the autotemp mode.
If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly.
You can leave it by calling M109 without any F. Usually, higher speed requires higher temperature.
If active, the maximal extruder stepper rate of all buffered moves will be calculated, and named "maxerate" [steps/sec]. This can now be performed by the AutoTemp function
The wanted temperature then will be set to t=tempmin+factor*maxerate, while being limited between tempmin and tempmax. By calling M109 S<mintemp> T<maxtemp> F<factor> you enter the autotemp mode.
If the target temperature is set manually or by gcode to a value less then tempmin, it will be kept without change.
Ideally, your gcode can be completely free of temperature controls, apart from a M109 S T F in the start.gcode, and a M109 S0 in the end.gcode. You can leave it by calling M109 without any F.
If active, the maximal extruder stepper rate of all buffered moves will be calculated, and named "maxerate" [steps/sec].
*EEPROM:* The wanted temperature then will be set to t=tempmin+factor*maxerate, while being limited between tempmin and tempmax.
If the target temperature is set manually or by gcode to a value less then tempmin, it will be kept without change.
If you know your PID values, the acceleration and max-velocities of your unique machine, you can set them, and finally store them in the EEPROM. Ideally, your gcode can be completely free of temperature controls, apart from a M109 S T F in the start.gcode, and a M109 S0 in the end.gcode.
After each reboot, it will magically load them from EEPROM, independent what your Configuration.h says.

You can write to file in a subfolder by specifying a similar text using small letters in the path.
If you place a file auto[0-9].g into the root of the sd card, it will be automatically executed if you boot the printer. The same file will be executed by selecting "Autostart" from the menu. Also, backup copies of various operating systems are hidden, as well as files not ending with ".g".
First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.
*SD card folders:*
*Endstop trigger reporting:*
If you place a file auto[0-9].g into the root of the sd card, it will be automatically executed if you boot the printer. The same file will be executed by selecting "Autostart" from the menu.
If an endstop is hit while moving towards the endstop, the location at which the firmware thinks that the endstop was triggered is outputed on the serial port. First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.
This is useful, because the user gets a warning message.
However, also tools like QTMarlin can use this for finding acceptable combinations of velocity+acceleration. *Endstop trigger reporting:*
*Coding paradigm:* If an endstop is hit while moving towards the endstop, the location at which the firmware thinks that the endstop was triggered is outputed on the serial port.
This is useful, because the user gets a warning message.
Not relevant from a user side, but Marlin was split into thematic junks, and has tried to partially enforced private variables. However, also tools like QTMarlin can use this for finding acceptable combinations of velocity+acceleration.
This is intended to make it clearer, what interacts which what, and leads to a higher level of modularization.
We think that this is a useful prestep for porting this firmware to e.g. an ARM platform in the future. *Coding paradigm:*
A lot of RAM (with enabled LCD ~2200 bytes) was saved by storing char []="some message" in Program memory.
