Add a fully functional STM32F1 port, currently mostly targeting STM32F103
microcontrollers. This requires an 8 MHz XTAL. The maximum possible step rate
is around 282K steps per second.
This uses stm32flash to burn the firmware. The bootloader needs to be started
by setting BOOT0 to 1 and resetting the MCU. There is no automatic bootloader,
unlike on Arduino.

Add support for compiling the Klipper micro-controller code as a
real-time process capable of running on standard Linux systems.

Allow the micro-controller code to be built without support for
regular gpio pins. In this case, the code for endstops, steppers, and
gpiocmds will be disabled.

This adds basic support for running on the Atmel SAM3x8e
micro-controllers that are found in the Arudino Due boards.

On faster MCUs the step and unstep events may be too close for the
stepper motor driver. Add a CONFIG_NO_UNSTEP_DELAY build option and
support the case where it is not set. This allows faster MCUs to
schedule two events for each step (one for the step and one for the
unstep).

Some boards may not support hardware based PWM. Update the build so
that those commands do not need to be compiled if they are not
available.

Some boards may not support SPI transfers. Update the build so that
those commands do not need to be compiled if they are not available.

Some boards may not support the ADC hardware. Update the build so
that those commands do not need to be compiled if they are not
available.
