Add get_reactor(), lookup_object(), lookup_module_objects(), and
set_rollover_info() to the main Printer class so that callers do not
need to peek into the class' members. Similarly, add get_printer()
and get_name() methods to the ConfigWrapper class.

Change the update_command() call to use a new PinResolver class. In
that new class, verify that the same pin isn't referenced in two
different parts of the config using different aliases for the pin.

It's common for multiple steppers to use the same stepper enable
line. Detect this and only create a single digital_out oid on the
micro-controller.
Also, prohibit any other pin from being used multiple times in the
config file.

Always set the pin_params['type'] field on a pin lookup. Rename
parse_pin_desc() to lookup_pin() to make the change more clear.

The atmega168 and atmega328 need to define PE0 and PE1 in order to
support the 2 extra analog pins.
Also, support the arduino mappings for the atmega328.

Add support for reading analog values via the standard Linux IIO
interface. This can be used on Replicape boards to sample analog
input pins.

It's no longer necessary to use the TICKS() hack as the config
commands are now all generated after the mcu speed is known.

Allow multiple chips to provide pin mappings (not just the main mcu
chip). Move the pin parsing from the mcu.py code to pins.py and
support mapping from pin descriptions to their corresponding chips and
parameters.

The atmega328 is basically the same as the atmega168 - it just adds
some additional memory. Allow the chip to be selected during the
build.

Introduce a TICKS() macro during config parsing that will translate
time in seconds to time in clock ticks.

Use map_pins() to obtain the pin mapping - don't export
mcu_to_pins(). The functionality of mcu_to_pins() can be obtained by
calling map_pins() with name=None.

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