Refactor the code so that message block framing, command parsing, and
command dispatch are distinct.

Some systems point python to python3 instead of python2 - explicitly
request python2 to avoid conflicts.

Make sure the heater.target_temp is set during the auto-tune test so
that the heater.set_pwm() command will allow the heater to be turned
on.

Add python-virtualdev to the list of system packages to be installed -
it's usually already installed, but it doesn't hurt to add it to the
list in case it isn't already installed.

The endstop_position is intended to support different values for each
stepper so that the individual tower heights can be configured.

Commit d0932009 introduced an error that could cause lost input in
cases where the sender did not wait for an "ok" message before sending
the next command.

Create add_printer_objects() functions in the fan, heater, extruder,
and toolhead modules. Create the necessary printer component objects
from this call instead of placing the code directly in klippy.py.

It appears this option is commonly needed on the at90usb1286 avr chip
(the printrboard requires it), so default it on.

Add a CONFIG_SIMULAVR option to the Kbuild menus and don't directly
prompt users for CONFIG_WATCHDOG or CONFIG_SERIAL_BAUD_U2X. The only
reason to disable these options would be if one were running on
simulavr. This simplifies the user visible menu options.
Also, only show CONFIG_CLEAR_PRESCALER for at90usb1286 chips.

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

Reorder the MCU list so that newer chips are at the top of the list.
This causes the very popular atmega2560 to be the default chip
selected.
Reorder the frequency list so that higher frequencies are at the top
of the list. Restrict the 20Mhz frequency to only chips that support
that speed. This causes the popular 16Mhz frequency to be the default
speed on AVR.

Avoid using linker magic to define the init, task, and shutdown
functions. Instead, use the compile_time_request system. This
simplifies the build and produces more efficient code.

Avoid generating unique ids via memory locations and linker scripts.
Instead, generate them using code produced by buildcommands.py.
Utilize gcc's ability to perform static string comparisons at compile
time to produce a unique id for each unique string.
This fixes a build failure on ARM introduced in 142b92b8. It also
reduces the complexity of the build.

The gpio_out_write() and gpio_out_setup() calls will check for zero
and non-zero, so it is not necessary to explicitly convert to 0/1 in
the stepper.c code.

On some architectures, gcc will allocate a register for inline
assembler with an "m" constraint. Use "i" to avoid that.

Change the range of values used for software PWM to avoid doing an
integer division in the main code.
