reprap: Progress
Now the reprap board has fake stepper motors that know their position,
with endstops (they work with Marlin) also there is a way to use
arduidiot pins numbers and remap them to AVR pins..
There is a prototype "heatpot" part that will be used to collect
source and drain of heat and calculafe a temperature.
Also added mongoose embedable web server. The current plan is to
use WebGL to render the graphics of the 3D printer... altho it's
not entirely sure as yet.

New example board: reprap
Proto shell for a reprap emulator. Currently can run Marlin, up to a point
There are lots of stuff to add, but with a bit of luck we could use the
"pins.h" of the firmware itseld to configure the simavr board, and
have it "adapt" to various hardware boards.
Currently the fake thermistor has been moderately tested, and seems to work.
It needs more work, like linear extrapolation, target temps etc.

uart_pty: Added a debug terminal
You can now launch an xterm with picocom by setting environment

Also, the uart_pty symlinks the pty pathname to /tmp/simavr-uart-X
so you can rely on a constant pathname.

uart_pty: New part

Properly implemented flow control too, do it's safe at any speed.

Makefile: Generate config files
The Makefile now tries to detect the cores that can
be built using the current avr-gcc install. This allows
simavr to be built with older toolchain that don't have
the latest cores. Like arduidiot.
It also allows generation of an automated core list for
simavr so the run_avr and others don't have to have an
explicit list of cores. They are now autodetected.

cycle_timers: Big rework
Removed the old bitfield, implemented a sorted list. Timers
get added to the list by (reverse) order of execution do acts
as a stack of timers to run and pop out.
This considerably simplifies the code, and also makes the code
that test for the next timer to run very small and efficient.
This should make cycle_timers a lot more scalable, since they are
used for many more uses than they were originaly designed for.

general: Introduce two new headers
Split the cycle/usec conversion code from the cycle_timer
