[Simulavr-devel] Python 3 support in branch python_3

[Christian Taedcke]

Hello list,

i committed some changes regarding python 3 to the branch python_3.
The regression test and the examples should now work with python 2 and
3.

It would be good if someone could test this branch and review my
changes.

There is still one open issue in one example for python 3 (2 works):
PYTHONPATH=../../src/python /usr/bin/python3 example_io.py
atmega128:example_io.elf
...
simulation end: (t=15000000ns)
value 'timer2_ticks'=7
value 'port_val'=0x7e
value 'port_cnt'=3
