Switch to Python3

[lemenkov]

Python 2.x no longer supported by upstream. Let's use Python3 explicitly.

Thanks for your contribution.

Did you actually test this, or is this only a simple 2to3 conversion?

[lemenkov]

Only b43-asm was tested (as a build-tool for OpenFWWF firmware). Other tools weren't tested. And yes this was done with 2to3.

/usr/bin/make -O -j12 V=1 VERBOSE=1
b43-asm ucode5.asm ucode5.fw --cpp-args -DDEBUG=1 -- --ivalext .fw --psize
ucode5.fw:  text = 1190 instructions (9520 bytes)
b0g0initvals5.fw:  177 values (968 bytes)
b0g0bsinitvals5.fw:  31 values (150 bytes)
Assembler info:
  Using start address 0

Ok. Hm.

Well, porting Python2 to 3 is hard, because every single line of code should be executed at least once to get a reasonable idea of whether it works or not.
I would expect at least a couple of str<->bytes conversions to be required here and there in addition to 2to3.

I would like to rather leave the ancient scripts as-is Python2 than breaking them. For example the debug scripts. Does anybody really use them today? And if so, do they do it on a modern system?

Can we split this PR into seperate PRs? One for fwcutter and one for disassembler? And can we leave the debug scripts as-is?

Sounds reasonable.

Sure thing. I'll split it and review it more thoroughly.
