2.6 is the minimum Python version for what, exactly?  Is it for
building QEMU?

Note that qmp-shell is a tool for developers, not required for
building or running QEMU.  People who really want to run
qmp-shell on a python-2.6 system can still install argparse if
they want to use qmp-shell.

I could backport the code to optparse.  But should we add code
that relies on a deprecated module, if developers running Python
2.6 can install argparse?
