All changes were created by running
"pyupgrade --py3-only --keep-percent-format"
and committing the results. I have not touched string formatting for
now.
- use set literals
- simplify .format() parameter naming
- remove __future__
- remove default "r" mode for open()
- use OSError rather than compatibility aliases
- remove stray parentheses in function(generator) scopes
Invoke create_zipapp.py from the root of the repository and it will
create a minimal zipapp with only the mesonbuild module code and a
__main__.py directly copied from meson.py
The meson.py launcher already tracks the desired entry point, and its
only other effect is to add the mesonbuild directory to the path if it
exists, which it won't in the zipapp. So there's no need to duplicate
this into another __main__.py
