Make use of pyinstaller hooks by creating a hook that updates how the
`mesonbuild` import functions.
This is more or less the same as passing a bajillion arguments to
pyinstaller's CLI, but allows the logic to be self-contained (and
reusable). It becomes more obvious what parts of the process pertain to
pyinstaller, and which parts pertain to MSI/pkg creation.
Fixes regression in commit 05b5a1e56f.
This added usage of another module in the python module's introspection
of `meson.exe runpython`, but the MSI packaging didn't adapt, causing it
to fail to be detected due to ImportError.
Fixes#9975
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
