Lumir Balhar 5f32aac09e New opt-in possibility to fix byte-compilation reproducibility 
A new script brp-fix-pyc-reproducibility creates an opt-in way of how to fix
problems with the reproducibility of byte-compiled Python files. The script
uses marshalparser [0] which currently doesn't provide solutions for all issues
but can fix at least problems with reference flags. For more info see
this Bugzilla [1].

If you want to use this new feature, you need to define
`%py_reproducible_pyc_path` to specify a path you want to fix `.pyc`
files in (recursively) and build-require /usr/bin/marshalparser.

if you forget to build-require the parser. The error message is:
```
+ /usr/lib/rpm/redhat/brp-python-bytecompile '' 1 0
Bytecompiling .py files below /builddir/build/BUILDROOT/tldr-0.5-2.fc33.x86_64/usr/lib/python3.9 using /usr/bin/python3.9
+ /usr/lib/rpm/redhat/brp-fix-pyc-reproducibility /builddir/build/BUILDROOT/tldr-0.5-2.fc33.x86_64
ERROR: If %py_reproducible_pyc_path is defined, you have to also BuildRequire: /usr/bin/marshalparser !
error: Bad exit status from /var/tmp/rpm-tmp.UUJr4v (%install)
```

A build fails if the parser is not able to parse any of the `.pyc` files.

And finally, if a build is properly configured it produces fixed `.pyc` files.

Currently, `.pyc` files in the tldr package contain a lot of unused reference flags:
```
$ dnf install -y tldr
$ marshalparser --unused /usr/lib/python3.9/site-packages/__pycache__/tldr.cpython-39.pyc
… long output …

203 - Flag_ref(byte=10102, type='TYPE_SHORT_ASCII_INTERNED', content=b'argparse', usages=0)
204 - Flag_ref(byte=10433, type='TYPE_SHORT_ASCII_INTERNED', content=b'__name__', usages=0)
205 - Flag_ref(byte=10463, type='TYPE_SHORT_ASCII_INTERNED', content=b'<module>', usages=0)
```

This new feature fixes them:

```
$ marshalparser --unused /usr/lib/python3.9/site-packages/__pycache__/tldr.cpython-39.pyc
<empty output>
