RPM 4.19 now requires 2 %s to escape a single literal % in the filelist.
The test has been adjusted to actually run our code
instead of only verifying the assumptions.

python3-devel is not installed, hence the conditional needs to be on python3.
It only "worked" with toml because toml was pulled as a transitive dependency.

This makes the tests work on EL 9 and Fedora 36.
- Move metadata to setup.cfg in self-referential extras tests
- Skip tests for pyproject.toml [project] metadata when setuptools < 60

Dependencies are recorded to a text file that is catted at the end.
This should prevent subtle bugs like https://bugzilla.redhat.com/2183519 in the future.

An incomplete .dist-info directory in $PWD can confuse tests in %check.
For example, virtualenv uses importlib.metadata to load its
entry points and it does not work when it finds a virtualenv...dist-info without them.

When the build backend prints to stdout via non-Python means,
for example when a setup.py script calls a verbose program via os.system(),
the output leaked to stdout of %pyproject_buildrequires was treated as generated BuildRequires.
Fore example, if the setup.py script has:
rv = os.system('/usr/bin/patch -N -p3 -d build/lib < lib/py-lmdb/env-copy-txn.patch')
(From https://github.com/jnwatson/py-lmdb/blob/py-lmdb_1.0.0/setup.py#L117)
The stdout of /usr/bin/patch leaked to stdout of %pyproject_buildrequires:
[lmdb-1.0.0]$ /usr/bin/python3 -Bs /usr/lib/rpm/redhat/pyproject_buildrequires.py --python3_pkgversion 3 2>/dev/null
python3dist(setuptools) >= 40.8
python3dist(wheel)
patching file lmdb.h
patching file mdb.c
python3dist(wheel)
patching file lmdb.h
patching file mdb.c
This resulted in DNF errors like this:
No matching package to install: 'lmdb.h'
No matching package to install: 'mdb.c'
No matching package to install: 'patching'
Moreover, it resulted in bogus BuildRequires that may have existed (e.g. "file").
By replacing the usage of contextlib.redirect_stdout
(which only redirects Python's sys.stdout)
with a custom context manager that captures stdout on file descriptor level
(in addition to Python's sys.stdout),
we avoid this leak.
File descriptor magic heavily inspired by the capfd pytest fixture.

pyproject-srpm-macros is intended to be installed in the default buildroot.
That way, no explicit BuildRequires for pyproject-rpm-macros are required,
as long as %pyproject_buildrequires is used in %generate_buildrequires.
When only pyproject-srpm-macros is installed, the minimal implementation of
%pyproject_buildrequires generates a dependency on pyproject-rpm-macros.
When pyproject-rpm-macros is installed, it overrides the implementation
of %pyproject_buildrequires with the full one.
Note that in Fedora, pyproject-rpm-macros is required by python3-devel,
but not in RHEL.
This allows us to keep pyproject-rpm-macros in the RHEL CRB repository.

That way, if a package (such as python-tox) uses it,
the patches in dist-git are available.
In the future, it also allows us to add patches without URLs to our tested spec files.

The new %py3_test_envvars macro was added
to remove duplication of environment variables used in %check.
We reuse it in %tox to gain support e.g. for PYTEST_XDIST_AUTO_NUM_WORKERS.
However, we keep support for platforms where the macro is not yet available,
not to be forced to backport %py3_test_envvars everywhere right away.
Technically, this should change little, but it sets CFLAGS and LDFLAGS now,
hence a new Y version.

Before:
usage: %pyproject_buildrequires [-w] [-R] [-e TOXENVS] [-t] [-x EXTRAS] [-N] [REQUIREMENTS.TXT ...]
After:
usage: %pyproject_buildrequires [-x EXTRAS] [-t] [-e TOXENVS] [-w] [-R] [-N] [REQUIREMENTS.TXT ...]
The order was determined as:
0. suppressed options
1. extras, the easiest way to specify test deps (x)
2. tox related options (te)
3. build wheel, as it is provisional (w)
4. "disablers" (RN)
5. varargs are always listed last
Previous order was pretty much random.

When certain modules are deliberately not included into the built RPM,
they shouldn't be listed in the list of qualified module names which are
used by %pyproject_check_import to test importability of the
distribution.

Files still need to be marked as License-File to be considered %license,
but if their path in METADATA is specified relative to dist-info/licenses,
they are correctly recognised.
This makes License-Files specified by hatchling 1.9.0+ marked as %license.
