Frederik Rietdijk 76966f8ddd pythonPackages.pip-install-hook: remove --build option
Pip had the option --build to build in a custom or temporary directory.
Nowadays, pip just listens to TMPDIR, which we already set.

This option was deprecated and is removed in pip 20.3.

pythonPackages.pip: make reproducible (#102222)
The previous attempt wasn't covering all of the bases. It relied on
invoking that pip-install-hook, and didn't apply to pip itself.

The core issue is that the generated .pyc files embed some of the
temporary paths, which are randomly generated. See
https://r13y.com/diff/bf8c3ca3148ebff9ecf41f294cc60b9f209c006d49699e356969ff32d736f1c6-8806a7cca91fdd300e48736bfcd57c4d0b54c1cc2fd61609f35143170862b59c.html

In this new attempt, the approach is to patch the TempFile
implementation directly, so that it creates stable temporary
directories. We also assume that if SOURCE_DATE_EPOCH is set, we are in
a scenario where reproducible builds are desirable and enter that
branch.

Daniël de Kok 1e2b6695cf pythonPackages.setuptoolsBuildHook: do not build in an isolated environment
When a PEP 517 project file is present, pip will not install
prerequisites in `site-packages`:

https://pip.pypa.io/en/stable/reference/pip/#pep-517-and-518-support

For the shell hook, this has the consequence that the generated
temporary directory that is added to PYTHONPATH does not contain
`site.py`. As a result, Python does not discover the Python
module. Thus when a user executes nix-shell in a project, they cannot
import the project's Python module.

This change adds the `--no-build-isolation` option to pip when
creating the editable environment, to correctly generate `site.py`,
even when a `pyproject.toml` is present.

If these aren't defined, the stdenv defaults are used in the `*Phase`
case, or no extra phases are done, in the `*Phases` case.

John Ericson 2811b032d6 treewide: Make still dont* Variables are optional in most cases
Go beyond the obvious setup hooks now, with a bit of sed, with a skipped case:

 - cc-wrapper's `dontlink`, because it already is handled.

Also, in nix files escaping was manually added.

Frederik Rietdijk f7e28bf5d8 Split buildPythonPackage into setup hooks
This commit splits the `buildPythonPackage` into multiple setup hooks.

Generally, Python packages are built from source to wheels using `setuptools`.
The wheels are then installed with `pip`. Tests were often called with
`python setup.py test` but this is less common nowadays. Most projects
now use a different entry point for running tests, typically `pytest`
or `nosetests`.

Since the wheel format was introduced more tools were built to generate these,
e.g. `flit`. Since PEP 517 is provisionally accepted, defining a build-system
independent format (`pyproject.toml`), `pip` can now use that format to
execute the correct build-system.

In the past I've added support for PEP 517 (`pyproject`) to the Python
builder, resulting in a now rather large builder. Furthermore, it was not possible
to reuse components elsewhere. Therefore, the builder is now split into multiple
setup hooks.

The `setuptoolsCheckHook` is included now by default but in time it should
be removed from `buildPythonPackage` to make it easier to use another hook
(curently one has to pass in `dontUseSetuptoolsCheck`).
