Add a new disinherit directive for extending packages

When you inherit from a package in Spack, you inherit all the metadata from its directives, including `version`, `provides`, `depends_on`, `conflicts`, etc. In some cases, you may not want this metadata. This PR adds a new `disinherit` directive that allows you to throw out things inherited from the base class. For example: ```python from spack.pkg.builtin.mpich import Mpich class MyMpich(Mpich): disinherit("versions") # don't inherit any versions from builtin Mpich version("5.0", "08721a102fefcea2ae4add8c9cc548df77e9224f5385ad0872a9150fdd26a415") version("6.0", "9cc39dd33dd4227bb82301d285437588d705290846d22ab6b8791c7e631ce385") ``` Without the `disinherit("versions")` directive, this package would have versions `5.0`, `6.0`, *and* anything inherited from `Mpich`. With it, this package has only versions `5.0` and `6.0`. You can `disinherit` any of: `conflicts`, `dependencies`, `extendees`, `patches`, `provided`, `resources`, `variants`, or `versions`. - [x] add new `disinherit directive` - [x] Two packages were modifying their `versions` dictionary in their constructors to achieve this, but this causes `spack url stats` to fail with a concurrent modification exception as it iterates over all packages. Fixed these to use `disinherit` instead. - [x] Update documentation - [x] Add tests

-Another advanced use-case of generated ``Makefile``\s is running a post-install
-command for each package. These "hooks" could be anything from printing a
-post-install message, running tests, or pushing just-built binaries to a buildcache.
-
-This can be accomplished through the generated ``[<prefix>/]SPACK_PACKAGE_IDS``
-variable. Assuming we have an active and concrete environment, we generate the
-associated ``Makefile`` with a prefix ``example``:
-
-.. code:: console
-
-   $ spack env depfile -o env.mk --make-prefix example
-
-And we now include it in a different ``Makefile``, in which we create a target
-``example/push/%`` with ``%`` referring to a package identifier. This target
-depends on the particular package installation. In this target we automatically
-have the target-specific ``HASH`` and ``SPEC`` variables at our disposal. They
-are respectively the spec hash (excluding leading ``/``), and a human-readable spec.
-Finally, we have an entrypoint target ``push`` that will update the buildcache
-index once every package is pushed. Note how this target uses the generated
-``example/SPACK_PACKAGE_IDS`` variable to define its prerequisites.

-Not all spack packages currently have Windows support. Some are inherently incompatible with the
-platform, and others simply have yet to be ported. To view the current set of packages with Windows
-support, the list command should be used via `spack list -t windows`. If there's a package you'd like
-to install on Windows but is not in that list, feel free to reach out to request the port or contribute
-the port yourself.
+Many Spack packages are not currently compatible with Windows, due to Unix
+dependencies or incompatible build tools like autoconf. Here are several
+packages known to work on Windows:
+
+* abseil-cpp
+* bzip2
+* clingo
+* cpuinfo
+* cmake
+* hdf5
+* glm
+* nasm
+* netlib-lapack (requires Intel Fortran)
+* ninja
+* openssl
+* perl
+* python
+* ruby
+* wrf
+* zlib

 .. note::
-   This is by no means a comprehensive list, some packages may have ports that were not tagged
-   while others may just work out of the box on Windows and have not been tagged as such.

+Package Inheritance
+--------------------------------
+
+Spack packages are Python classes, and you can use inheritance with them just as you can
+with any Python class. This is common when you have your own package :ref:`repository
+<repositories>` with packages that extend Spack's ``builtin`` packages.
+
+You can extend a ``builtin`` package like this:
+
+.. code-block:: python
+
+   from spack.pkg.builtin.mpich import Mpich
+
+   class MyPackage(Mpich):
+       version("1.0", "0209444070d9c8af9b62c94095a217e3bc6843692d1e3fdc1ff5371e03aac47c")
+       version("2.0", "5dda192154047d6296ba14a4ab2d869c6926fd7f44dce8ce94f63aae2e359c5b")
+
+Every repository registered with Spack ends up in a submodule of ``spack.pkg`` with a
+name corresponding to its :ref:`namespace <namespaces>`. So, if you have a different
+repository with namespace ``myrepo`` you want to import packages from , you might write:
+
+.. code-block:: python
+
+   from spack.pkg.myrepo.my_package import MyPackage
+
+   class NewPackage(MyPackage):
+       version("3.0", "08721a102fefcea2ae4add8c9cc548df77e9224f5385ad0872a9150fdd26a415")
+       version("4.0", "9cc39dd33dd4227bb82301d285437588d705290846d22ab6b8791c7e631ce385")
+
+^^^^^^^^^^^^^^^^^^^^^^^^
+``disinherit``
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+When you inherit from a package in Spack, you inherit all the metadata from its
+directives, including ``version``, ``provides``, ``depends_on``, ``conflicts``, etc. For
+example, ``NewPackage`` above will have four versions: ``1.0`` and ``2.0`` inherited
+from ``MyPackage``, as well as, ``3.0``, and ``4.0`` defined in ``NewPackage``.
+
+If you do not want your package to define all the same things as its base class, you can
+use the ``disinherit`` directive to start fresh in your subclass:
+
+.. code-block:: python
+
+   from spack.pkg.myrepo.my_package import MyPackage
+
+   class NewerPackage(MyPackage):
+       disinherit("versions")    # don't inherit any versions from MyPackage
+       version("5.0", "08721a102fefcea2ae4add8c9cc548df77e9224f5385ad0872a9150fdd26a415")
+       version("6.0", "9cc39dd33dd4227bb82301d285437588d705290846d22ab6b8791c7e631ce385")
+
+Now, ``NewerPackage`` will have **only** versions ``5.0`` and ``6.0``, and will not
+inherit ``1.0`` or ``2.0`` from ``MyPackage``. You can ``disinherit`` many different
+properties from base packages. The full list of options is:
+
+* ``conflicts``
+* ``dependencies``
+* ``extendees``
+* ``patches``
+* ``provided``
+* ``resources``
+* ``variants``
+* ``versions``

-You may have noticed that namespace notation for repositories is similar

-
-You could, for example, extend a ``builtin`` package in your own

-Spack repo namespaces are actually Python namespaces tacked on under

-implemented using Python's built-in `sys.path
-<https://docs.python.org/2/library/sys.html#sys.path>`_ search.  The
-:py:mod:`spack.repo` module implements a custom `Python importer
-<https://docs.python.org/2/library/imp.html>`_.
-
-.. warning::
-
-   The mechanism for extending packages is not yet extensively tested,
-   and extending packages across repositories imposes inter-repo
-   dependencies, which may be hard to manage.  Use this feature at your
-   own risk, but let us know if you have a use case for it.
