For reasons beyond me Python thinks it's a great idea to upgrade HEAD
requests to GET requests when following redirects. So, this PR adds a
better `HTTPRedirectHandler`, and also moves some ad-hoc logic around
for dealing with disabling SSL certs verification.
Also, I'm stumped by the fact that Spack's `url_exists` does not use
HEAD requests at all, so in certain cases Spack awkwardly downloads
something first to see if it can download it, and then downloads it
again because it knows it can download it. So, this PR ensures that both
urllib and botocore use HEAD requests.
Finally, it also removes some things that were there to support currently
unsupported Python versions.
Notice that the HTTP spec [section 10.3.2](https://datatracker.ietf.org/doc/html/rfc2616.html#section-10.3.2) just talks about how to deal
with POST request on redirect (whether to follow or not):
> If the 301 status code is received in response to a request other
> than GET or HEAD, the user agent MUST NOT automatically redirect the
> request unless it can be confirmed by the user, since this might
> change the conditions under which the request was issued.
> Note: When automatically redirecting a POST request after
> receiving a 301 status code, some existing HTTP/1.0 user agents
> will erroneously change it into a GET request.
Python has a comment about this, they choose to go with the "erroneous change".
But they then mess up the HEAD request while following the redirect, probably
because they were too busy discussing how to deal with POST.

The package.py assumed "+mpi" in many places, without checking for the variant.
This problem went undetected, as a hard dependency on scalapack pulled an mpi
implementation into the dependency chain (this is also fixed).
Also, the +mpi variant is used select between serial and parallel mode:
It has to enable MPI and ScaLAPACK: They are inter-dependent. Compile
fails because of checks for the other if the other is not enabled.

This adds super-lazy maintainer mode to `spack checksum`: Instead of
only printing the new checksums to the terminal, `-a` and
`--add-to-package` will add the new checksums to the `package.py` file
and open it in the editor afterwards for final checks.
This PR removes [end of life](https://endoflife.date/python) versions of Python from Spack. Specifically, this includes all versions of Python older than 3.7.
See https://github.com/spack/spack/discussions/31824 for rationale. Deprecated in #32615. And #28003.
For anyone using software that relies on Python 2, you have a few options:
* Upgrade the software to support Python 3. The `3to2` tool may get you most of the way there, although more complex libraries may need manual tweaking.
* Add Python 2 as an [external package](https://spack.readthedocs.io/en/latest/build_settings.html#external-packages). Many Python libraries do not support Python 2, but you may be able to add older versions that did once upon a time.
* Use Spack 0.19. Spack 0.19 is the last release to officially support Python 3.6 and older
* Create and maintain your own [custom repository](https://spack.readthedocs.io/en/latest/repositories.html). Basically, you would need a package for Python 2 and any other Python 2-specific libraries you need.
* Add a WindowsRegistryView class, which can query for existing
package installations on Windows. This is particularly important
because some Windows packages (including those added here)
do not allow two simultaneous installs, and this can be
queried in order to provide a clear error message.
* Consolidate external path detection logic for Windows into
WindowsKitExternalPaths and WindowsCompilerExternalPaths objects.
* Add external-only packages win-sdk and wgl
* Add win-wdk (including external detection) which depends on
win-sdk
* Replace prior msmpi implementation with a source-based install
(depends on win-wdk). This install can control the install
destination (unlike the binary installation).
* Update MSVC compiler to choose vcvars based on win-sdk dependency
* Provide "msbuild" module-level variable to packages during build
* When creating symlinks on Windows, need to explicitly specify when
a symlink target is a directory
* executables_in_path no-longer defaults to using PATH (this is
now expected to be taken care of by the caller)
Spec traversals can now specify a topological ordering. A topologically-
ordered traversal with input specs X1, X2... will
* include all of X1, X2... and their children
* be ordered such that a given node is guaranteed to appear before any
of its children in the traversal
Other notes:
* Input specs can be children of other input specs (this is useful if
a user specifies a set of specs to uninstall: some of those specs
might be children of others)
* `direction="parents"` will produce a reversed topological order
(children always come before parents).
* `cover="edges"` will generate a list of edges L such that (a) input
edges will always appear before output edges and (b) if you create
a list with the destination of each edge in L the result is
topologically ordered
* test_suite.py: speed up slow test by using mock packages
* Don't resolve the sha during unit-tests
* Skip long-running test that fails, instead of executing it
* uninstall: fix accidental cubic complexity
Currently spack uninstall runs in worst case cubic time complexity
thanks to traversal during traversal during traversal while collecting
the specs to be uninstalled.
Also brings down the number of error messages printed to something
linear in the amount of matching specs instead of quadratic.
