This PR will add a new audit, specifically for spack package homepage urls (and eventually
other kinds I suspect) to see if there is an http address that can be changed to https.
Usage is as follows:
```bash
$ spack audit packages-https <package>
```
And in list view:
```bash
$ spack audit list
generic:
Generic checks relying on global variables
configs:
Sanity checks on compilers.yaml
Sanity checks on packages.yaml
packages:
Sanity checks on specs used in directives
packages-https:
Sanity checks on https checks of package urls, etc.
```
I think it would be unwise to include with packages, because when run for all, since we do requests it takes a long time. I also like the idea of more well scoped checks - likely there will be other addresses for http/https within a package that we eventually check. For now, there are two error cases - one is when an https url is tried but there is some SSL error (or other error that means we cannot update to https):
```bash
$ spack audit packages-https zoltan
PKG-HTTPS-DIRECTIVES: 1 issue found
1. Error with attempting https for "zoltan":
<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Hostname mismatch, certificate is not valid for 'www.cs.sandia.gov'. (_ssl.c:1125)>
```
This is either not fixable, or could be fixed with a change to the url or (better) contacting the site owners to ask about some certificate or similar.
The second case is when there is an http that needs to be https, which is a huge issue now, but hopefully not after this spack PR.
```bash
$ spack audit packages-https xman
Package "xman" uses http but has a valid https endpoint.
```
And then when a package is fixed:
```bash
$ spack audit packages-https zlib
PKG-HTTPS-DIRECTIVES: 0 issues found.
```
And that's mostly it. :)

- [x] add `concretize.lp`, `spack.yaml`, etc. to licensed files
- [x] update all licensed files to say 2013-2021 using
`spack license update-copyright-year`
- [x] appease mypy with some additions to package.py that needed
for oneapi.py
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
