SLNX is a new XML-based file-format for .NET based solutions, replacing
the older proprietary SLN file-format.
Unlike SLN-files, it is merge-friendly and expected to become the new
de-facto standard for working with .NET projects. This commit adds
support for SLNX-schema to 'nxml-mode'.
The schme provided has been synthesized using the official XSD-schema
definition:
https://github.com/microsoft/vs-solutionpersistence/blob/main/src/Microsoft.VisualStudio.SolutionPersistence/Serializer/Xml/Slnx.xsd
This schema was then converted to RNG using XSDtoRNG.xsl:
https://github.com/epiasini/XSDtoRNG
The RNG schema was then converted to RNC using the trang CLI-tool:
https://relaxng.org/jclark/trang.html
* etc/schema/dotnet-slnx.rnc: New file.
* etc/schema/schemas.xml: Add Slnx schema.
* lisp/files.el (auto-mode-alist): Add association for SLNX files.
(Bug#79379)
* etc/schema/dotnet-appconfig.rnc:
* etc/schema/dotnet-packages-config.rnc:
* etc/schema/dotnet-packages-props.rnc:
* etc/schema/dotnet-resx.rnc:
* etc/schema/msbuild.rnc:
* etc/schema/nuget.rnc:
* etc/schema/nuspec.rnc: New files.
* etc/schema/README: Document copyright status of above new files.
* etc/schema/schemas.xml: Use above new files to support Mono/.NET
development related XML files.

* Use the LibreOffice Relax-NG files since they include a hack to
support 1.2.
* rng source:
https://raw.githubusercontent.com/freedesktop/libreoffice-core/master/
schema/libreoffice/OpenDocument-schema-v1.3%2Blibreoffice.rng
* translation to rnc with trang:
trang -I rng -O rnc OpenDocument-schema-v1.3+libreoffice.rng \
OpenDocument-schema-v1.3+libreoffice.rnc
* etc/schema/schemas.xml: Recover the file, which was apparently
(mostly) removed by mistake by commit 165f738382 (bug#42851).
Copyright-paperwork-exempt: yes
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
