Have CI automatically check XEP-0001 conformance

[guusdk]

we should have a CI job which validates that changed or added files are conformant; e.g. that protoxeps come with the correct <number> and <status> values.

It would be great to collect a list of specific criteria to check for, so that it can be more easily converted into an implementation. I'll try to make a start, and would extend it with everything that's posted later on. I'm annotating with "warning" for something that CI should complain about but not block a merge, and "error" for things that must not be accepted.

Root folder xep-*.xml:

• [ ] /xep/header/number equals number in filename (error)
• [ ] There is a new /xep/header/revision block in changed files, containing a version, date, initials and remark (warning)

Inbox proto-XEPs:

• [ ] /xep/header/number is "xxxx" or "XXXX" (warning)
• [ ] /xep/header/status is "ProtoXEP" (warning)

Both types of XEP files:

• [ ] /xep/header/type is one of:
  • "Standards Track", "Informational", "Historical", "Humorous", "Procedural" (part of XEP-0001), "SIG Proposal", "SIG Formation" (only to be accepted in existing files) (error)
• [ ] /xep/header/status is one of:
  • "Active", "Deferred", "Deprecated", "Experimental", "Final", "Obsolete", "Proposed", "Rejected", "Retracted" (new and existing files), "Draft" (only to be accepted in existing files) (error)

Thank you Georg for the support!

• Estimated workload: 12 h
• Assumption: Knowledge of Github Automation
• [ ] Further clarification: Specification of the required validation rules

For this issue I think the deliverable just needs to be a script that accepts (at a minimum) a XEP .xml file, and returns a formatted list of issues (if any). I don't think CI stuff should be in scope (therefore the person working on this does not need any knowledge of Github automation).

I reformulated this with a clearer specification in #1235 and #1240, in order to have a more clean issue log. Re-open this if you disagree or comment over there or have anything to add.
