Migrate wiki.sagemath.org to trac.sagemath.org/wiki

[mkoeppe]

As proposed in ​https://groups.google.com/g/sage-devel/c/Acy5nNZWaUA/m/DuqGh3JkCwAJ and ​https://groups.google.com/g/sage-devel/c/4ysVRpYGU_E

The ​Trac wiki markup appears to understand most of the old Sage wiki's markup, except:

• In section headers, CamelCase words need to be escaped with "!"
• edit the markup for included images
  • {{https://patchbot.sagemath.org/svg/Pending||width=48}} changes to [[Image(https://patchbot.sagemath.org/svg/Pending, width=48)]]
• Replace <<TableOfContents>> by [[PageOutline]]

Also we can simplify some markup by replacing links to Trac tickets by just #....

• A command that helps with this:

  sed 's/<<TableOfContents[()]*>>/[[PageOutline]]/;s,\[\ 
  [https://trac.sagemath.org/ticket/\([0-9]*\)|#\1\]\],#\1,g;/^=/s/ \ 
  ([A-Z][a-z][a-z]*[A-Z]\)/ !\1/g;' INPUT > OUTPUT
  

• ​https://trac-hacks.org/wiki/MoinToTracScript (untested)

We also audit/update our documentation regarding links to the wiki.

$ git grep 'wiki[.]sage'

Please don't. In terms of infrastructure, the wiki is pretty well hosted, while the VM that hosts the trac+wiki is unmaintained, so this looks like a regression to me (at least right now).

I think that trac is better, as it allows contributions with github logins. And the bus factor of the present wiki hosting is rather small.

[mkoeppe]

It's critical that we get rid of the old Sage wiki. As Dima says - it excludes new developers.

Trac is maintained because it has to be (thanks to all who keep it running!) The wiki part of it places no additional burden on maintaining Trac.

[mkoeppe]

Some pages, for example ​https://wiki.sagemath.org/SageMathExternalPackages, are written in RST.

The Trac wiki also supports RST - ​https://trac.sagemath.org/wiki/WikiRestructuredText - but it looks like it is not activated.

@dimpase, could you install docutils (as per ​https://trac.sagemath.org/wiki/WikiRestructuredText#Requirements)?

@tmonteil, would you be able to provide me with a snapshot of the moinmoin wiki data, so I can try out the script ​https://trac-hacks.org/wiki/MoinToTracScript?
