[Python-Dev] Devguide: Add a table summarizing status of Python branches

[Victor Stinner]

Hi,

I proposed a patch for the devguide to give the current status of all
Python branches: active, bugfix, security only, end-of-line, with
their end-of-life when applicable (past date or scheduled date)
http://bugs.python.org/issue26165

What do you think? Does it look correct?

We will have to update this table each time that the status of a
branch change. Hopefully, it's not a common event, so it will not
require a lot of work for release managers :-)
