[orca-list] Regarding the migration to Python 3

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

As you know, I try really hard to keep even our unstable branch stable.
In that spirit, since we are very early in the unstable cycle, and since
I just did the 3.5.1 release, I have begun doing the work to migrate
Orca from Python 2 to Python 3. It's a work in progress, but a fast
moving one.

What this means (and doesn't mean) for you:

* This will have no impact on the orca-xdesktop branch or the 3.4.x
  branch because those branches are stable. This only impacts master,
  a.k.a. GNOME 3.5.x.

* It ain't Python 3 until configure.ac says so. <grins> In particular,
  I'm starting with the low risk, should work just the same with 2.7,
  changes. Nearly all of those have been committed. Then I'm going to
  do the "shouldn't break anything in theory" changes. Hopefully those
  will be bug free, but there's always a chance of a regression. I'll
  probably do some of those tonight. Lastly I will do the changes which
  require Python 3 and bump the minimal required version of Python. I
  am aiming to do those this week so that you all can beat on it a bit
  before the next unstable release (3.5.2).

Please let me know if you have any questions, and thanks in advance for
your continued testing and feedback!

Take care.
