GDB 12 preparation -- 2022-03-06 update

[Joel Brobecker <brobecker@adacore.com>]

Hi everyone,

We are making very good progress, it seems, on the two issues
we have identified for GDB 12, so if things continue this way,
we might be on track to create our first pre-release around
the time we were targetting, which is March 20-25 (repeated
at the end of every message, just for the record)!

There has also been ...

    https://sourceware.org/bugzilla/show_bug.cgi?id=28616

... where I wasn't sure why it was marked GDB 12, and have been
trying to reach out to the person who created the PR. I've tried
a different email which I think will work. Given that I'm not
seeing progress on this PR either, I'm hoping this one isn't
going to be deemed critical (it does seem to happen in unusual
circumstances, but workarounds once hist are unclear at the moment).

That's it for this week. Let's see where we're at at the end
of next week :).

  * TBC: [BarisA/AndrewB] <PR cli/28833>
    Ctrl-D distorts GDB prompt
    https://sourceware.org/bugzilla/show_bug.cgi?id=28833


        Baris requested that we consider the bug above, which seems
        to be a GDB 11 regression for Baris.

        IIUC, Andrew fixed the issue in upstream's readline, and
        now we just need to backport it.

  * [AndrewB] create GDB/MI commands using python

        Explicit request to include in GDB 12; accepted as the patches
        were sent prior to the start of the GDB 12 release process.

Reminder: Tentative Schedule:
-----------------------------

  - GDB 12 branching: ~Mar 20-25;
  - GDB 12.1 release 2 weeks later, so early Apr.
