GDB 8.3 release update (2019-04-08)

[Joel Brobecker <brobecker at adacore dot com>]

Hello,

Here a  quick update. No change in terms of the previously known
issues:

   * [TomT] Control characters in source causes infinite loop
     https://sourceware.org/ml/gdb-patches/2019-03/msg00611.html

However, I had since then identified what I consider to also be
a blocking problem:

   * [JoelB] GDB crash on Windows native

	What happens is that we're making the assumption that the thread
        that gets the process-exit notification (as opposed to the
        thread-exit one) is the same as the thread that we got for
        the process-creation notification. That assumption turns out
        to be false, and leads eventually to a failed assertion.
        I have a workaround which seems to work well, but it left
        some open questions I want to research before posting
        the patch.

        I don't think I'll have much time this week, unfortunately.
        Maybe this weekend.

I spoke to Tom, and he agrees the styling patch is block as well.
So I think we should hold the 8.3 release a little longer. Hopefully
both of us will have a bit of time to look into this sooner, rather
than later.
