GDB 9.1 release -- 2020-01-17 update

[Joel Brobecker <brobecker@adacore.com>]

Hi everyone,

I am hoping that we'll soon be able to push this one out the door!
We're getting closer, with one last minute addition that I think
we should indeed evaluate:

  - [IanB/PedroA] output out of order / issue with filtered/unfiltered output order
    https://sourceware.org/ml/gdb-patches/2019-11/msg00859.html

    Affects cgdb via annotations:
    https://sourceware.org/bugzilla/show_bug.cgi?id=25190

    Not sure if blocking or not, since there seems to be a workaround;
    or perhaps the workaround is OK for the annotations, but doesn't
    work so well for other situations?

Still Open:

  - [Eliz/NickA/JoelB] libtcf fails to build on MinGW
    https://sourceware.org/bugzilla/show_bug.cgi?id=25155

    The only issue left to fix is the issue with errno.
    Nick Alcock provided a prototype patch, and said he would
    inform us when the final patch is pushed. I privately sent
    a request for info earlier today.

Fixed Since the last update (2020-02-02):

  - [Andrew] unexpected disassembly output in backtrace
    https://sourceware.org/ml/gdb-patches/2019-12/msg01007.html

  - [Christian] Unable to build GDB on recent MinGW due to _FORTIFY_SOURCE
    https://sourceware.org/ml/gdb-patches/2019-12/msg00787.html

  - [Joel/Tom/Simon] Report error if trying to build GDB in tree
    https://www.sourceware.org/ml/gdb-patches/2020-01/msg00554.html
    https://www.sourceware.org/ml/gdb/2019-12/msg00034.html
