GDB 8.3 release update (2019-04-30)

[Joel Brobecker]

Hello,

I think the following got fixed since the last update:

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

     Fixed by: Fix "list" when control characters are seen
     https://www.sourceware.org/ml/gdb-patches/2019-04/msg00158.html

   * [JoelB] GDB crash on Windows native
     https://www.sourceware.org/ml/gdb-patches/2019-04/msg00279.html

Are there any other issues that would be blocking before we create
the GDB 8.3 release?

   - I heard that there might be one known issue with styling
     that Tom tried to look at but couldn't reproduce?

   - I also see that we have the following patch waiting for review:

       [PATCH + 8.3] Don't derive partial_symbol from general_symbol_info
       https://www.sourceware.org/ml/gdb-patches/2019-04/msg00489.html

     The patch seems simple and safe, but I would need more study time
     to convince myself that there aren't other approaches that might
     be more interesting to take. Was anyone planning on reviewing it?

Anything else I might have missed?

Thanks you!
