[Buildroot] [PATCH 1/1] package/ffmpeg: bump version to 4.3

[Yann E. MORIN <yann.morin.1998@free.fr>]

Bernd, All,

On 2020-06-20 23:34 +0200, Bernd Kuhls spake thusly:
> Added patch to fix build without ssse3.
> 
> Updated license hash due to various changes since August 2019, these
> changes are unrelated to buildroot:

That's wrong: any change in the licensing terms *is* worth explaining.
Blindly changing the license hashes without explaining what has changed
makes the hashes useless.

So I've expanded the commit log with a summary of those changes.

Plus, see below...

The SoB lines are representing the chain of who did what with a patch.
So, the correct ordering is the following:

    Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
    [bernd.kuhls at t-online.de:
      - retrieved from upstream patchwork:
        https://patchwork.ffmpeg.org/project/ffmpeg/patch/20200223122256.23402-1-michael at niedermayer.cc/
    ]
    Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de>

Which means:

    1. Michael authored the patch
    2. Bernd got it from somewhere
    3. Bernd propagated the patch

And since I was also involved in fixing that, I've added:

    [yann.morin.1998 at free.fr: fix reference to patchwork and SoB order]
    Signed-off-by: Yann E. MORIN <yann.morin.1998@free.fr>

This now provides a clear history of the patch, where it originates
from, who did what with it, and in which order.

Regards,
Yann E. MORIN.
