opencv 2.x has seen no release since July 2018 and all buildroot
packages are already compatible with opencv3 so drop it to ease the
addition of opencv4 which is not fully backward compatible with opencv3
as "a lot of C API from OpenCV 1.x has been removed.":

Add a patch to fix build without ssse3.
Update the license hash due to various changes since August 2019 [0]:
- some files were relicensed from GPL-2.0+ to LGPL-2.1+; no impact on
the licensing information;
- clarification about the licensing when linked with external
libraries, which now requires passing --enable-version3; Buildroot
is not concerned, because it passes --disable-version3;
- various clarification about applicable licensing terms.

Fix ffmpeg configuration when BR2_PACKAGE_FFMPEG_BSFS is not default ("all"):
Unknown option "--enable-bsfs=h264_metadata".
See ./configure --help for available options.
package/pkg-generic.mk:254: recipe for target '/root/buildroot/output/build/ffmpeg-4.2.2/.stamp_configured' failed
The option is named according to the scheme "--enable-SINGULAR=..." /
"--disable-PLURAL".
The typo is present since the release 2014.02:

With Microblaze Gcc version < 8.x the build hangs due to gcc bug
85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. To avoid
this problem, until now, ffmpeg could not be selected on
Microblaze. However, this problem only happens due to optimization,
and can worked around by forcing -O0.
So, when BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y, this commit:
- adds --disable-optimizations to FFMPEG_CONF_OPTS
- passes -O0 to CFLAGS in FFMPEG_CONF_ENV
Then, we remove 'depends on !BR2_microblaze' from Config.in to
re-enable the package.
Note that the comment was talking about gcc bug 71124, but this gcc
bug is a duplicate of 85180. Since all Buildroot packages now use the
reference to gcc bug 85180 and the option is named
BR2_TOOLCHAIN_HAS_GCC_BUG_85180, we use this naming as well for
ffmpeg.

The BR2_GCC_TARGET_* configuration variables are copied to
corresponding GCC_TARGET_* variables which may then be optionally
modified or overwritten by architecture specific makefiles.
All makefiles must use the new GCC_TARGET_* variables instead
of the BR2_GCC_TARGET_* versions.

ffmpeg always enables support for nvenc/cuda even if their support
libraries are not present:
External libraries providing hardware acceleration:
cuda cuvid nvenc
[...]
Enabled hwaccels:
h264_cuvid mjpeg_cuvid mpeg2_cuvid vc1_cuvid vp9_cuvid
hevc_cuvid mpeg1_cuvid mpeg4_cuvid vp8_cuvid
This leads to a crash in freeswitch git master when transcoding video
streams on a system without nvidia hardware:

2017-07-22 15:06:27.306760 [NOTICE] avcodec.c:828 NVENC HW CODEC ENABLED
This patch disables the support of nvidia hardware acceleration support
for now until the needed packages are added to buildroot. For details
