Bug 29634

Hi

I just built chromium-95.0.4638.69 for MGA8, using clang and removing the need to use python2 (python 3 only then).

I used our MGA8 spec file as a base, I tested it and the src.rpm is available.

I moved to clang because using gcc leads to quite some work to patch the code and the chromium teams doesn't provide any support: https://bugs.chromium.org/p/chromium/issues/detail?id=1263993
Then, it was required to manage that Chromium has moved to clang13 and MGA8 still uses clang11.

As python2 is not supported by Mageia anymore and as Chromium fully supports python3, I thought it would be a good idea to do the switch now.

Changes made:
* chromium-browser-stable.spec: of course, updated with the new patches and additional adjustments for python3, clang and deprecated part of the source. -> chromium-browser-stable-spec.patch

* chromium-compiler-r4.patch -> chromium-95-compiler-r4.patch, 
**to accommodate code change.

* chromium-norar.patch -> chromium-95_69-norar.patch 
**same purpose but to handle code changes and to remove rar_analyzer as a dep for safe_browsing.

* chromium-55-extra-media.patch -> chromium-95-extra-media.patch
  chromium-40-wmvflvmpg.patch -> chromium-95-wmvflvmpg.patch
  chromium-40-sorenson-spark.patch -> chromium-95-sorenson-spark.patch
  chromium-extra-media-video-profiles.patch -> chromium-95-extra-media-video-profiles.patch
**to handle code changes some parts have been reworked and removed from original patches, to be added into chromium-95-extra-media.patch instead

* chromium-45-no-external-components.patch -> chromium-95-no-external-components.patch
**same purpose but to handle code changes

* chromium-77-python2.patch -> deprecated moving to python3

* chromium-gcc-includes.patch -> chromium-95-gcc-includes.patch
  chromium-gcc-type-errors.patch -> chromium-95-gcc-type-errors.patch
**removed applied patches 

* chromium-gcc-character-literals.patch -> chromium-95-gcc-character-literals.patch
  chromium-gcc-anonymous-namespace.patch -> chromium-95-gcc-anonymous-namespace.patch
  chromium-gcc-unsorted.patch -> chromium-95-gcc-unsorted.patch
  chromium-gcc-disabled-warnings.patch -> chromium-95-gcc-disabled-warnings.patch
  chromium-gcc-braces.patch -> chromium-95-gcc-braces.patch
**same purpose but to handle code changes

* chromium-95-system-zlib.patch -> additional fix build with system zlib for Chromium 95
**new patch

* chromium-89-EnumTable-crash.patch -> removed as it leads to enum_table.h:359:18: error: no template named 'vector' in namespace 'std' (because of 95 version or because of clang 13?)

* chromium-95-clang_compiler.patch
  chromium-clang-nomerge.patch
**new patches to use clang11 instead of clang13 (unknown option -ffile-compilation-dir), from opensuse.

* chromium-95-maldoca-zlib.patch
**new patch from Arch. Fix system zlib_common_header error with maldoca

* chromium-95-BitstreamReader-namespace.patch
** new patch from Chromium "upstream"

Nicolas, I cc you as you are the mentor. 

Let me know what else I could do.
