- build internal ffmpeg to avoid dependency on system one (we have dropped restricted in rosa2021.1 and have merged it into main and contrib)
- clean up build dependencies a bit (more clean up is required)
- remove not used if-else and patches
- drop patches for VA-API, upstream has VA-API support now, it is enabled, it is enough, I am fed up with different patches here
- drop patch for scripts generating installtion packages which are not used by us
- rename master_prefenrecnes to master_prefenrences.json to make "abf put" not upload it to filestore.
- cherry-pick upstream fixes for statx() in new glibc
- switch to internal libsecret backend instead of the no more maintained gnome-keyring
https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1828192
libsecret should handle passwords previously saved via gnome-keyring
- use system fontconfig and freetype (maybe it will help to make fonts better, maybe not, but there is no sense in using bundled ones), use system libdrm
- remove odd metadata in new platforms
- enable Vulkan (RB#11463), keleg@ noted disabled Vulkan in chrome://gpu despite hardware supporting it
https://bugzilla.rosalinux.ru/show_bug.cgi?id=11463
- disable Control Flow Integrity (is_cfi) to avoid depending on too new clang, CFI amkes no sense for us
- install crashpad_handler (chromium tries to execve() it)
