Rebuild for dav1d 1.5.0

... in order to make it possible for us to update openh264 without
having to recompile ffmpeg against the new version every time. As
openh264 is distributed by Cisco and ffmpeg is in Fedora, it's difficult
to coordinate lock step updates. Drop the version check to make this
easier.

https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=10211

This also rebases downstream ffmpeg-dlopen-openh264.patch on top of
the new patch.

+From a641e629591d68bd3edd99bddec623dc31295f6b Mon Sep 17 00:00:00 2001
+From: Kalev Lember <klember@redhat.com>

+Subject: [PATCH] lavc/libopenh264: Drop openh264 runtime version checks
+
+Years ago, openh264 releases often changed their ABI without changing
+the library soname. To avoid running into ABI issues, a version check
+was added to lavc libopenh264 code to error out at runtime in case the
+build time and runtime openh264 versions don't match.
+
+This should no longer be an issue with newer openh264 releases and we
+can drop the runtime version check and rely on upstream doing the right
+thing and bump the library soname if the ABI changes, similar to how
+other libraries are consumed in ffmpeg.
+
+Almost all major distributions now include openh264 and this means there
+are more eyes on ABI changes and issues are discovered and reported
+quickly. See e.g. https://github.com/cisco/openh264/issues/3564 where an
+ABI issue was quickly discovered and fixed.
+
+Relaxing the check allows downstream distributions to build ffmpeg
+against e.g. openh264 2.3.1 and ship an update to ABI-compatible
+openh264 2.4.0, without needing to coordinate a lock step update between
+ffmpeg and openh264 (which can be difficult if openh264 is distributed
+by Cisco and ffmpeg comes from the distro, such as is the case for
+Fedora).

+Subject: [PATCH] avcodec/openh264: Add the ability to dlopen() OpenH264
+
+We can't directly depend on OpenH264, but we can weakly link to it
+and gracefully expose the capability.
