for what changes are needed, and sed commands that can be used to make them en masse.
I've verified that bitbake -c patch world works with these, but did not run a world
build; the majority of recipes shouldn't need further fixups, but if there are
some that still fall out, they can be fixed in followups.

Changes for 1.5.1 'Sonic':
--------------------------
1.5.1 is a minor release of dav1d, focusing on optimizations and stack reduction:
- Rewrite of the looprestoration (SGR, wiener) to reduce stack usage
- Rewrite of {put,prep}_scaled functions
Now, the required stack space for dav1d should be: 62 KB on x86_64 and
58KB on arm and aarch64.
- Improvements on the SSSE3 SGR
- Improvements on ARM32/ARM64 looprestoration optimizations
- RISC-V: blend optimizations for high bitdepth
- Power9: blend optimizations for 8bpc
- Port RISC-V to POSIX/non-Linux OS
- AArch64: Add Neon implementation of load_tmvs
- Fix a rare, but possible deadlock, in flush()

Changes for 1.5.0 'Sonic':
--------------------------
1.5.0 is a major release of dav1d, that:
- WARNING: we removed some of the SSE2 optimizations, so if you care about
systems without SSSE3, you should be careful when updating!
- Add Arm OpenBSD run-time CPU feature
- Optimize index offset calculations for decode_coefs
- picture: copy HDR10+ and T35 metadata only to visible frames
- SSSE3 new optimizations for 6-tap (8bit and hbd)
- AArch64/SVE: Add HBD subpel filters using 128-bit SVE2
- AArch64: Add USMMLA implempentation for 6-tap H/HV
- AArch64: Optimize Armv8.0 NEON for HBD horizontal filters and 6-tap filters
- Power9: Optimized ITX till 16x4.
- Loongarch: numerous optimizations
- RISC-V optimizations for pal, cdef_filter, ipred, mc_blend, mc_bdir, itx
- Allow playing videos in full-screen mode in dav1dplay
