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()
