   libaom: Update to 3.3.0

   2022-01-28 v3.3.0
     This release includes compression efficiency and perceptual quality
     improvements, speedup and memory optimizations, some new features, and
     several bug fixes.

     - New Features
       * AV1 RT: Introducing CDEF search level 5
       * Changed real time speed 4 to behave the same as real time speed 5
       * Add --deltaq-strength
       * rtc: Allow scene-change and overshoot detection for svc
       * rtc: Intra-only frame for svc
       * AV1 RT: Option 2 for codec control AV1E_SET_ENABLE_CDEF to disable
         CDEF on non-ref frames
       * New codec controls AV1E_SET_LOOPFILTER_CONTROL and
         AOME_GET_LOOPFILTER_LEVEL
       * Improvements to three pass encoding

     - Compression Efficiency Improvements
       * Overall compression gains: 0.6%

     - Perceptual Quality Improvements
       * Improves the perceptual quality of high QP encoding for delta-q mode 4
       * Auto select noise synthesis level for all intra

     - Speedup and Memory Optimizations
       * Added many SSE2 optimizations.
       * Good quality 2-pass encoder speedups:
         o Speed 2: 9%
         o Speed 3: 12.5%
         o Speed 4: 8%
         o Speed 5: 3%
         o Speed 6: 4%
       * Real time mode encoder speedups:
         o Speed 5: 2.6% BDRate gain, 4% speedup
         o Speed 6: 3.5% BDRate gain, 4% speedup
         o Speed 9: 1% BDRate gain, 3% speedup
         o Speed 10: 3% BDRate gain, neutral speedup
       * All intra encoding speedups (AVIF):
         o Single thread - speed 6: 8%
         o Single thread - speed 9: 15%
         o Multi thread(8) - speed 6: 14%
         o Multi thread(8) - speed 9: 34%

     - Bug Fixes
       * Issue 3163: Segmentation fault when using --enable-keyframe-filtering=2
       * Issue 2436: Integer overflow in av1_warp_affine_c()
       * Issue 3226: armv7 build failure due to gcc-11
       * Issue 3195: Bug report on libaom (AddressSanitizer: heap-buffer-overflow)
       * Issue 3191: Bug report on libaom (AddressSanitizer: SEGV on unknown
         address)
       * Issue 3176: Some SSE2/SADx4AvgTest.* tests fail on Windows
       * Issue 3175: Some SSE2/SADSkipTest.* tests fail on Windows
