contrib: aom: update to v3.15.0

Release v3.15.0 Quibble Pants

2026-08-25 v3.15.0
  This release is ABI compatible with the last release.

  This release includes the fixes for all the security issues found by
  AI tools recently.

  Important build system change: The cmake option ENABLE_APPS was added
  to build aomdec and aomenc without building the example programs. The
  cmake option ENABLE_EXAMPLES was redefined to build only the example
  programs.

  - New Features
    * Test only: New codec control AV1E_SET_MODE_REF_DELTA_ENABLED for
      the encoder to toggle loopfilter mode_ref_delta_enabled.
    * New codec option “force-max-q” for the encoder to force the use
      of max Q in VBR mode.
    * Completed low-complexity decode mode development for VOD video,
      and supported HDres (i.e. 720p to 1080p) encoding.
    * IntraBC for RTC screen: improvements to allow and speed up this
      tool for realtime mode.

  - Compression Efficiency Improvements
    * Improved the rate allocation among hierarchical layers and luma
      and chroma planes.

  - Perceptual Quality Improvements
    * Improved VMAF metric while maintaining PSNR performance.

  - Speedups
    * Continued the speed 0 to 3 encoder speed optimizations.
    * Improvements to Arm optimizations for convolve and variance
      functions.

  - Bug Fixes
    * Bug 541725398: aom_img_flip: fix chroma height calculation
    * Bug 437872594: CONFIG_SHARED=1 produces an .a(rchive) file for
      static linking
    * Bug 503326506: SEGV in encoder_destroy via failed encoder
      initialization
    * Bug 538651949: Bounds-check bypass in AV1E_SET_SVC_LAYER_ID:
      ppi/svc layer-count desync re-enables OOB layer_context[]
      read/write (incomplete fix for issue 503993985 / CVE-2026-56209)
    * Bug 525452409: The math and Threads::Threads library dependencies
      should not be part of the link interface of the aom shared library
    * Bug 524353636: AOM_EXTRA_C_FLAGS/-DSANITIZE= flags not propagated
      w/CMAKE_BUILD_TYPE=Debug
    * Bug 513342555: Potential heap double-free in libaom AV1 MT
      encoding via aliased macroblock data
    * Bug 520656240: Copy on write: libaom AV1 wedge/interintra mask
      buffers could be precomputed
    * Bug 514696186: aomdec fails with "Failed to decode tile data" on
      stream encoded by aomenc
    * Bug 382465458: Chessboard pattern on flat gray video encoded with
      libaom AV1
    * oss-fuzz:514006304: Increase ctx->cx_data_sz to 2.5x uncomp frame
      size
    * Bug 514816767: aomenc fails assertion check mi->bsize == bsize
    * Bug 504613867: Potential heap OOB read in
      av1_int_pro_motion_estimation due to stale stride (CVE-2026-13906)
    * Bug 503810640: Undefined behavior: NaN-to-int conversion in
      aom_noise_model_get_grain_parameters
    * Bug 503171639: Heap-buffer-overflow in
      av1_update_and_record_txb_context via SVC encoding with mismatched
      TXB buffer size
    * Bug 505976409: SIGFPE (integer divide-by-zero) in libaom AV1 SVC
      encoder
