qt5-qtwebengine/qtwebengine-opensource-src-5.9.0-openmax-dl-neon.patch
Kevin Kofler c87d486b00 Update to 5.9.0
* Sat Jun 10 2017 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.9.0-1
- Update to 5.9.0
- Update version numbers of bundled stuff
- Use bundled libsrtp and protobuf, Chromium dropped unbundling support for them
- Add missing Provides: bundled(hunspell) for the spellchecking added in 5.8
- Rebase linux-pri, no-neon, system-icu-utf, no-sse2, arm-fpu-fix,
  openmax-dl-neon and webrtc-neon-detect patches (port to GN)
- Sync system-nspr-prtime patch with Debian (they ported it to GN)
- Rebase fix-extractcflag patch
- Restore NEON runtime detection in Skia, drop old skia-neon patch (rewritten)
- Drop webrtc-neon, v8-gcc7, pdfium-gcc7, wtf-gcc7, fix-open-in-new-tab and
  fix-dead-keys patches, fixed upstream
- Update system libvpx/libwebp version requirements (libvpx now F25+ only)
- Drop the flag hacks (-g1 -fno-delete-null-pointer-checks) that are fixed
  upstream, force -g2 on x86_64 instead
