The detailed security advisories can be found at:

  https://webkitgtk.org/security/WSA-2019-0003.html

The BR2_PACKAGE_WEBKITGTK_ARCH_SUPPORTS_JIT configuration symbol is not
needed anymore, because the logic to decide whether the JavaScriptCore
JIT spport can be enabled has been improved upstream.

One of the new features in 2.24.x is the support for JPEG2000 images,
which is implemented using the OpenJPEG library. Therefore now
BR2_PACKAGE_OPENJPEG is selected.

This adds one small patch which did not make it to the 2.24.2 release
which solves a build issue when the building the GStreamer GL elements
is disabled.
