libcef, and also adds a few changes picked from our previous
implementation that enables the applications to communicate with the
agl-compositor.

+Subject: [PATCH 3/9] Remove the GN settings done for clang that conflict with
+ OE
+
+clang cross compiler that is build with meta-clang has lot of these
+settings built-in and specifying them here confuses the compiler
+
+--target option and -no-canonical-prefixes options result in clang
+
+finding the headers in target sysroot
+
+Upstream-Status: Inappropriate [OE-Specific]
