Log Message

Make C API more robust against null contexts
https://bugs.webkit.org/show_bug.cgi?id=116462

Reviewed by Anders Carlsson.

Handle null contexts in a non-crashy way.  It's a bug to ever call the
API with a null context, and the absence of a context means we can't
produce a meaningful result, so we still assert in debug builds.

Now where possible we detect and early return, returning null for any
pointer type, NaN for doubles, and false for any boolean result.

+        Handle null contexts in a non-crashy way.  It's a bug to ever call the
+        API with a null context, and the absence of a context means we can't
+        produce a meaningful result, so we still assert in debug builds.
+
+        Now where possible we detect and early return, returning null for any
+        pointer type, NaN for doubles, and false for any boolean result.
