Done.

Couldn't you set this client in WebFrameClient and pass the WebFrame instead of
WebSecurityOrigin? According to your previous comment, you seem to want this to
be hooked to the WebView but it seems that it could be better in the WebFrame
given that you might want the lock to be in the browser context scope (ie. each
frame would have independant locks). Also, passing a WebFrame would give you
access to the WebSecurityOrigin and much more if needed.

+    virtual void requestWakeUnlock(WebWakeLockType, int requestId) = 0;
+
+    virtual void wakeLockDestroyed() = 0;
+    virtual void setRequestCallback(WebWakeLockRequestCallback*) = 0;

It's hard to review those without the WebWakeLockClient usage. Do you have a
link for the other CLs?

I'll send link to CL later.
