(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

accumulated thousands of these already, and it's not immediately

* Whose namespace is the HTML namespace and whose qualified name
is qualifiedName, in ASCII lowercase.
* Whose namespace is not the HTML namespace and whose qualified
name is qualifiedName.
This patch adds an IPC call for debugging requests. It's stringly typed
and very simple, and allows us to easily implement all the features in
the Browser's Debug menu.
