Start throwing better exceptions in LayoutInflater.

Include source layout file in exceptions thrown from
LayoutInflater. This makes it easier to trace failures
when using <include ...> tags.

You'll get something like
Caused by: android.view.InflateException: Binary XML file line #11 in com.myapp:layout/activity_main: Binary XML file line #6 in com.myapp:layout/overlay: Error inflating class MyView
Caused by: android.view.InflateException: Binary XML file line #6 in com.myapp:layout/overlay: Error inflating class MyView
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.myapp.MyView"...
