When a static library A references static library B,
and app C references both A and B, we get the following symbol merging,
symbols from library B get imported twice.
We must only check that symbol references to library B are valid
when building library A. We should only merge all the symbols
when building final app C.

Previously, you could only reference namespace prefixes in attribute names:
<View xmlns:appcompat="http://schemas.android.com/apk/res/android.support.v7.appcompat"
appcompat:name="hey"
...
Now you can also reference them in resource names within an attribute value:
...
android:text="@appcompat:string/confirm"
...
Which will be treated as "@android.support.v7.appcompat:string/confirm".
