Don't re-parse the framework resources all the time.

A small optimization to the resource code, to not re-parse the framework
resources every time we build a new AssetManager.  Instead, you can now
construct a ResTable from a previously created one...  of course, like the
existing code for using the data in-place, you can't delete the original
ResTable until you have deleted the one that has been constructed from it.
