Introduce PersistableBundle

The PersistableBundle class is similar to Bundle except that only
objects that have meaning across reboots can be stored and there
is a limited number of types that can be stored. More
specifically Binders, FileDescriptors, Parcelables, Booleans,
Bytes, Shorts, Chars, CharSequences, Floats, and ArrayLists
cannot be stored.

Fixes bug 13736007.
