Introducing ClassMap to represent a class collection.

This CL introduces a new abstraction ClassMap to represent
a collection of classes of a particular kind which supports
lazy loading and various class sources/providers.

Key changes:

** ResourceProvider renamed into ClassFileResourceProvider
   since DEX resource apparently does not fit very well into
   ResourceProvider API.

** ClassProvider interface is introduced to unify the way
   ClassMap gets its classes populated.

** Raw class maps are hidden behind ClassMap abstraction.
   Three separate class collection types are created to
   represent program, classpath and library collections.

** Program classes are always considered preloaded, but they are
   still represented by ProgramClassCollection rather than bare map.

** Some of the classes are still pre-loaded by ApplicationReader
   and are submitted into collections by using special ClassProvider
   for preloaded classes. This works for DEX files and resources
   submitted NOT via resource providers. We might improve this later.
