Refactor how the storage is used.

This is the initial refactoring to improve how we deal with the storage.

It does a couple of things:
* Rename Sink::Storage to Sink::Storage::DataStore to free up the
  Sink::Storage namespace
* Introduce a Sink::ResourceContext to have a single object that can be
  passed around containing everything that is necessary to operate on a
  resource. This is a lot better than the multiple separate parameters
  that we used to pass around all over the place, while still allowing
  for dependency injection for tests.
* Tie storage access together using the new EntityStore that directly
  works with ApplicationDomainTypes. This gives us a central place where
  main storage, indexes and buffer adaptors are tied together, which
  will also give us a place to implement external indexes, such as a
  fulltextindex using xapian.
* Use ApplicationDomainTypes as the default way to pass around entities.
  Instead of using various ways to pass around entities (buffers,
  buffer adaptors, ApplicationDomainTypes), only use a single way.
  The old approach was confusing, and was only done as:
  * optimization; really shouldn't be necessary and otherwise I'm sure
  we can find better ways to optimize ApplicationDomainType itself.
  * a way to account for entities that have multiple buffers, a concept
  that I no longer deem relevant.

While this commit does the bulk of the work to get there, the following
commits will refactor more stuff to get things back to normal.
