Removed non-rtm providers
Code in CreateTableHandler.AddOperation compares AddForeignKeyOperation instances but ModelDiffer creates new instances
so the comparison always fails. The first thought was to compare FK names instead but the option coded here should be better.
The change adds the FK operations referenced by CreateTableOperation to the operation collection instead of creating new ones.

- Added Attach
- Removed async methods except for Add
- Added non-generic overloads on DbContext
- Removed XxxRange methods and added params overloads
- Changed return types to EntityEntry--see Issue #498

This is part of Issue #193
Use TryAdd in AddXxx methods to only add services if not already present.

Issue #956 and also see pull request #1129.

This change updates all of our AddXxx methods to use TryAdd when adding to the service collection such that only services that are not already registered will be registered. This also means that the code we had to check the service collection for "hosting" services is no longer needed.

Note that services for which it is expected that multiple instances can be registered (e.g. listeners and data sources) must not use TryAdd since otherwise only the first registered will be used.
