Update master test file.

Revert accidentally-committed changes.

PARB changes: Refactor MediaFactory and Loader classes:
- MediaInfo becomes MediaFactoryItem. All MediaFactory and plugin-related APIs are updated accordingly. The rule of thumb is to use "item" on MediaFactory, and "mediaFactoryItem" on the plugin classes (since the former are already qualified, whereas the latter are not).
- Remove IMediaResourceHandler. Add canHandleResource to LoaderBase. Make handler function a Function to pass to MediaFactoryItem's constructor.
- Merge resolver interfaces/classes into MediaFactoryItemResolver, which defaults to selecting the first one.
- Make LoaderBase load/unload methods final. Add protected methods to execute the load, so that we can ensure validation takes place first.
- Update all unit tests and sample apps accordingly.

1. Fix a bug that deals with discontinuity of fragments. This is the first check in of the fix. More extensive testings may discover other issues.
2. Apply a patch from Matthew, quoted from Matthew's email:
This one should pick up “play now can take a starting offset”, stubs out “play for duration”, and also picks up “data messages are lost during enhanced seek”.
