Moving ControlBarPluginSample and Test into the plug-ins folder.

PARB feedback: taking out 'media' references; renaming measureMedia to measure, and updateMediaDisplay to layout.

PARB feedback: updating sample to use measureWidth and height.

PARB feedback: renaming LayoutRenderer.targets to hasTarget.

PARB feedback: adding ASDocs to LayoutRenderer.measuredWidth and height properties.

PARB feedback: change mediaWidth and mediaHeight properties on layout renderer related classes to measuredWidth, and measuredHeight.

PARB feedback: change LayoutRenderer.context to container, and making adding a @private tag to the subclass stubs' ASDocs.

Removing lingering import, and adding copyright header.

Phase 2 of the MBR refactoring. Implement play2 on HTTPNetStream. Necessitated modifying the index handler to expose the stream names via a notify event (though this approach may change). Isolate HTTP setup code to HTTPStreamingNetLoader. Refactor NetStreamPlayTrait to be completely agnostic to NetStream type. Merge NetStreamDynamicStreamTrait and HTTPStreamingNetStreamDynamicStreamTrait. Introduce temporary loaded context for F4MElement to avoid RTEs.

The end result is that RTMP and HTTP stream switching now use the NetStreamSwitchingManager, rather than RTMP using the former and HTTP using internal switching logic. Still need to determine whether to remove HTTPNetStream's switching logic, or keep there for other use cases. Note that we still need to extract HTTPNetStream's switching logic into one or more switching rules (that's phase 3, still to come). Doing so might involve modifying the MetricsProvider to take into account any variations in metrics between RTMP and HTTP.

Initial commit of refactored MBR logic. Separate MBR switching management from NetStream, so that it could work with any arbitrary NetStream (such as HTTPNetStream, although that hasn't been integrated yet). Update NetMocker and unit tests accordingly.
