Rename classes with "Extensions" in name.

We have moved away from the idea that you can only replace objects with the word Extensions in the file name.

VideoModelExtensions can be removed and method move do VideoModel.

Hello all. With 2.0 we have changed how you extend objects and the idea of marking a class with the name extension does not make much sense anymore. So I propose the following file name changes to happen before we release. Please take some time to review the changes and let me know ASAP if you have issue or suggestions with any of the changes. Very open minded to the name and location just want to get the extensions out of name and removed that folder. There a couple other moves to and from utils that seems to make sense to do now as well.

streaming/extensions:
extensions/MediaSourceExtensions.js ----> controllers/MediaSourceController.js
extensions/RequestModifierExtensions.js ----> utils/RequestModifier.js
extensions/SourceBufferExtensions.js ----> streaming/SourceBuffer.js
extensions/TextTrackExtensions.js ----> streaming/TextTracks.js
extensions/VideoModelExtensions.js ----> one method will be merged into VideoModel and entire class will be deleted.

streaming/utils:
utils/VirtualBuffer.js ----> streaming/VirtualBuffer.js

dash/extensions:
extensions/BaseURLExtensions.js ----> dash/BaseURLLoader.js OR controllers/BaseURLContorller.js
extensions/DashManifestExtensions.js ----> dash/DashManifest.js
extensions/DashMetricsExtensions.js ----> dash/DashMetrics.js
extensions/FragmentExtensions.js ----> dash/utils/FragmentedTextUtil.js

dash ---> dash/util:
dash/TimelineConverter.js ----> dash/utils/TimelineConverter.js

protection:
protection/ProtectionExtensions.js ---> ProtectionKeyController.js or merge into protection controller. The latter being a big change near a release.

I think renaming SourceBufferExtensions to SourceBuffer could cause confusion - to make SourceBufferController makes more sense, as it creates and manipulates SourceBuffers.

I think BaseURLLoader or BaseURLController are misleading. SegmentBaseLoader/Controller?

I think both suggestions are good and I will use over my original names. Thanks guys.
