<pre>[media-source] Support MediaSource.setLiveSeekableRanges()
https://bugs.webkit.org/show_bug.cgi?id=162252

Source/WebCore:
Fixes tests: imported/w3c/web-platform-tests/media-source/interfaces.html
imported/w3c/web-platform-tests/media-source/mediasource-liveseekable.html
Add support for a new part of the Media Source specification, the ability for clients to
specify the seekable ranges for a MediaSource-backed HTMLMediaElement.
Adding the live-seekable methods to MediaSource fixes a large number of the interfaces.html
tests, and the rest are fixed by adding on<event> handlers to MediaSource, SourceBuffer,
and SourceBufferList.

+ [media-source] Support MediaSource.setLiveSeekableRanges()
+ https://bugs.webkit.org/show_bug.cgi?id=162252
+
+ Reviewed by Sam Weinig.
+
+ Fixes tests: imported/w3c/web-platform-tests/media-source/interfaces.html
+ imported/w3c/web-platform-tests/media-source/mediasource-liveseekable.html
+
+ Add support for a new part of the Media Source specification, the ability for clients to
+ specify the seekable ranges for a MediaSource-backed HTMLMediaElement.
+
+ Adding the live-seekable methods to MediaSource fixes a large number of the interfaces.html
+ tests, and the rest are fixed by adding on<event> handlers to MediaSource, SourceBuffer,
+ and SourceBufferList.
