MSE: Experimental support for customizing live seekable range

Adds {set,clear}LiveSeekableRange methods to MediaSource IDL, with
implementations corresponding to the recent MSE spec addition of these
methods [1]. These methods are behind the MediaSourceExperimental
RuntimeEnabled flag until intent to ship is approved in a later
milestone.
Intent to implement thread is at [2].

The CQ bit was checked by wolenetz@chromium.org to run a CQ dry run

[wolenetz, 2016-06-28 01:03:31]

Please take a look:
chcunningham@: everything (as MSE owner)
mlamouri@: everything from Blink perspective (things like Member, trace, etc).

Note that there is going to be a layout test imported for this from
w3c/web-platform-tests once https://github.com/w3c/web-platform-tests/pull/3184
lands and bulk import from w3c includes MSE. I checked and the current version
of that test in that PR passes with this CL applied (using our layout test
runner which includes experimental-web-platform-features, which includes
MediaSourceExperimental). I didn't include that test here since it was authored
by a w3c resource directly into w-p-t.

Thanks!

(it's missing tests but I see there are some in WPT and that's super great! :))

:))

Yeah, I ran this against that wpt test (adjusting the /resources/... script
links to /w3c/resources/...) and it passed. To eliminate redundancy, plan is to
just import that WPT test soon.

I've filed crbug.com/624037 to track making sure that test coverage gets into
Blink somehow soon.

Thanks for reviews. There's 1 lg*m on the intent to implement, so I'll land this
soon (win_chromium_rel_ng bot appears to be having a bit of problems unrelated
to this CL...)
