Hi Anton, Mounir and Philip!

While still rough, you may want to take a look at the overall
structure now. Should hopefully be a bit closer to what's been
discussed (some naming issues left though).

MediaSession has now acquired a session_id and multiple of them can be
alive at the same time within a WebContents.

BrowserMediaPlayerManager now goes through the
BrowserMediaSessionManager to control players as members of sessions,
instead of going directly at the default media session.

WebMediaPlayerAndroid has a session_id for which session it should
belong to.

One possibly important thing about media players having a
(media-)session_id: it's the session they'd like to be part of
(roughly matching <element>.session = session).

That's not the same as the other way around - sessions having
player_id. This is closer to what the spec calls a participating audio
producing object and a player may jump in and out of a session as it's
being played and stopped but the player always has the same
session_id.

Have you had a chance of looking at the general direction here?

The design looks closer to what I was hoping for. I disagree on some details but
it's probably good enough for you to start splitting the CL and send reviews.

On my side, I'm going to apply this locally and write some stuff on top of it.

Re-opening. Will serve as a stash for experimental media session stuff a while
longer.
