SKIPPED can't be handled as CONTENT_RESUME_REQUESTED because after skipping an
ad there may be further ads to play in its ad group.
Remove workaround for handling unexpected playAd without stopAd, as the player
can instead recover when IMA sends CONTENT_RESUME_REQUESTED. This in turn fixes
handling of the case where playAd is called twice but IMA expects only the
first ad to play, when skipping a particular ad. (Add an ad tag where this
occurs to internal samples.)
Check whether a currently playing ad has been marked as played in
ExoPlayerImplInternal, and handle this case as a seek. This ensures that any
loaded ad periods are discarded in the case of CONTENT_RESUME_REQUESTED.

Store playWhenReady when playAd is called, and restore it if necessary when the
content resumes.

Remove assertions in pauseAd()/playAd(), which can fail if events are delivered
after detaching the player, and log warnings instead.
Use whether IMA has sent CONTENT_PAUSE_REQUESTED/CONTENT_RESUME_REQUESTED to
determine whether we pause/resume the AdsManager, matching the IMA
documentation.
Also clean up use of player.isPlayingAd vs playingAd.

adsLoader.contentComplete was called twice which led to postrolls not seeing
the STARTED event.
Also make the onPositionDiscontinuity handler easier to follow by renaming
variables, and remove the adGroupIndex field.

Once background and resuming is supported, the ads loader will be kept when the
player is destroyed and recreated. Move the state relating to the structure of
ads and what ads have been loaded/played out of the media source and into the
loader so the information is not lost when the source is released, in
preparation for supporting background and resuming.

This also adds support for seeking in periods with midroll ads.

This will allow MediaSources to provide MediaPeriods that correspond to ad
breaks in a timeline period rather than content for a timeline period, in a
future change.

continueLoading may be called during preparation, but this is not
handled correctly in the case where a deferred period doesn't
have a source yet.
