When an ExtractorMediaSource is used in a concatenation, and
probably when using repeat modes, it needs to produce multiple
ExtractorMediaPeriods during usage. Currently we fire a
source info refresh every time a new ExtractorMediaPeriod
instance prepares, which triggers ExoPlayer.EventListener's
onTimelineChanged method. In nearly all cases the timeline is
unchanged after the first ExtractorMediaPeriod is prepared.
This change suppresses these no-op changes.

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.

When resetting a SampleQueue, by default the upstream format
is not cleared. This is necessary for progressive playbacks,
since (a) the formats never change, and (b) the extractors
only output them once. So when a seek occurs, it's necessary
to clear all sample data from the queue, but retain the current
upstream format.

Uniquely for HLS, the media in a SampleQueue that we may read
from can be in a format not supported by the consuming renderers.
We clear all the sample data from the queue in this case, but
not the upstream format. Since we have an optimization that
allows the upstream format to be read in advance of another
sample being written into the queue, this can result in an
unsupported format being read by a consuming renderer. This
change ensures the upstream format is correctly cleared in the
problematic case.

All implementations of SequenceableLoader already implement this method.
Moreover, all composite media periods contained an exact copy of an
implementation that now moved to CompositeSequencableLoader.

Currently the renderer is only ready when the input stream has more data to
read. Actual renderers, however, are also ready as long as their output buffer
contains some audio/video samples to play, roughly corresponding to the fact
that the playback time hasn't reached the timestamp of the last buffered
sample. Added a isready flag to FakeRenderer to simulate this behaviour.

This is possible to do without passing the player instance to
custom action providers through their constructors, given we
no longer have a MuteActionProvider. Passing the player through
the constructors generalizes better to such cases, however, so
feels like the right thing to do.

It's also possible to use generics and keep passing the player
instance via the CustomActionProvider methods, but this adds
some unnecessary complexity.

Extensions can perform additional actions whenever data is read (e.g. sleeping
to simulate bandwidth restrictions).

Additionally, the factory class can also be overwritten and allows to set the
FakeDataSet later in case it is not available right away.

Moreover, this class now also uses a transfer listener similar to all real data sources.

We currently read at most 5 packets at a time from the
extractor input. Whether this is inefficient depends on
how efficiently the underlying DataSource handles lots
of small reads. It seems likely, however, that DataSource
implementations will in general more efficiently handle
fewer larger reads, and in the case of this extractor
it's trivial to do this.

Notes:
- The change appears to make little difference in my
  testing with DefaultHttpDataSource, although analysis
  in #3040 suggests that it does help.
- This change shouldn't have any negative implications
  (i.e. at worst it should be neutral wrt performance). In
  particular it should not make buffering any more likely,
  because the underlying DataSource should return fewer
  bytes than are being requested in the case that it
  cannot fully satisfy the requested amount.

If seek is called for a non-seekable period, when the period is prepared the
start position will be updated from the seek position to zero. Because the
start position is part of the renderer offset for the first loaded period
holder, after the update the renderer offset start position and the new start
position would no longer cancel out, leading to the player position being
negative.

The first period holder's renderer offset is the fixed base offset (60 seconds)
plus its start position, but the start position is always subtracted. Avoid
subtracting the start position for the first period holder so that when it
changes there is no need to update the renderer offset.

drmInitData can be null in DASH if all of the init data is
specified at the manifest level instead. I took a look at
injecting the manifest format into the extractors, so that
we can actually copy the scheme type into it, but that's
at least non-trivial enough to delay for a subsequent CL.

We'd normally expect playback controls to be hidden during
ad playback, although if they are visible for whatever reason,
it makes sense to set the position to the current content
position now that we have it.

"Default (none)" is sometimes just wrong, since the track
selector may attempt to select a track even if it exceeds
the renderer's capabilities. Just "Default", as it used to
be, was more accurate.
