To inject custom renderers into SimpleExoPlayer, developers
currently need to extend SimpleExoPlayer and override the
renderer building methods. This is in contrast to the rest
of the library, where we use proper injection. This change
restores consistency. I think it's fine to make
SimpleExoPlayer final again, but if we find people extending
it for non-renderer purposes, we can revert that part of the
change.
ExoPlayerFactory now has analogous methods for the simple
and non-simple cases, which is a nice outcome.

When using a multi window time bar, the onScrubStop method uses another
method to estimate the seek position than the updateProgress method for
rendering the time bar. If the time line contains windows starting with an
ad period followed by other content, they differ in their behaviour.
- updateProgress checks all periods and leaves out all ad periods
- onScrubStop only checks windows and leaves them out when the first
period is an ad.
Changed onScrubStop to fit approach in updateProgess.

Fixes the following issues:
1. When a surface is set, it's expected that the renderer will
notify video size + when a frame is rendered to it. This is true
even if the surface isn't changing. Right now this is achieved
by setting renderedFirstFrame to false, but this is problematic
in the case that the surface isn't changing because (a) it will
force rendering of a subsequent frame to the output even when
paused, which is incorrect, and (b) isReady will return false
until this occurs.
2. When the surface really is changing, isReady can return false
until the first frame has been rendered into the new surface, which
will break seamless surface switching. This change allows isReady
to return true up to allowedJoiningTimeMs for this case.

Prior to this change, the only way to switch SimpleExoPlayerView
was to do:
oldView.setPlayer(null);
newView.setPlayer(player);
This would cause the video renderer to have to transition through
oldSurface->noSurface->newSurface, which is inefficient (noSurface
requires platform decoders to be fully released).
After this change we support:
newView.setPlayer(player);
oldView.setPlayer(null);
This results in direct oldSurface->newSurface transitions, which are
seamless on Android M and above. The change also adds some robustness
against developers ending up with strange behavior as a result of
clearing the player from a view in a different ordering than we expect
w.r.t. registering of other listeners.

If AudioTrack.setPlaybackParameters was called before initialization (for
example, when an audio renderer is enabled) the parameters would actually be
dropped, because configure calls reset, which didn't apply draining playback
parameters if the track was not initialized. It would then overwrite the
draining parameters with the current parameters.
Set the playback parameters directly (without draining) for uninitialized tracks
so that the call to setPlaybackParameters in configure is a no-op.
Also, reset the stored channel count and sample rate when the audio processor
is released so that configure returns true when it is next used, which makes
sure that it gets flushed.

The options to strip the subtitle of its styles were applied each time,

This additional computation (and memory allocations) can be prevented by

The idea of using reflection was so that a developer could
delete a package they didn't want and have everything else
still compile. However, a developer doing this is likely
building from source, in which case editing the factories
too is pretty trivial.
Removing the reflection makes specifying extractor flags
via the default factory easy, and removes the need for
special proguard config.

- Removed unnecessary null checks, code that was never executed,

- Add proper flushing of DvbParser, to prevent corrupt output
following a seek.
Only enable multi-window mode when the duration of every period in the timeline
is known. Also, remove the warning logged when there are too many windows as it
doesn't add much.
The player's current period index was not masked while there were
unacknowledged seeks. This led to the displayed position jumping, between when
seekTo was called (after which the position would be masked but not the period
index) and the seek being acknowledged (at which point the time bar's position
would jump back to the seek position, due to the period index being resolved).
Mask the period index, like the window index, to fix this behavior.

This change also ensures that format changes are read whilst the
renderer is enabled but without a codec. This is necessary to
ensure the drm session is updated (or replaced).
Updating the format is also needed so that the up-to-date format is
used in the case that the codec is initialized later due to the
surface being set. Previously, if an ABR change occurred between
the format being read and the surface being attached, we would
instantiate the codec and then immediately have to reconfigure it
when as a result of reading the up-to-date format. For a non-adaptive
codec this resulted in the codec being immediately released and
instantiated again!

Caption characters weren't being assigned to the correct window and the lack of
pen location support was causing multiple lines (and words) to be concatenated.
As per the CEA-708-B specification, section 8.10.5, when we encounter a DefineWindow
command, we're also supposed to update the current window to the newly defined one.
We were not doing this previously, resulting in text that should have been in separate
windows being combined into one. Furthermore, some content uses the SetPenLocation
command to move the cursor down a line instead of appending a new line. As we don't
currently support SetPenLocation, this resulted in multiple lines (and words) being
concatenated together, potentially causing the text to extend past the edge of the
window/screen. This change implements a workaround (until SetPenLocation is properly
supported) for this issue in which setting the pen location to a new row will append
a new-line to that window.

- Fix to use different track ids for EMSG + CEA608, so they can
both be enabled at once.

parsing the initial moov box. This makes it easier to handle
multiple tracks through the chunk package. It may or may not
be made a requirement (it's already true for the MKV extractor).

pixel counts) then use bitrate as a tie breaker instead. Also
use pixel count as a tie breaker if pixel counts are known
but equal. Streams with known pixel counts will always be
preferred over streams without.
