1. Only output video starting from a keyframe
2. When calculating the timestamp offset to adjust live streams to start
at t=0, use the timestamp of the first tag from which a sample is actually
output, rather than just the first audio/video tag. The test streams in
the referenced GitHub issue start with a video tag whose packet type is
AVC_PACKET_TYPE_SEQUENCE_HEADER (i.e. does not contain a sample) and whose
timestamp is set to 0 (i.e. isn't set). The timestamp is set correctly on
tags that from which a sample is actually output.

We currently don't display the last frame because the seek time is behind the
last frame's timestamps and it's thus marked as decodeOnly.
This case can be detected by checking whether all data sent to the codec is
marked as decodeOnly at the time we read the end of stream signal. If so, we
can re-enable the last frame. This should work for almost all cases because the
end-of-stream signal is read in the same feedInputBuffer loop as the last
frame and we therefore haven't released the last frame buffer yet.

We are currently queuing periods in a way such that the new start position
lines up with the end of the previous period (to ensure continuous playback).
However, if the start position of the new period is larger than the total of
all previously played period durations, we may end up with negative renderer
timestamps when seeking back to the beginning of this new period. Negative
timestamps should be avoided as most decoders have problems handling them
correctly.
This change forces a renderer reset if we detect such a seek to a negative
renderer time and also resets the renderer offset to 0 every time all
renderers are disabled, as this is the only time where we can savely change
the offset of an existing media period.
Also, if playback starts with an ad, we choose the content position as
renderer offset to prevent the whole issue from occurring for the seek-behind-
midroll case.

In some edge cases the renderer position may be slightly ahead of the
buffered position and the total buffered duration is thus negative. We already
filter that in ExoPlayerImpl for the publicly accessible value. However, we
forward the unfiltered value to other components like the LoadControl, which
may be confusing.

This permission has normal access right and can't be revoked by the user.
However, an app can choose to revoke it when using ExoPlayer, e.g. if
no network is required and the app doesn't want to list this permission.
Support this use case by gracefully catching the exception in the relevant
places.

It's only thrown in an edge case on API level 20 and below. If it
is thrown it causes playback failure when playback could succeed,
by throwing up through configureCodec.
It seems better just to catch the exception and have the codec be
configured using the format's own width and height.

cache() opens all connections with unset length to avoid position errors.
This makes more data then needed to be downloading by the underlying
network stack.
This fix makes makes it open connections for only required length.

Using parallel adaptation for Formats without bitrate information currently
causes an exception. Handle this gracefully and also cases where all formats
have the same bitrate.

This prevents further unexpected updates if the MediaSource happens to
finish its preparation at a later point.

If a PlayerMessage throws an exception, it is currently not deleted from the
list of pending messages. This may be problematic as the list of pending
messages is kept when the player is retried without reset and the message is
sent again in such a case.

Adding an explicit option to clear all downloads prevents repeated database
access in a loop when trying to delete all downloads.
However, we still create an arbitrary number of parallel Task threads for this
and seperate callbacks for each download.
