We currently don't check which session is causing a network transfer
(it could be a preloaded item in a playlist). To clearly associate
network transfer data with sessions, we need to keep track of
transferred bytes and transfer time per session.

We may fall back to a different sample MIME type because
a) the sample MIME type inferred from the input is not supported
by the muxer or b) no encoders are available for the the requested
sample MIME type.

With this change, the MediaCodecAudioRenderer configures the MediaCodec
to not downmix audio only if spatialization can be applied. This way,
decoders who are downmixing by default are left doing so when
spatialization cannot be applied. The renderer re-initializes the codec
when spatialization properties change mid-playback.

TransformationRequest is otherwise immutable, so if we modify the
transformationMatrix in place (done before this cl) this may cause
confusing behaviour for apps when they reuse a TransformationRequest.

Currently, we keep the values for dropped/played frames, audio underruns
and current formats from the last session, causing double reporting
of counters and wrong track change reasons for formats. All these
values should be reset when the active session is finished, so that the
new session can start from scratch.

Currently, we always end the current session if onSessionFinished is
called. However, the finished session may not be the active one (for
example when discarding prebuffered items in a playlist). To make this
code more robust, we can save the active session id explicitly and only
end this session.

After implementing fallback, it won't always be possible to
differentiate between muxer and encoder as the cause of an output
format not being supported.

This change enables the ImaServerSideAdInsertionMediaSource for multi-period content. The global ad playback state is split into pieces for each period and the window and period durations are calculated accordingly in the ServerSideAdInsertionTimeline.
For multi-period live content (DASH), the ad playback state is not set with this change. This is deferred to a follow up CL. Splitting is very tricky. For each timeline update the windowStartTimeUs may vary for some milliseconds relative to the start of the period.positionInWindowUs. This requires to either introduce some fuzzy logic or to choose a different approach than for multi-period VOD. Because mistakes within the playback states of subsequent moving live windows produces crashes, it seems sensible to defer this for now and keep this change in a separate future CL (unblock further work, easy to rollback).
In this state, live DASH stream are working and the ad overlay is placed over the player correctly bu the SDK. However, ads are not reported by the position discontinuity event. Similarly, the player.isPlayingAd() does never returns true when a ad period is playing.

This CL implements fixing the input format to the encoder spec. Fixed
parameters include:
- MIME type
- Profile & level
- Resolution
- frame rate, and
- bitrate

The MediaMetricsListener currently just looks at the mime type and
doesn't use the inference based on the URI if no mime type is set.
Also change default type to OTHER to avoid classifying streams from
URLs without clear file extension as progressive.

Instead of having types in flac inherit types in vorbis, make types in
vorbis inherit types in flac. This is a bit of a hack and somewhat
messy, but it retains backwards compatibility.
Collapse the two variations of `VorbisUtil.buildMetadata` into a single
method called `VorbisUtil.parseVorbisComments` that only takes a list
of vorbis strings, compared to previously where it would take strings
and picture frame instance. Any code that relied on the old signature
now either concatenates picture frames and vorbis comments or copies
vorbis comments into an existing metadata instance.
Simplify how the comment header is parsed and eliminate a few possible
bugs in the process, such as:
- Metadata being overwritten directly by the comments header.
- The packet being rewound to 0 if it cannot find a comment header,
which might result in the cursor being moved to a bad position.
In the old `flac` module, superclass the deprecated types under the
moved types in the `vorbis` module. This ensures backwards compat
with existing library users.
Adaptive video and audio selections will be limited to formats with
the same level of DecoderSupport and HardwareAccelatationSupport, unless
specifically allowed by new flags.
If different levels of decoder support are available, prefer primary
over fallback decoders and hardware-accelerated over software decoders
(in this order). For video, also prefer more efficient codecs, if both
are supported by hardware-accelerated primary decoders.

This change moves the video track selection to the generic
selection method introcuced for audio and text. This ensures
we can apply the same criteria for fixed and adaptive video
track selections. Implicitly, this reorders the preferences
for adaptive tracks to give non-quality preferences (like
preferred MIME type or preferred role flags) a higher priority
than number of tracks in the selection.
