RtspMediaSource uses the timeline update paradigm from ProgressiveMediaPeriod.

The size of rtspLoaderWrappers must match the number of tracks exposed by the
RTSP session (a track is exposed if its media description entry appears in
DESCRIBE's SDP response).

When retrying with TCP, the old code will start loading all exposed RTSP
tracks, regardless of whether they are selected.
The fixed code will only start loading selected tracks.

The current code does not catch the IAE thrown when building a MediaDescription
or SessionDescription. This CL catches the IAE and propagates it as a
ParserException.

Issue: #9014.

The old version's retry logic will not work if using authentication.
Specifically, we use the same authentication parameters from the previous
session, and the RTSP server will reject such parameter.

In this fix, we reset the authentication info on retry. Further, we retry the
last request on receiving a 401 Unauthorized, rather than sending out another
DESCRIBE request.

RTSP message body's format is not regulated by the RTSP spec, meaning it can
use either CRLF or LF as its line terminator. The old code assumes every line
ends with CRLF (RTSP message and the message body); the new code will rely on
the Content-Length information to receive the bytes for the message body.

`SurfaceTexture` provides a transform matrix with each buffer. Previously
gldemo ignored this but it is important to apply it to have the video render
properly.

The transformation matrix from the surface texture includes flipping so this
change removes the hard-coded flipping from `a_texcoord`.

A renderer is disabled (without being reset) in two situations:
* When transitioning into a period that starts with a discontinuity
* When stopping the player with setForegroundMode(true)

Before this change the behaviour of `MediaCodecRenderer` when disabled
(but not reset) depended on whether the content being decoded had an
associated `DrmSession`:
* For content without an associated DRM session the MediaCodec instance
  was kept alive.
* For content with an associated DRM session, the MediaCodec instance
  was released. This was to prevent the DRM session from staying alive
  and continuing to make license refresh network requests while the
  player was stopped in 'foreground mode'.

This change removes the second bullet, and keeps MediaCodec instances
alive in both the secure and insecure case. This will result in the
DRM machinery making occasional license refresh network requests (at
a frequency defined by the license policy) while the player is stopped
and in 'foreground mode'. This network usage is considered to be a
'limited resource' as described by the `ExoPlayer#setForegroundMode`
javadoc.

This means that switches between secure content (or between secure and
clear content when `MediaItem.drmConfiguration.sessionForClearTypes`
indicates a secure decoder should be used for clear content) should
keep the same video decoder, thus avoiding the 'black flash' that occurs
on some devices when switching the surface away from a secure decoder.

This change introduces a third 'state' for `DefaultDrmSessionManager`:
It's been fully released (prepareCount == 0) but at least one of its
sessions is still active.

In this state new acquisitions are rejected (`(pre)acquireSession()`
calls will fail) but the machinery to support the existing sessions
(ExoMediaDrm and MediaDrmHandler) is kept until they're all released.

This change will allow us to remove the TODO in MediaCodecRenderer
that resolves Issue: #8842.

PiperOrigin-RevId: 376193952

In a follow-up change I will add an additional test to ensure these
events continue to be correctly handled when DefaultDrmSessionManager
has prepareCount==0 but a non-null ExoMediaDrm instance.

Many of the setters are ignored unless others are set - this change:
* Lists these conditions exhaustively.
* Uses more concise language to avoid overshadowing the main details
  of what the setter sets.
* Tweaks the language from 'is ignored' to 'shouldn't be called', to
  open up the future possibility of throwing an error if these are
  called without the 'required' setter also being present (see
  Issue: #8957).

The docs on setLicenseUri say it's optional, and it has been since
https://github.com/google/ExoPlayer/commit/379cd8a04f0bf44a9422a08440223581b2657d74
(which should have changed this javadoc too)

Authentication sequence in RTSP:

- Server replies "Unauthorized" to our DESCRIBE request, and includes the
  necessary information (i.e. realm, digest nonce, etc) in WWW-Authenticate
  header

- After `RtspClient` receives the response, we

  - Parse the WWW-Authenticate header, stores the auth info. The info is saved
    for all further RTSP requests (that all need to carry authorization headers)
  - send the second DESCRIBE request with the Authorization header.

The method openSocket in RtspMessageChannel does not actually open a socket.
The 'open' term refers more to opening the message channel.

The callbacks received RTSP messages and RTSP sending errors are now invoked
directly from RtspMessageChannel's internal threads. It's up to the handler
implementation to decide which thread to handle the messages.

Previously, RTSP interleaved binary data is posted onto the playback thread
for handling, the playback thread then adds the received data to a queue.
A loader thread will later dequeue the data and process it.

In this CL, the binary data is sent through a separate listener, on
RtspMessageChannel's RTSP receiving thread.

Some RTSP servers will offer multiple WWW-Authenticate options. We wanted to

Currently acquireSession() fails with an NPE from
checkNotNull(exoMediaDrm). A follow-up change will result in exoMediaDrm
sometimes being non-null while prepareCount==0 (and in this case we
still want acquireSession() to fail).

preacquireSession() doesn't currently fail in a way the caller can
observe - the same NPE is thrown, but asynchronously and it doesn't
propagate out of the background thread. Throwing directly seems
preferable since it's a clear bug to be trying to preacquire sessions
from an unprepared/released manager.
