This patch also fixes a bug which was introduced in
https://widevine-internal-review.googlesource.com/c/packager/+/38040
where it was inconsistently assumed that AdCueGenerator would be MIMO
while connecting with other handlers and at the same time it was assumed
SISO in the AdCueGenerator class. Now we assume SISO everywhere.

The spec allows having more than one 'mdat' boxes even if it is not

The keys can be specified in --keys option, with the form of
label=<label>:key_id=<32-digit hex string>:key=<32-digit hex string>,label=...
There can be multiple "label=..." block. The DRM label can be one
of "AUDIO, SD, HD, UHD1, UHD2" or a custom label.
Mark --key and --key_id as deprecated. We can achieve the same result
with --keys=label=:key_id=<key_id>:key=<key>.
Also add a new optional field in stream descriptor: drm_label, which
is used to overwrite the internally generated DRM label for the stream.
If not provided, the DRM label is generated automatically based on
audio/video information, e.g. resolution.
Code changes:
- Merged RawKeyEncryptionParams and RawKeyDecryptionParams into
RawKeyParams.
- Make FixedKeySource accepts RawKeyParams as input.

Problem occurs when the media playlists are in a sub-directory under
master playlist. If base_url is not set, segment URL should be
relative to the media playlist.
This only affects fMP4 as TS does not have init segment.

To help isolate the differences between audio/video and text in
preparation for adding the better text support, this change moves
all audio/video job creation and text job creation into their
own functions.

This fixes shared_library not able to compile problem.
Also removed StreamDescriptorList and replaced with expicit
comparison to make the code clearer.
Also removed an out-dated DCHECK that mpd_notifier and hls_notifier
does not co-exist.

Use std::shared_ptr<const uint8_t> with a custom deleter to
represent MediaSample::data_ instead of std::vector<uint8_t>.
MediaSample::data_ can be shared by multiple MediaSamples and it is
immutable. A new data instance must be created if the clients want to
modify the underlying data. The new data instance can be transferred
to MediaSample using provided MediaSample::TransferData function.
This avoids unnecessary data copying.

Took the test structure for trick play and made a common test
structure that can be used for new tests. The next tests to
use this structure will be the new WebVtt pipeline.
Change-Id: I5faca306b8a2bd16b9f945d1ff5c336aed82bc35
This change create some matchers and text functions that
will be used by the upcoming webvtt work.

Before the trick play handler would have one input and multiple
outputs. The normal media handler API for adding handlers had to
be ignored when setting-up the trick play handler.
This changes the trick play handler to have one input and one output.
It uses the standard AddHandler method calls. When initialized, the
trick play factor must be provided.
This included a run of 'clang-format' over all edited files.

To allow more tests to use the MediaHandlerTestBase and get access to the
helpful creation methods, this change moves the use of FakeMediaHandler
and setting up the graph to a sub class.
Change-Id: I90dd151e3c96d8fbe4bd02a1d6b11e66a279d95b
Created media handlers that make testing a handler easier by providing
methods to send messages from upstream and check messages downstream.
Change-Id: I7b3ba3a51bcf0d73bcaacd46b2dcbc16f87d8694
Moved build instructions and docker instructions to separate docs.
Removed command samples which are no longer needed as we have better
tutorials now.
