Updated as many tests as we easily could. The tests that were not updated
all use live manifests or encryption that all require some "help", either
by dealing with times differing or with verifying decryption.

Created GetStream, a function used to get the stream descriptor for a
single stream. This allows for finer control over the stream compared
to the batch GetStreams.
Added "trick_play_factor" to GetStream so that the trick play factor
did not have to be added the stream descriptor value and "injected"
into the stream.

Created end-to-end tests for the segmented webvtt text in HLS. The
text stream is longer than both audio and video, so there are more
text segments than video/audio.

Created a method to diff the output dir against the golden copy
of the output dir. The goal with this is to simplify our end-to-end
test structure by removing the need to track the output files within
the test runner.
With all the golden output in one directory, this makes it easier to
setup end-to-end tests and even allows the golden files to be playable.
This should not affect the repo size too much as duplicate files will
only be stored in the git object store once.
Tests will migrate to this in separate CLs.

Looks like Safari does not like v0 tenc box.

This changes it to "WEBVTT" as described in the WebVTT spec.

- Add empty lines between different types of renditions to improve
readability.
- Group variants with the same audio/text group together, as it is
where the Adaptation occurs.
- Write master playlist after writing media playlists. This makes
more sense and it is also necessary to have the bandwidth of
the last iframe playist segment correctly computed.
- For fMP4, I-Frame segment must include the 'moof' header.
- Fix a problem that hls_iframe_playlist_name is not passed to
MuxerListenerFactory.

If no hls group name is given, we would default to "audio" but as
we are working to support text, this won't make sense to see
GROUP="audio" on a text stream.
Instead default to "default-audio-group" for audio streams. A specific
text default will be added later.

The IV was incorrectly updated across samples.
Created a new cryptor SampleAesEc3Cryptor specially for SAMPLE-AES
EC3 encryption / decryption. The new cryptor uses constant-iv, and
makes sure the IV is reset to the initial value at the beginning
of each audio frame and chained across syncframes within the the
audio frame.
Also added E-AC3 end to end test.

According to HLS spec: https://goo.gl/MiqjNd 4.3.4.1.1. Rendition Groups
- A Group MUST NOT have more than one member with a DEFAULT attribute of
YES.
- Each EXT-X-MEDIA tag with an AUTOSELECT=YES attribute SHOULD have a
combination of LANGUAGE[RFC5646], ASSOC-LANGUAGE, FORCED, and
CHARACTERISTICS attributes that is distinct from those of other
AUTOSELECT=YES members of its Group.
We tag the first rendition with a particular language in an audio group
with 'AUTOSELECT'; it is tagged with 'DEFAULT' too if the language
matches --default_language.

As specified in HLS spec (https://tools.ietf.org/html/rfc8216):
All audio EXT-X-MEDIA tags SHOULD have a CHANNELS attribute. If a
Master Playlist contains two Renditions encoded with the same

attribute is REQUIRED; otherwise, it is OPTIONAL.

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.

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.

Shared libpackager can be built by setting libpackager_type to
shared_library, e.g.
GYP_DEFINES='libpackager_type=shared_library' gclient runhooks
ninja -C out/Debug
will generate libpackager.so in out/Debug/lib directory.
Here is a few other changes to make shared_library builds and
tests pass:
- Add several test parameters to packager.h, which is needed for
testing.
- Create a protoc.gypi from build/protoc.gypi but depending on
protobuf_full_do_not_use instead of protobuf_lite, since we need
protobuf_full_do_not_use for text parsing and generation of media
info proto. Somehow shared_library build does not allow mixed use
of protobuf_full_do_not_use and protobuf_lite.
- Remove the use of LazyInstance in version/version.cc and use static
variable directly. This is because LazyInstance needs AtExitManager
which may not be easy to setup when calling GetVersion.
- Allow skipping testPackageWvmInputWithoutStrippingParameterSetNalus
with flag --shared_library, which is needed as shared_library build
does not support --strip_parameter_set_nalus flag yet.

'availability_time_offset' is not an attribute in MPD specification,

availability time. A similar effect can be achieved with standard

choose a suitable value.

Also updated major_brand and compatible brands:
- Set major_brand to isom (iso-bmff media file format) and made dash
a compatible brand
- Replaced compatible brand iso6 with iso8 since we use sthd for text
tracks
