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.

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.

- Remove the TS key rotation not supported check as there is nothing
to be done for key rotation in TS for SAMPLE-AES.
- Fix IV updated problem in new segments even if crypto period does
not change.
- Avoid duplicate EXT-X-KEY tags if it does not change.
- Make EXT-X-DISCONTINUITY-SEQUENCE match with number of removed
EXT-X-DISCONTINUITY.
- Added end to end test for HLS with key rotation.

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.

This addresses playready broken with clear lead = 0.
clear lead != 0 is still broken with playready on Edge. We think it is
likely an Edge bug, which does not support multiple sample entry boxes,
thus does not support clear lead.

- Added flag --mp4_include_pssh_in_stream, default to true. If it is
set to false, the encrypted mp4 stream will not include pssh.
- Align BytesOfProtectedData to multiple of 16 bytes for cenc.
- Set TrackHeader flag to kTrackEnabled | kTrackInMovie |
kTrackInPreview
- Move mvex to after trak, required by HLS
- Add cmfc/cmfs compatible brands except for avc3/hev1, where CMAF
requires single initialization switching set which is not supported.
- Set duration to 0 in tkhd, mdhd, mvhd.
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

test
- encryption_key, encryption_iv: allow injecting encryption key/iv from
command line

This will move ContentProtection element from Representation
to AdaptationSet.
Shaka Player already supports AdaptationSet switching
urn:mpeg:dash:adaptation-set-switching:2016;
ExoPlayer does not support it yet. Filed
https://github.com/google/ExoPlayer/issues/2431 to track the issue.
(ExoPlayer does not like having ContentProtection in Representation
anyway)

- Deprecated command line flags --profile and --single_segment.
'segment_template' in stream descriptors implies live profile
and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
static mpd for live profile; if not set, dynamic mpd will be
generated.

Current mechanism of using AdaptationSet @group is not spec compliant.
The spec compliant mechanism is to use supplemental descriptor with

- Tracks other than video are protected using whole-block full-sample
encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
equivalent to a pattern of 1:0. This is different to the non pattern
encryption counterparts.
- Also updated the code to allow the existence of other protection
schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.

KeySource is now an abstract class that is implemented in two
types WidevineKeySource and FixedKeySource. This also updates
fixed key encryption to use v1 PSSH boxes with the common system
ID.
This also updates the --pssh argument. Now it accepts full PSSH
boxes rather than data. Multiple PSSH boxes can be concatenated
together.
