Moved all code dealing with jobs into its own class so that the
packager code does not need to worry about initializing, running,
or stopping jobs.

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
codec but a different number of channels, then the CHANNELS
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.

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.

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.

Moved build instructions and docker instructions to separate docs.
Removed command samples which are no longer needed as we have better
tutorials now.

- 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.

The HLS manifests output by the packager did not have the RESOLUTION
attribute on EXT-X-STREAM-INF tags. This change adds the resolution
tag when resolution values are present.

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,
but used to calculate availability_start_time to adjust segment
availability time. A similar effect can be achieved with standard
blessed suggested_presentation_delay flag.
If suggested_presentation_delay is not set, player is expected to
choose a suitable value.

Widevine license server added support for protection_schemes recently;
If CENC request includes protection_scheme in the CENC request, server
will return with a PSSH with protection_scheme filled in.

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.
