KongQun Yang b209aeeb7a Remove the usage of JsonWriter in SimpleHlsNotifier
Use protobuf utilities instead.

packager/base/json_writer comes from Chromium base. We are going
to switch to abseil which does not have a JSON library.

This is unfortunately, at the expense of increased output binary size.
packager binary increases by about 300KB due to:
- Protos cannot be compiled with LITE_RUNTIME any more.
- Additional protobuf library needed to convert between JSON and proto.

KongQun Yang b5a73fc1d5 Refactor ProtectionSystemSpecificInfo class to struct
This is in preparation of supporting entitlement license API, where
common encryption server may return concatenated PSSHs directly.

Refactored ProtectionSystemSpecificInfo into a struct containing
concatenated PSSHs. This will make it easier to pass PSSHs around.

Also, most of the time, users of ProtectionSystemSpecificInfo do
not care what is in PSSH; so moved PSSH box parsing and building out
of ProtectionSystemSpecificInfo.

KongQun Yang 60d7a4b2d5 Make MediaPlaylist accept HlsParams as contructor param
And for HlsNotifier and SimpleHlsNotifier as well.

This will make it easier to add preserve_segments_outside_live_window
param in a later CL.

KongQun Yang adc9549e2d Add new URL fields in MediaInfo
The file_name fields will be used to solely indicate file paths on the
designated file system, and they are used to do normal file operations,
including file creation, file updating and file removal if needed;
added new xxx_url fields, for the URLs that should appear on DASH
manifest or HLS playlists.

xxx_url are the URIs of the media in the manifest. The fields are
converted from file_name fields but adjusted to be relative to DASH
manifest path or HLS playlist path, optionally with base_url prepended.

Previously the file_name fields are converted in place to indicate
URLs when passing to manifest / playlist builders. The original file
names were lost, which made it difficult to remove files outside of
live window.

Now that the input file names are preserved. File system APIs can
operate on the original file names while manifest / playlist generation
functions can operate on URLs.

KongQun Yang 8257eea804 Bug fixes and clean-ups for I-Frame playlists
- 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.

KongQun Yang 32d26094ba [HLS] Support AUTOSELECT and DEFAULT in EXT-X-MEDIA
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.

KongQun Yang ae17159b73 [HLS] Fix init segment URL isn't respecting folder locations
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.

Problem occurs when the media playlists are in a sub-directory under

Also make sure the path separator is "/" in URL instead of "\" on
Windows.
