- Add command line flag --test_packager_version to inject packager
version; packager_main.cc is also updated to use the same flag.
- Also add a MpdGenerator test in packager_test.py.

In the text sample box (for mp4) there was a value called
"data_reference_index" that was never initialized. This meant
that it took on various values can caused different results
between runs.

Renamed all the files called "webvtt_output_handler*" to

The SetUpAndInitialize function returns a status. We were not
asserting that it return an OK status. This change adds the
missing ASSERT_OK calls.

We don't want to allow any handler to be copyable or assigned-over
so this change enforces that for the webvtt output handler.
Change-Id: Ie0d59d6dbfb7a5e00bb4dd1422cd696d1a2d6072
Before, the webvtt output handler was written so that it could
share code between a segmented and non-segmented handler. As
we are not worried about that right now, this change simplifies
the handler to just be about segmented output.

Previously for the last iframe in a segment, we wait for the next
segment to arrive before writing the EXTINF tag. If an Ad Cue comes
in before the next segment, the EXT-X-PLACEMENT_OPPORTUNITY tag would
be inserted before the iframe in previous segment.

Instead of failing immediately, ignore unsupported audio codec when
parsing the source file, as there may be more than one stream in the
source file. This allows the supported streams to be packaged.
Closes#395.

The Cue class was from a previous WebVTT implementation and
is not used in the current implementation. It was missed when the
other classes were removed. This change removes it.

When originally implementing the webvtt parser, there was a
misunderstanding in what the BOM was suppose to be
(https://en.wikipedia.org/wiki/Byte_order_mark). This corrects the
misunderstanding.

Make sure to use the output format when given when setting up our
tests. Not doing so results in text always being set to "vtt" when
the output format is "mp4".

Problem : Text samples have variable length and therefore act
more like continuous samples whereas audio and video
act more like discrete samples. Since we use sample
start time, a cue event could be inserted after the
start time of the last text sample and never get
inserted as there are no more samples.
Change : After all streams have requested flushing, we make sure
to collect all remaining cue events from the sync point
queue and insert them into each stream.

Create an end-to-end test for ad cues. This test's final result is not

be fixed by a later CL.

Uses protobuf JSON util instead.
packager/base/json_writer comes from Chromium base. We are going to
replace it with abseil, which does not have a JSON library.
The code is much more cleaner now.
This is unfortunately, at the expense of increased output binary size.
packager binary increases by another 100KB.

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.

In the cue alignment handler, instead of storing just one cue, store
a full queue. This will make it easier to handle text streams that
end before audio and text.

In the cue aligner, instead of storing the cue event, store a

sending the cue event downstream.

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.

Use a common hint for all stream states as the hint is always

Problem: Sending samples to the cue alignmenet handler did
not reflect what was more likely to happen. In our
tests we would send all the samples for one stream
then all the samples for another stream. This created
some special cases that would either not happen in
reality or miss cases that would likely happen in
reality.
Changes: Changes all tests to dispatch samples in an interlaced
pattern that better reflects muxed content.

In H265Parser::ParseSliceHeader, the parser does not handle
byte_alignment() from the spec. byte_alignment() reportedly contains
at least one bit, which is not handled right now.
See Section 7.3.2.12 Rec. ITU-T H.265 v3 (04/2015).
Also added a few size sanity checks in H265Parser to make sure the
code does not crash if an invalid input is provided.

RST only accepts two forms for option argument:
- Begins with a letter and consists of [a-zA-Z0-9_].
- Begins with "<" and ends with ">"; any characters except angle
brackets are allowed internally.
Updated documents to obey the above rule.

Packager uses ThreadedIO to write media segments and manifest /
playlists. There was a possibility that media segments write being
delayed and scheduled after updating manifest / playlists.
This CL fixes the race condition.
Also added a note on how segments can be synced to cloud storage to
avoid the race condition during file sync.
Also added a live WebM test.
Fixes#386.
