Aaron Vaage 388d49cf98 Rename webvtt_output_handler files
Renamed all the files called "webvtt_output_handler*" to
"webvtt_text_output_handler*" to better reflect the class name
in them.

Aaron Vaage b69eb49f77 Add Missing ASSERT_OK Calls in Cue Alignment Tests
The SetUpAndInitialize function returns a status. We were not
asserting that it return an OK status. This change adds the
missing ASSERT_OK calls.

Aaron Vaage d56efd147a Disallow Copy and Assign For WebVTT Output
We don't want to allow any handler to be copyable or assigned-over
so this change enforces that for the webvtt output handler.

Aaron Vaage b3c148607f Simplify WebVtt Output
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.

KongQun Yang cf40accaa8 [HLS] Fixing AdCues handling in iframe playlists
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.

Fixes #378, #396.

Aaron Vaage 2e9c2fe024 Fix Cue Insertion at Text Stream End
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.

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.

Aaron Vaage 9a9f7d58b2 Update Cue Alignment Tests To Interweave Sample Data
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.
