Jacob Trimble 29f39077dc Convert 'var' to 'let'/'const' (2 of 9).
This is part of a change to convert all usages of 'var' with either
'let' or 'const'.  This takes a conservative approach for 'const' where
it will only be used for aliases and storing the "original" values in
tests.

Jacob Trimble 554cffc95c Fix SegmentTemplate w/ duration.
We incorrectly added the presentationTimeOffset to the segment times as
a fix for #1164.  The correct fix is to use the include the PTO in the
time structure passed to the text parsers.  This is a partial revert
of 207505.

Issue #1164
Closes #1232

Joey Parrish 20750504fe Fix presentationTimeOffset in SegmentTemplate
We were not previously applying presentationTimeOffset in
SegmentTemplate w/ the duration attribute.  This fixes the DASH parser
to correctly apply the offset in this case.

This also fixes an issue in which segment times could stretch past the
end of the period or even past the end of the presentation, causing
StreamingEngine to fail period transitions afterward.

Closes #1164
Closes #1163 (PR to address 1164)

Sandra Lokshina 051531b80f Add support for HLS playlists with type EVENT.
HLS Live comes in two flavors: LIVE and EVENT.
EVENTs append segments to the end of the playlist, but do not
ever remove segments. LIVE can both append segments to the end
and remove segments from the beginning of the playlist.
This CL lays the ground for supporting both types and introduces
support for EVENTs.

Issue #740.

Michelle Zhuo d67764b5ff New Error Code for Content unsupported by Browser
Previously "UNPLAYABLE_PERIOD" exception is thrown when a browser
doesn't support the container or codecs in a piece of content, which is
confusing to developers and customers.
Changing it to "CONTENT_NOT_SUPPORTED_BY_BROWSER" exception.

Test manifest:

Closes #868.

Jacob Trimble adb8da4764 Disallow unknown properties (1/5).
This is part of adding a new conformance rule to add additional type
safety.  This will disallow using properties of unknown types or using
unknown properties.

The first parts will be fixing errors caused by the new rule.  These
are backwards compatible, so can be applied before the rule is enabled.
Once all the errors and bugs are fixed, the rule will be enabled.

Jacob Trimble e5ce395f37 Implement gap jumping.
The bulk of the logic for gap jumping is handled in Playhead.  It
tracks the current buffered ranges and jumps over any gaps that appear.
It listens for a special browser event ('waiting') for when the video
element runs out of playable frames.

This change also removes the logic for jumping gaps at the beginning
of the timeline.  This is handled by the more general gap jumping
logic and works cross-browser.

Finally, this updates the buffering logic to only count the amount of
content buffered (i.e. ignoring the gaps).  This fixes some bugs where
gaps in the content can result in StreamingEngine buffering forever
since it thinks only a little is buffered.

This includes full implementation of the logic, but this doesn't close
the issue since there aren't any integration tests yet.  Those will
be added next.

Jacob Trimble 575f2ad109 Add an indicator for critical errors.
This adds a severity field to Error objects.  This can be used to
detect whether an error is recoverable.  All the same errors are still
reported so the field can be ignored.

There are two possible values:
* RECOVERABLE means that the Player will try to recover from the error
* CRITICAL means the Player will be unable to continue and must call
  load() again

Closes #564

Jacob Trimble 68e870dc9a Add support for EventStream elements in DASH.
This also makes the Playhead ignore duplicate regions.  This simplifies
manifest updates in DashParser by having it add every Event tag it
sees.  The DASH spec doesn't specify how we should detect duplicate
entries or how events are fired.  So to avoid firing all the same
'timelineregionadded' events on every manifest update and getting
multiple enter/exit events, we will simply remove duplicates.

Closes #462

Jacob Trimble 2ca962a33c Refactor ManifestParser.start to accept an object.
Rather than accepting multiple callback methods as separate arguments,
now start() will accept an object.  This will allow us to add new
callbacks without breaking backwards compatibility or adding
additional arguments.

Joey Parrish c7e73e0115 In-progress recording (IPR) support, phase 1
This change creates a new model which divides DASH streams into VOD,
IPR, and live.  It is possible to create manifests which do not fit
into any of the three categories according to our model, so we now
assert that our input fits cleanly into one of the three.

Inline manifests used in our tests had to be updated to conform to
the new model.  All external test assets have been verified to fit
into these categories.

This is phase 1 of IPR support.  There should be no behavior change
in this CL.

In phase 2, we will make various other parts of the library aware of
IPR so that IPR-specific behaviors can be achieved.
