Joey Parrish a18dc01874 Remove broken HLS time offset code
We misinterpretted the EXT-X-START tag before.  Now, we ignore this
tag and parse segment times from the segments themselves.  This is
more robust for both VOD and live HLS content.

We avoid segment parsing when updating normal, well-behaved live
streams.  For poorly-behaved live streams, we will fall back to
segment parsing and recover.

This also addresses the issue of VOD content which does not start at
zero.  Instead of using configuration to make this playable, we will
now offset VOD content back to 0 automatically.

Jacob Trimble d125a54656 Use Uint8Arrays in text parsers.
This converts from using ArrayBuffer in the text parsers to using
Uint8Array.  This avoids doing extra buffer copies when using
ArrayBuffer.slice().

Closes #1022

Jacob Trimble 2c30ac70b1 Fix shaka.text.Cue in compiled builds.
The fields in shaka.text.Cue were getting renamed in compiled builds,
which would cause problems with custom text parsers or text
displayers.

Joey Parrish 7d36a2091f Parse default duration in WVTT MP4s
This adds support for WVTT samples with no sample duration by parsing
the default duration from the "tfhd" box.  If neither is provided, we
now log an error to the console.

Jacob Trimble 845c9af2f6 Fix text track reinitialization.
We should not reinit text until we are sure we are switching.
Otherwise, the new text parser won't have seen the init segment and
won't be properly initialized.

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.

Sandra Lokshina c6c6d05810 Move text-related files into their own directory.
This change creates a lib/text directory and moves all files
with text-related logic to it. It also lays the ground for
separating text parsing and display logic. (That change will
introduce even more files with text-related logic which will
crowd lib/media directory).

Issue #796.
