Jacob Trimble f130dffcef Enable eslint indentation rule.
This is a fully automated change.  The linter will fail because the
extra indentation caused line-length errors.  These won't be fixed
automatically.  They are fixed in a follow-up to make this one fully
automated.

Jacob Trimble 0dd64074b9 Only allow one statement per line.
With the new style rule, we cannot have two statements on the same line.
So we can no longer have an "if" on a single line and we cannot have
an arrow function with a body on the same line as when it is used.
This is mostly a manual change.

Jacob Trimble 47daf49f31 Use arrow functions for callbacks.
This is an automated change to convert use of "function" functions
to arrow functions.  This doesn't change all uses of bind() that
could be converted.  This also doesn't remove all "function" functions.

Jacob Trimble c81389741f Prefer const over let.
A coming update to the Google eslint config will require using "const"
over "let".  This makes that one change to isolate the big changes.

Joey Parrish cbfe4f82a4 Fix warnings found by a newer compiler version
This is only some of the warnings produced.  These were not errors,
but we should fix them anyway so that we can adopt stricter settings
in future.

Theodore Abshire 8ea237c214 Fixes how the MDAT is read for VTT in mp4 content.
Previously, we would read each individual VTTC and VTTE box in the
MDAT and associate them with durations in the TRUN. This worked for a
lot of content, but if sampleSize is defined in the TRUN, a duration
might refer to multiple VTTC boxes.

This changes the VTT in mp4 reader to parse the MDAT based on the TRUN,
to account for such situations.

For the moment, this only accounts for a single MDAT, and assumes that
the MDAT contains nothing but vttc or vtte boxes, listed in order.

Theodore Abshire d46e8fdf92 Typo fixes and rewording in comments, part 6
This makes a large number of small typo fixes. It also rewords a
number of comments and JSDoc descriptions, and does some
formatting standardization.

This doesn't fix every single issue, but it fixes a lot. Notably,
there were some formatting issues I declined to standardize due to
ambivalence on what the proper standardization would be; for example,
when and where empty lines should show up in JSDoc.

Jacob Trimble b512db87dd Convert 'var' to 'let'/'const' (8 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.

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().

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).
