Joey Parrish 7e6a0f38ff fix: Correct license headers in misc. files
This corrects/normalizes license headers in misc. files, such as
config files, docs, build tools, tests, and externs.  This does not
affect the compiled output, and is only done for consistency.

Issue #2638

Jacob Trimble 011749e95f Standardize argument comments.
This changes the eslint rule to enforce a strict pattern for the
argument comments.  The comment must appear before the argument and
must be /* foo= */.  This still ignores line comments.

Joey Parrish 41a8664dba Make segment references independent of periods
This is a step along the way to flattening periods, and also
simplifies a few small things in StreamingEngine and tests.

Joey Parrish c13830e535 Augment SegmentReference with offset and window
SegmentReference used to have presentationTimeOffset, which,
subtracted from the period start time, was then _added_ to the
timestamps in the segment by MediaSource.

Now, SegmentReference has a timestampOffset field, which is exactly
what MediaSource's timestampOffset field is set to on the SourceBuffer
before this segment is appended.  For DASH, this is periodStart minus
presentationTimeOffset.

This also adds append window start & end times to the
SegmentReference.  Now segments can be appended to SourceBuffers
without reference to the period.

Note that start & end times of the SegmentReference in each segment
index are still relative to the period.  This will change in a
follow-up.

Joey Parrish 64896d70b0 Use shorter license header
This reflects changes in Google's policy on JavaScript license
headers, which should be smaller to avoid increasing the size of the
binary unnecessarily.

This also updates the company name from "Google, Inc" to "Google LLC".

Joey Parrish 7fe97b841b Move fields to SegmentReference
To prepare for flattening out the manifest structure to remove
periods, this change moves initSegmentReference and
presentationTimeOffset fields into the SegmentReference object.  This
way, the segments on either side of a period transition or HLS
discontinuity can have different offsets or init segments, eventually
allowing us to create a single array of SegmentReferences for
multi-period content.

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 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.

Jacob Trimble b2bde18a3d Convert 'var' to 'let'/'const' (5 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 4067c20a7c [ES6] Replace gjslint with compiler linter & eslint
The eslint configuration is derived from analyzing the style of our
sources as they are now, plus a few tweaks.

In particular, we have disabled checks for undefined variables and use
of console, both of which the compiler handle with greater precision.
The compiler already knows what is defined in the environment through
our externs, and has specific exceptions for the use of console (demo,
tests).

We have also disabled a few checks that we should use, but will
require many changes to the code: no-unused-vars, no-redeclare,
and comma-dangle.

This commit also fixes several types of eslint errors that were easy:
  - no-useless-escape (unneccessary escape characters in Regexp)
  - no-constant-condition (using true/false/0/1/etc in if/while)
  - no-fallthrough (caught an actual bug in one EME polyfill)
  - no-irregular-whitespace (we had a UTF-8 nbsp in externs)
  - no-cond-assign (using an assignment inside a conditional)

To satisfy stricter provide/require checks in the Closure Compiler
Linter, we will no longer use provide/require at all in tests.  We
will still use provide in test utilities (test/test/util/) since it
sets up the namespace for us.  But we will not use require there
because there is no deps management for test code.

Joey Parrish b54ca32835 Do not assume same timescale in manifest and media
According to the DASH spec, the timescale in the manifest need not match the
timescale in the media.  Therefore, we should be applying scaled
presentationTimeOffsets in segment index parsers, since the two scales might
differ.

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
