This change fixes tests on Chromecast by loading tests later in the process. Test scripts are now dynamically inserted by boot.js, rather than loaded by Karma. The bootstrapping code then awaits the completion of that before starting the Karma frameworks (Jasmine) to run the tests.
This also removes the use of goog.provide/goog.require in tests and test utils. We don't need to load test utils or library sources dynamically in each test, and this gives us more explicit control over script loading and ordering.
Closes#4094
This PR fixes#3242 where for some live streams using segmented VTT, text timings are relative to segment start instead of being absolute.
The PR introduces a new setting: `manifest.segmentRelativeVttTiming: boolean` allowing such alternative timing offset calculation.
The setting is off by default, preserving the current player behaviour.

The new eslint found many style errors which have now been corrected.
It also complains a lot about atomic update issues that do not seem to
exist, so that rule has been disabled.
This upgrade will allow us to adopt eslint's "id-denylist" instead of
the older "id-blacklist" rule, the name of which violates new Google
guidelines about respectful language.

1. Add support for multiple layers of nested cues.
2. Add support for anonymous span.

When there is no X-TIMESTAMP-MAP header, the HLS spec states that the
client should map 0 to 0, effectively. That means we were wrong to
offset the cues by the segment time.
Since DASH IOP states that segmented text should be packaged in MP4,
this should not affect compliant DASH content.

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.

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".

For VOD, the first segment of every Media Playlist in every Variant
Stream must start at the same media timestamp. Thus, we can get the
start time once and store the value, and all the streams can use the
value directly. For live, we assume for the same.
This change reduces calling getStartTime_() from 15 times to once for
Angel One, and also fixes the text segment timestamp issue.
Also removed associated methods that no longer needed.

It turns out that, on some browsers, incomplete XML does not properly
parse. This means the parseFirstCue tests did not work on those platforms.
This modifies those tests on platforms that do not support partial XML;
when no support is detected, it instead tries to get the first cue
from a non-partial segment.
This also modifies the HLS parser to only load partial text segments if
the text parser supports it; otherwise, the hls parser will load full
captions in order to extract start times.

Previously, when the text engine tried to load the start time of
a segment, it would parse every cue in that segment, then check the
time of the first cue. This was judged to not be a significant
performance issue, as parsing cues is a fast operation. However, it
did have an unintended side-effect: in some situations, this method
was being passed partial segments; notably, the HLS parser would load
the first 2048kb of the stream's texts to extract timing data.
If the caption parsers tried to actually parse an incomplete caption,
they would error.
This gives the text parsers "parseFirstCue" methods, and uses those
methods when it only needs the first cue anyway.
Fixes#2037

Instead of checking each property separately, just use
jasmine.objectContaining. This also adds a utility for matching a
number that is close to an expected value. This is required when
matching objects with toEqual().

Creating them in beforeAll will usually cause test contamination, so
they should be created in beforeEach instead so they are reset for
each test.

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.

A coming update to the Google eslint config will require using "const"

CSS style 'direction' supports only horizontal directions, (left to
right, right to left), and writing-mode supports horizontal top to
bottom, vertical left to right, vertical left to right.
Separating the field 'writingDirection' to two fields 'direction'
and 'writingMode', so that they're the same as the css style names.

Google style guide requires adding curly braces to all block statements
even if it is only has one line. This fixes it by using eslint's
--fix flag followed by running clang-format to reformat the change.

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.

When the MPEGTS field rolls over in HLS live WebVTT, we need to avoid
our parsed cue timestamps rolling over as well. To achieve this, we
simply ignore the X-TIMESTAMP-MAP tag once the segment index is built.
Rollover in TS video and audio segments is handled by mux.js already.

We do not support CSS embedded in WebVTT at this time. Instead of

If line and position are null, the corresponding VttCue should have
default values. Before this change, we treated 0 as null, which would
have prevented setting line or position to 0.

We can now accept non-integral values in settings, such as
"position: 100.0%" instead of just "position: 100%".
The regex change is very simple, so we would also accept invalid
settings such as "position: 12.34.56%" or "position: ...%", both
of which would result in NaN in the output.

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.

The old definition using a union with a Function causes problems. The
compiler tends to treat this as an unknown type, so we loose type
safety. The new types ensure full type safety, at the cost of needing
to "convert" the spy when it is used as a function.

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).
