Jacob Trimble 624acc66b8 Add curly braces to all blocks.
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.

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 d36168a55f Protect against WebVTT MPEGTS rollover
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.

Closes #1191

Joey Parrish 9759eddf54 Ignore style blocks in WebVTT
We do not support CSS embedded in WebVTT at this time.  Instead of
failing to parse the cues, skip the style block.

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

Joey Parrish aebb418a44 Fix TextDisplayer check for line and position
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.

Joey Parrish a7dec51f76 Make VTT settings parser more flexible
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.

Jacob Trimble 26bacb1489 Disallow unknown properties (3/5).
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 d8a3d8d2f7 Change jasmine.Spy type definition.
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.

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.
