Joey Parrish a35c2d621d Get timestamps from HLS TS segments
This adds a TS packet parser to find PTS values from the segments
themselves.

Issue #740

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 6069e76c4e Disallow ArrayBuffer.slice.
ArrayBuffer.slice isn't supported with two arguments on Tizen 2016.
This is a temporary fix that can be cherry-picked to v2.2.  A better
fix will be handled in a follow-up change.

Joey Parrish eb92f14ab5 Add more missing exports
See also commit 7a770783.

This fixes exports and externs that were broken in v2.1.0 and v2.1.1.

Generated externs are now verified and working with an external
Closure project.

Joey Parrish 7a770783a8 Fix export of DataViewReader
DataViewReader is referenced in the exported class Mp4Parser, so it
must be exported as well.  This fixes broken exports and externs in
v2.1.0 and v2.1.1.

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

Joey Parrish e4e200388c Fix encoding issues with Chinese subs
In many places we tried to guess the encoding of a piece of text.
This guess fails for Chinese UTF-8 text, and probably text in many
other languages.

However, DASH manifests, TTML files, WebVTT files, and VTTC box
payloads are all specified to be in UTF-8.  Rather than guess and
possibly fail, treat all text in these contexts as UTF-8.

Sandra Lokshina f1a4e25151 Add support for EMSG box.
Look for EMSG boxes in segments if the manifest signals their presence.
Update the manifest when a DASH EMSG box is encountered.
Dispatch an event with the content of the box for all other EMSG boxes.

Jacob Trimble 8daf53e329 Renamed shaka.asserts to goog.asserts.
Using goog.asserts will work with the compiler.  So rather than
simply casting a nullable value when passing to a method, we can use
an assert which will correct the type and print a log if it somehow
is null.

This is not the same goog.asserts found in closure library, this
simply calls console.assert, but it is not required to do anything
for the compiler help.

Jacob Trimble 846e7beb48 Unified comment spacing.
Before there were two style to indent comments after an annotation,
using 2 and 4 spaces.  Now this only uses 2 spaces.

Joey Parrish c934f426d8 Add new error type
This error type will be used for all internal errors, and will rely
on numeric error codes which can be easily checked by the application.

This also changes PSSH parsing to throw on errors instead of retaining
partial data.

Joey Parrish 4cc4e96dbd Overhaul license comments and file annotations
* Updates all Copyright years to 2015.
* Adds licenses annotations to all JS.
* Makes all licenses identical to avoid repeated appearance in the
  compiled output.
* Drops fileoverview annotations, which do not affect docs output.
* The linter still requires fileoverview on externs.

This patch required a newer closure compiler, since the previous
version we used had a bug regarding license annotations that caused
the license comment block to appear in the output once per file
regardless of uniqueness.

Joey Parrish 4d9177240a Revert "Adding license annotation to js files."
This reverts commit 8cb24652cb, due to
the fact that the new annotations caused our binary size to jump
by 52%.

The compiler preserves all 'unique' licenses, which causes trouble
since the comment blocks with the license annotations are not unique
and contain file overview comments as well.

We can re-examine this once we have restructured the license headers.

When there is no data section in the PSSH, we need to skip 0 bytes,
which should not be an issue.
