Added a DB Upgrade path for converting content from version 1
to the version 2 format.

externs/shaka/offline.js now represents the data types for Shaka Player
Offline V2. All offline shaka player code uses the new version and all
V1 and transitional code has been removed.

Changed our stores in IndexedDB to use auto increment for the keys
so that we no longer need to track current ids anymore.

Create the pattern for how to handle database upgrades. As of this
change the only upgrade supported is from version 0 (no database).

Removed the reserve id from storage engine. Now adding an item to a
storage engine will return a promise that resolves with the id it
was stored under.

Before we added variants, there was no variant ids field on
StreamDB. To support legacy downloads, we created variants
for streams with no variantIds.
This change moves that conversion into DBEngine so that outside
DBEngine, streams will always have variantIds.

Changed the Storage Engine interface to know about the types that it
is expected to store. This allow the implementation to do more internally
as the scope of the object has been limited.

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.

After looking into the speeds for removing data from IndexedDB, it was
found that using a cursor was slower than the other methods. This change
takes the remove logic and changes it to remove each key as part of
one transaction.

On android the quota for offline content is much smaller than on
desktop. It was observed that when this quote was exceeded that
downloading offline content would stall but not throw and error.
It was found that instead of an error, IndexDB called onabort for
the transaction.
To fix this we now route onabort through the same code path as
onerror so that the abort will be treated and communicated as an
error back to the application.
Closes#747

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

This implements the workaround for a race in IndexedDB on IE/Edge.
If we don't get an 'upgradeneeded' event when we expect it, we will
close the connection and retry.

On IE/Edge, it is possible for the IndexedDB database to not be deleted
when the success callback is fired. If we immediately create a new
connection to that database, it will connect to the old database. Once
the database is deleted, the connection will no longer have the data.
This adds some assertions that we get an upgrade event. This also adds
the framework for the workaround, but doesn't add it so we can give
this revision in the bug report. This deliberately increases the
failure rates on IE/Edge.

To better support alternate storage mechanisms, this change abstracts
shaka.offline.DBEngine into an interface called
shaka.offline.IStorageEngine.
DBEngine has been changed to implement this interface, and allows the
addition of implementations that do not use IndexedDB.

This is part of the v2 equivalent of the ContentDatabase. This only
manages low-level interactions with the IndexedDB and wraps all
actions in Promises.
This also adds an in-memory version that is used for testing.
