Alex Dale b8a80cf3e8 Fixed HLS parsing of bad content IDs. 
[ Merge of http://go/wvgerrit/207456 ]

When parsing Widevine's HLS key data, the key details are contained
in a data URI in the HLS X-KEY URI field.  The data of the URI is a
base64 encoded JSON object, containing the information required to
generate the license request.  The "content_id" field of the JSON
object is expected to be a base64 encoded; however, the HLS parser
did not verify that the decoding was successful.  In the event that
was not successful, the decoder would return an empty string, which
the parser would attempt to access the first element by reference
which may be a null reference.

In C++, creating a reference from a null point (without actually
accessing the value) is undefined; however most C++ implemenations
will not cause a segment fault; but it is not guarenteed by the
standard.

This change checks if the decoding was successful before attempting
to store the decoded "content_id" value.

A unit test is added to ensure that a parser fails gracefully.

README 

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
