The Widevine Android CDM should not allow itself to be instantiated
without an app package name, as this breaks SPOID protection.
Unfortunately, pathways exist prior to Android Q that allow this to
happen, and we cannot break these devices by changing the behavior now.
As such, we will only refuse to allow instantiation without an app
package name on devices first launched with Q and later.
This change also migrates the WVDrmFactory and its tests away from
explicitly naming friend classes for individual test, in favor of the
now-recommended "test peer" pattern.

Merge of http://go/wvgerrit/77608http://go/ag/6543431 modified the entitlement key session to select the
entitled content key if it had just been loaded in so that there's a
valid current content key loaded in OEMCrypto. However, this did not
account for the case where you have two entitlement to entitled key
pairs. If OEMCrypto does not select the key when you switch from the
first pair to the second pair back to the first pair, OEMCrypto will
still be using the key from the second pair during decrypt. This CL
changes it so we SelectKey each time to make sure that we update the
current content key.

The Level 3 uses the getUniqueID method to uniquely identify devices to
save device keys. This method needs to be consistent and as part of the
method, the length is set. In previous versions, this length isn't set,
but starting from Pi, it is. What this means is that decryption of the
device keys fails, and therefore offline licenses are lost. As a
workaround, we attempt to decrypt the device keys with the length
parameter and with the default if we failed to decrypt. Since the
generation number is also encrypted by the unique id, in the case where
we succeed in decrypting with the default, we reencrypt the generation
number so it can be read in when we handle the usage table. Finally, we
reencrypt everything with the correct length unique id.

Now that we have C++11, many places that do string formatting or parsing
can be replaced with std::to_string() or one of the std::sto*() family
of functions. This patch updates places that do simple stringifying or
parsing to use these functions. Some parts of the code are left
untouched because they were using StringStream to do more complex
actions, such as constructing more complex output or checking the status
of the parsing.
