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.

When deleting a usage entry, a crypto session may need to be closed
and reopened if a usage entry has previously been loaded. Before closing
this session, the usage entry/usage table header information should be
saved.
This is for completeness rather than correctness. Looking at code,
usage header and entry information are saved after the license
release has been generated. This change might be helpful in case
that changes in the future.

This CL adds a test base that installs a test keybox and catches nonce
flood errors for all CDM tests.
In order to do this, a new class is added called a
CryptoSessionFactory. The default factory just creates a new
CryptoSession. All places in the code that create a new CryptoSession
now call the static method MakeCryptoSession, which uses the current
factory to create a CryptoSession. If MakeCryptoSession is called and
there is no current factory, a default factory is created.
The CryptoSession constructor is now private, so that we do not
accidentally try to create one without using the factory.
For the new test base, we first create a special test
CryptoSessionFactory that creates a TestCryptoSession. The test
factory catches the first call to MakeCryptoSession and injects an
installation of the test keybox after OEMCrypto_Initialize is called.
The TestCryptoSession injects a sleep statement and a retry whenever
it detects a nonce flood.
Test: current unit tests still pass.

* Build CE & Jenkins CDMs With BoringSSL from third_party/
Author: John W. Bruce <juce@google.com>
[ Merge of http://go/wvgerrit/37120 ]
Up until now, integrators have been responsible for providing a
compatible crypto library for use by the CE CDM. (either OpenSSL or
BoringSSL) After this change, this decision will no longer be in their
hands. The CE CDM build will always use the copy of BoringSSL in
third_party/, which will be statically linked with our library with
hidden visibility. This allows us to better control what crypto library
we use and will prevent continuing problems with trying to support both
OpenSSL and BoringSSL.
Unfortunately, BoringSSL began using C++11 in mid-2017, and we can't
support C++11 right now. Until we can, we need to use a C++11-free
version of BoringSSL for libssl. The CDM itself will continue to use a
recent BoringSSL, as it only needs libcrypto. But the unit tests that
need libssl have to use the legacy version.

* Refactoring to allow encryption of client ID
Author: Rahul Frias <rfrias@google.com>
[ Merge of http://go/wvgerrit/37460 ]
The code has been restructured to allow encryption of client
identification in provisioning requests. This will be enabled
when server side changes have been made (b/69427217).
* Additional information is included in the Client Identification
portion of the provisioning request.
* Client identification will be encrypted with a service
certificate provided by the app/client. Platform changes
to enable passing this to core are needed. If a service certificate
is not provided, a default one associated with the production Keysmith
will be used.
* Switched APIs in CdmEngine to take a service certificate for
provisioning rather than licensing. Service certificates for
licensing are session based and passed as properties from platform
code.

This creates some CdmResponseType errors which may be reused
PARAMETER_NULL, NOT_INITIALIZED_ERROR, REINIT_ERROR.
I have made changes to a few classes to report these errors.
Will work on additional classes in a separate CL.
