DRM certificate creation and expiration times are now validated.
* New DRM (default) certificates will have an expiration time specified
by the provisioning service.
When stored, the client will include the time the certificate was
received. This allows for expiration calculation to occur when client
and provisioning service clocks are out of sync.
When read out, creation, expiration and acquisition times are
validated. The certificate is checked for expiry by making sure
that the time at the client since the license was acquired is not
greater than the expiration period. The time information stored at the
client may be tampered with. The license service will perform an
expiration check and reject the license request if tampered with.
The expiration time may be set to never expires/unlimited. This is not
a valid value for creation or acquisition time.
* Pre-existing (legacy) certificates from upgrading devices will not
have an expiration time set by the provisioning service. Instead
the client will calculate an expiration time 6 months with + or -
a random two month period in the future. This is stored along with the
certificate.
When read out, if no expiration time has been set by the client, one
will be calculated and written out. The certificate will be declared as
valid. If a client calculated expiration time is present, the
certificate will be validated. In case of tampering, the license service
can reject license requests and force reprovisioning when appropriate.
* ATSC certificates will continue to not have an expiration time.
No additional validation is required.
Other changes for non-ATSC licenses involve managing both default and
legacy certificate co-existance. When checking for DRM certificates,
the default certificate is attempted first. This is followed by a check
for the legacy certificate, if the default certificate is not present.

This change includes additional fields in DeviceCertificate, License and
UsageInfo.
New DRM certificate will include a creation and expiration time.
In addition acquisition_time_seconds will allow the client to calulate
expiration time even when client and provisioning service clocks
are not in sync.
expiration_time_seconds will allow clients to expire DRM certificates
that do include an expiration time. A random value within a window
(4-8 months after update) will be calculated to avoid
a provisioning storm.
Drm certificate will be added to offline licenses. In a future release,
licenses will be removed on expiry and the certification information
that needs to be sent to the license service will be reduced.
This should reduce space overhead.
UsageInfo will use a certificate cache in case multiple usage info
entries use the same DRM certificate.

The CDM is responsible for telling OEMCrypto the underlying DRM
private key type when loading it into a session. To do this, the
CDM must determine and store the key type of a successfully loaded
provisioning response. The type of key is available from the
DRM certificate proto that is provided in the reponse.
This change introduces a class to contain the wrapped key and
type together. To store the type, the CDM device files have been
updated to include a key type with the DRM certificate and to
store from and load to the new class.
Unittests have been updated for using the new class where the
wrapped key was used before.

Client ID name-value fields in the license request share the same
namespace with app parameters and WV standard device information. As
a result, it was possible for applications to provide parameters that
could potentially fool the license server with spoof values.
This CL restricts the use of the fields that are common across both the
Android CDM and CE CDM. Currently, Android specific fields are
restricted by the MediaDrmPlugin layer, and there are no CE CDM

The conditional compilation for flagging the CDM and ODKiTEE logging
functions as printf-like was guarded by a check on "__gnuc__" or
"__clang__". However, GCC doesn't actually define "__gnuc__", it
defines "__GNUC__", all caps. Fixing this causes GCC to find a slew
of format-string errors that Clang was accepting. This patch fixes the
capitalization and the uncovered errors, most of which fall into one of
a few categories:
1) The format string and variable had different signedness. For these,
the format strings are updated to match the variables.
2) The variable was an array index that was not of size_t. For these,
the variables have been updated to be size_t and the format strings
have been updated to use %zu. A few index variables that weren't
actually used in format strings are also fixed to be size_t.
3) The code assumed the signedness of the internal representation of an
integer literal, enum constant, or enum variable. For these, I either
cast the input to a known type so that the format string is valid
regardless of internal representation or I switched to a hexadecimal
format string. The latter case is more useful on ODKiTEE enums where
the literal value is in the code as a 32-bit hexadecimal value
anyway.
This patch also adds missing integer casts to the enum literals in the
ODKiTEE logging header. (These are required for pedantic C99
compatibility when using literal values that do not fit into a 16-bit
integer.)
