The keybox validation needs to be done separately from initializing
the library so that we can support Keybox OTA Reprovisioning.
If L1 loads, but the keybox is missing, the initialization should
succeed. When the keybox is validated, the adapter should try to look
for a keybox on the filesystem. if none is found, it should either
return NEEDS PROVISIONING or an error.

(This is a merge from the Widevine Repo of http://go/wvgerrit/134310.)
This patch fixes code that would trigger -Wshorten-64-to-32 by
implicitly narrowing a variable from 64 to 32 bits. Most of the time, it
does this by making the implicit conversion explicit. The cause of most
of these is that OpenSSL uses "int" for the length of things rather than
size_t. (While BoringSSL sometimes uses int and sometimes uses size_t.)
One exception is LogBoringSSLError(). We have a couple copies of this
function around, and they varied slightly. This patch brings them all
in-line, which conveniently also removes any code in them that would
deal with integer variables.
GetRandBytes() now takes a size_t and downcasts to BoringSSL's native
int internally, so that callers can pass in a size_t value as they would
expect.
There's also an interesting case in oec_session_util.cpp. Because
BoringSSL and OpenSSL disagree about the width of an error code, we have
to use the "auto" type for a temporary variable that holds an error, in
order to retain compatibility with both.

certificates with license preservation]
Due to uncertainties of when the provisioning service will
launch, we are disabling expiration for legacy DRM certificates.
If the feature does not launch in time, existing DRM certificates
will expire and be replaced. Offline licenses associated with these
expired DRM certificates will fail to load.
Expiration of legacy certificates will be reenabled at a later time.
The main portion of feature, the issuing of new DRM certificates with

When the CDM creates a new usage entry for an offline or streaming
license, the new entry is immediately moved to the lowest available
entry index that has been marked as vacant (kStorageTypeUnknown).
When a license is released, its meta data that is managed by the CDM
is cleared; however, the usage entry's index is marked vacant, but it
is not released. This creates wasted entry space in the usage table.
Unfortunately, defragging the table is computationally expensive and
may not be able to actually free up much space depending on when it
is performed.
For a typical user, this will likely not be an issue as the table
can get quite large compared to the number of licenses an app uses
and the table is partially cleaned on each boot.
GTS tests, however, have reached a point where they fill the usage
table before all tests are complete. This is causing many unexpected
failures for devices. Most of these tests release their license, but
the CDM never reaches a state where it can clean up the table.
By moving newly created entries to the lowest available index directly
after creating the entries, the table never needs to grow unless all
entries are in use. Clean up is now almost never required.

There was an issue encountered by some vendors with how the usage
table was initialized on some devices. Previously, the CDM would
open an OEMCrypto session first, then initialize the usage table
(loading existing or creating a new one). On these devices,
OEMCrypto_CreateUsageTableHeader() and OEMCrypto_LoadUsageTableHeader()
would fail if there were any open sessions.
This CL changes the initialization process to create/load the usage
table before opening an OEMCrypto session.
This change also lays the ground work for another usage table fix
to address GTS tests failure.
In the process, several of the functions for the usage table have been
split up into smaller chunks of code. This required additional changes
to the usage table unittest to keep them up to date.

that the app no longer relies on that behavior, we are reverting

The CdmEngine logs had both too much and too little information.
Since our logging has been enabled to print function names natively,
many of the log information has become superfluous. Needless
information has been removed, and many of the important INFO logs have
been reduced to only the information not present in the function name.
Some of the INFO and ERROR logs were missing identifiers to match
failures with the same session request should the failures take more
than a few milliseconds to occur. CDM session IDs and key set IDs
have been included in all the logs that _appeared_ to have a slow
operation between the top of the method and log.
To help make enum values more readable, several enums-to-string
functions have been implemented. These converters are intended for
INFO logging and as such, do not log any addition information should
the enum be out of range.
To help make empty and null identifiers more readable in the logs,
empty strings will be logged as <empty> and null strings will be
logged as <null>.
While working through the "cdm_engine.cpp" file, a few minor changes
have been made:
- Adjust if statements to match with Google C++ style guidelines
- Skipped anything that was not obvious
- Added a const qualifier to variables where appropriate
- Moved some null checks to the top of the method
- Only where sequence is non-critical to normal operation
- Removed unnecessary string to vector to string conversions
- Reject empty |force_session_id|
- Already enforced on CE CDM code and not uesd on Android

Also, the tests CdmUseCase_LicenseDuration were failing with a v16 CDM
