Temporary licenses do not allow for license information to be stored
in any form, whether it is usage information or persisting license
information. Information should not be stored even if can_persist is
set to true and a PST is specified as those are suggestions rather than
a requirement.

The test WvCdmEngineTest.LicenseRenewal is split into two tests. One
test verifies that the renewal may be fetched from the server
specified in the license. The second test verifies that the renewal
may be fetched from the same server that the license was fetched from.
These might be the same server, but when we run against an
experimental server, a staging server, or UAT Nightly, these
will be different.

(This is a cherry-pick of http://go/wvgerrit/104184.)
UBSan has detected several places where our code tripped over what is
technically Undefined Behavior when handling enums, although in practice
any compiler would still generate safe code.
Some of these were places a variable was not being initialized and thus
was filled with garbage data. These have been fixed.
Understanding the rest depends on a bit of C++ trivia I had certainly
never heard before: An enum that doesn't specify its backing type will
frequently have a gap between the range of values the compiler will let
it take (which is limited only by the size of the backing type assigned
by the C++ standard) and the range of values for which the C++ standard
defines the behavior. (which is limited by the minimum number of bits
needed to hold the largest valid enumeration entry) So, for example, an
enum containing ten entries numbered 0 through 9 would be stored in
memory as an int and could thus take any value in the range of an int.
But it only takes 4 bits to represent the numbers 0 through 9. The
largest number that can be represented in 4 bits is 15. So reading the
value of a variable of this enum type when its stored value is outside
the range 0 to 15 is undefined behavior.
An enum that specifies its backing type is not subject to this because
it is defined behavior to access any value representable in the backing
type if one was explicitly specified.
If you think this sounds a bit silly, you'll be happy to know it doesn't
apply from C++17 onwards and most compilers generate code that handles
the undefined behavior values correctly.
Nonetheless, to appease UBSan and protect us from any compilers that
actually rely on this undefined behavior for optimizations, I have
defined backing types for all our enums. I have defaulted to the type
the compiler was already using (int32) and have deviated only where an
enum exists to be compared to or filled from a protobuf field and that
field in the protobuf is unsigned, in which case I used a uint32.
In the case of the CE CDM exported API, this also required changing our
enums from C-style to C++-style.

To help with debugging failures in HTTP requests during unit tests,
this CL adds logging for Google's debugging response header fields.
These fields are of the type "X-Google-*" or "x-google-*" and provide
information such as the service name, server cell, error details, and
other details that can help isolate the cause of failure on the
server's end.
An additional unittest has been created to test the parser for the
header fields.
Tests that are known to exprience HTTP failures have been extended
to include logs for these fields should they be present.

The OEMCrypto method for usage table capacity can return zero to
indicate that the usage table size is not explicitly limited. The
CDM must handle this case with regard to the CDM's usage table
management and information querying.
The usage table initialization tests are extended to include cases
where the table does not have a defined limit.
AddEntry() was missing call to update the usage table header after
creating a new usage entry. This call is now included and required
additional changes to the usage table unit tests.

In v16, OEMCrypto specifications required that an error be returned if
multiple attempts are made to load an offline license into a session.
This caused the GTS test testConcurrentDrmCertificates to fail. It was
introduced to verify that a license could retrieved and loaded into a
session and then restored. This was based on an app use case.
Ideally we would like to disallow a this behavior but need to make sure
it is not being used by apps.
For now this will be allowed. If detected, the CDM will reintialize the
OEMCrypto session and allow the license to be restored.

When an offline license is reloaded, if it does not have a usage entry
to indicate when the rental clock was started, the start time defaults
to 0 in the ODK library (in OEMCrypto). This CL changes the code to
start the rental clock in this case. It does this by signing a dummy
message, which triggers the ODK library to start the rental clock.

When OEMCrypto is v16, but the license server is v15, we should not
create a new nonce for a license renewal. However, the request does
need a nonce or the license server will not generate a valid key
control block. So we should use the nonce that came from the original
license.

After changes made to how the usage table is defragged by the CDM,
it was determined that there is no use in selecting more than a single
entry from the usage table to evict. The only failure that can occur
when evicting an entry is if the last entry is in use, in that case,
evicting other entries will still result in a failure.
This change cleans up the LRU algorithm and test cases to reflect
the new functionality.

to a flaky server failure unrelated to CDM code. Most of these tests
are now re-enabled to ensure the multi-threaded license requests is
