8a82379e81 Unittests will retry provisioning if failed.
[ Merge of http://go/wvgerrit/84490 ]

The unit tests will now make at most 10 attempts to provision
themselves before declaring failure.

This change is made to help with flaky provisioning requests that
have been experienced on the Jenkins build server.

63b2ea86d9 Allow CE CDM to Create Sessions Without a Service Certificate
(This is a merge of http://go/wvgerrit/84510)

When the CE CDM 3.5 behavior around service certificates was originally
implemented, it allowed sessions to be created if a service certificate
had not yet been installed, in keeping with the EME spec. However, the
service certificate in use at session creation time was cached, and so
there was a bug where any sessions open before a service certificate was
installed would never be updated with any future service certificates.
The code also caused problems for Android. When it was merged to master,
it was fixed to simply not allow session creation on CE CDM without a
service certificate. However, this created an impedance mismatch between
the CE CDM and EME that has caused pain for Shaka Player Embedded,
Chrome, Chromecast, Fuchsia, and likely every partner that is trying to
implement a fully-compliant EME stack on top of CE CDM.

Removing the code that blocks session creation without a service
certificate is easy. Fixing the bug that motivated it is not. Removing
the caching is not possible because Android needs it for certain
behavior on its end. So instead, the CE CDM will have to iterate over
all open sessions and update their service certificates if the installed
service certificate changes.

5bfdd515eb Fewer parameters for storing and retrieve license information.
[ Merge of http://go/wvgerrit/84990 ]

Storing and retrieving licenses from device files had required 15
parameters to the DeviceFiles methods.  Now, licenses information is
bundled together in a single struct `CdmLicenseData`, similar to
`CdmUsageData`.

ee56d93454 Creating a new RNG and replacing rand().
[ Merge of http://go/wvgerrit/84607 ]
[ Merge of http://go/wvgerrit/84608 ]

The primary goal is to replace the use of `rand()` with the random
number generators provided with the C++11 standard.

This simplified generator wraps some of the technical aspects of the
<random> library and provides an interface for uniformly distributed
integers.

As part of the `rand()` purge in the CDM, all uses of the C random int
function in `core()` have been removed.  Places that previously used
`rand()` now use `CdmRandom` facilities.

ee995d5fae Replacing NULL with nullptr in core/
[ Merge of http://go/wvgerrit/84647 ]
[ Merge of http://go/wvgerrit/84648 ]

Replacing most instances of C's NULL with C++'s nullptr.  Also changed
how a NULL check is performed on smart pointers.  They provided an
implicit boolean operator for null checks, meaning the underlying
pointer does not need to be compared directly (as it was in some places
before).

Note that clang-format has performed additional changes to some of the
test files that have not yet been formatted.

79a28e5ddb Changed UsageTableHeader::Shrink to tolerate over shrinking.
[ Merge of http://go/wvgerrit/83804 ]

There is a private helper method in `UsageTableHeader` which is used by
other methods to shrink the table by removing a specified number of
entries.

Prior to this change, if `Shrink` was called to remove more entries
than there are, it would: 1) do nothing and 2) return `NO_ERROR`.
Obviously, at least one of those action should change.

Instead of doing nothing, it will simply remove all the entries from
the table and return `NO_ERROR`.  A warning will be logged that it was
requested to shrink by more entries than there are.

Four (4) new tests have been created to ensure that `Shrink()` works as
expected.

[ Merge of http://go/wvgerrit/82232 ]

The new function `ArraySize` will only work for compile-time fixed-length

This will replace the commonly used macro `N_ELEM()` which uses `sizeof()`.

b60f75805d Unify log level for tests
Merge from Widevine repo of http://go/wvgerrit/79463 and
http://go/wvgerrit/82383

Several tests explicitly set the log level. This CL unifies that a
little bit. When running the unit tests by hand, on android or for ce
cdm, the log level is 0 (ERROR) and can be incremented on the command
line using the "--verbose" switch.

When running on the desktop, you can set the environment variable
VERBOSE_LOG to "yes", and the log level is set to VERBOSE.  This is
done by the buildbot so you can see full logs in the build archive.

When running with the test bed (i.e. Mod Mock) you can edit the
options.txt file and set log_level to 0=ERROR up to 4=VERBOSE. if you
are using the run_current_tests script, you can create a file in the
linux directory called override_options.txt and add the line
log_level 4

This CL only changes test code.

5ea429ee2b Don't Use StringStream When It's Overkill
(This is a merge of http://go/wvgerrit/76063)

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.

dfc5909d0c Segfault When Running Jenkins Tests... Sometimes
(This is a merge of http://go/wvgerrit/71330)

The Service Certificate unit tests actually relied on the ability to
call Properties::Init() multiple times to clear previous mutable state.
Unfortunately, they didn't check the return code that could have told
them their mutable state wasn't being cleared and instead proceeded to
use a pointer which — depending on compiler — could be totally valid and
allow the test to pass or could be invalid and cause a segfault. You can
read the bug for a fuller explanation of the mechanics.

The fix is twofold. First, the tests will now assert out if insertion
into the property set map fails, preventing segfaults. Second, a helper
has been added to Properties that allows tests interested in
re-initializing Properties to do so. The default behavior for most tests
remains the same: Properties can only be initialized once and subsequent
calls to Properties::Init() are ignored.

This patch also fixed a few formatting issues I noticed.
