String obfuscation hides string literals from static analysis but
requires string literals be used inside protected functions.
- Enable string obfuscation for all function groups.
- Change some global `std::string` to `const char[]` to ensure that
the `std::string` is constructed inside a protected function so
that string obfuscation correctly applies to the string literal.

Plugin to provide getPropertyByteArray("deviceSignedCsrPayload")
which returns the signed CSR payload for device registration. It
queries both BCC and device info to be set in plugin before calling this
getPropertyByteArray("deviceSignedCsrPayload") method. The returned csr
payload will be used by assemble the device CSR by the caller for device
registration.

This patch adds a new interface that partners must provide to
Cdm::initialize(), ILogger. ILogger replaces stderr as the sink to which
logging messages are sent. For partners that still want to log to
stderr, a reference implementation that logs to stderr is provided.
As a side-effect of this, many test-related source files had to be
updated to thread the new parameter to Cdm::initialize() through them.
This also necessitated adding a new variant of FormatString() that can
be called with a va_list directly so it can be called from other
functions that take varargs.

Flags are to be used in new tests when creating tests that potentially
take a long time to run. Certain test suites are intended to be quick
and may skip certain long running tests.
New slow tests should check these flags and skip using GTEST_SKIP().

"client_version" is an optional, information field in the protocol for
license requests. It was requested that the CE CDM includes this
information in the license request. It does not hurt to include this
information in the Android license requests too.
If, for some reason, the client cannot provide this information, the
request is still sent out as normal. No reason to prevent an otherwise
valid license request due to a missing optional field.
Note: This field is directly in the LicenseRequest message and not the
ClientIdentification message.

Devices may be revoked by the provisioning server resulting in an
error message contained within the provisioning response. The CDM
core currently returns an error, but the CE CDM would map this to
an kUnexpectedError, which does not provide the information to the
CE client to react. This situation is not immediately recoverable,
but may provide certain apps to use a different DRM plugin if they
support such a thing.
Documentation and tests are needed.

GetDeviceInformation() and GetDeviceSignedCsrPayload() are added to
cdm_engine and crypto_session, so that they can be queried by DRM
plugin. This is to allow the wv drm HAL to be able to extract BCC and
CSR payload to build CSR for prov 4 device registration, such that we
don't need a separate RKP HAL to do this job.
Changes to the DRM plugin to use the exposed methods will be in the
coming CL.

There are three changes here that should help reduce the
amount of duration test failures caused by clock skew.
First, we reported some skew when the test expected playback
to start immediately after loading the license. However,
with round-off, this could easily be more than 1 second. So
this does not warrent even a warning.
Second, the fake and real clocks were only synced after
computing how long to sleep. This is fixed by moving
SleepUntil to the TestSleep class and having it sync before
computing the delta and after doing the sleep.
Third, I am guessing that some failures due to unexpected
lenience were caused by the rental or playback clock being
started at the end of signing the license or the end of the
first decrypt instead of the beginning. We work around this
by recording how long these operations take, and then adding
this extra time at the end of the check for FailDecrypt.

For provisioning 4.0 devices, the DRM certificate serial number
was changing on a reprovisioning attempt or factory reset. The
app parameters sent up in the client identification name-value
pair field were being filtered out in provisioning requests.
This has been corrected for provisioning 4.0 stage 2
(DRM certificate request). There is no need to include them for
stage 1 (OEM certificate request).
The test case WvCdmRequestLicenseTest.ProvisioningSpoidTest
was created earlier to ensure that SPOIDs and DRM certificates are
stable. Unfortunately due to another bug b/250099615, the RKP service
was holding a connection to the Widevine TA for provisioning 4.0
devices. When native tests ran as their own process, L1 would fail
to load due to a connection failure and the test would run as L3.
The tests passed for provisioning 4.0 devices Pixel 7 and 8 when
they should have failed. This gave us a false sense of confidence
that the SPOIDs were stable.
For now a workaround is to run a shell command to kill the widevine
TA before running native tests.
$ adb shell pkill -f -9 widevine

For devices with a large number of usage entries, when restoring the
usage table a capacity check is performed. This checks that a new
entry can be created. This test was originally added as some devices
might enter a "stuck" state the table cannot be initialized.
To perform this test, a temporary crypto session is created and an
entry is created for that session. After successfully creating that
entry, the entry is deleted. However, because the session was left
open, the entry could not be deleted.
This change closes the capacity-check-session before deleting the
entry, as well as includes additional logs for helping future debugs.

Partners have requested that we log HDCP information during certain
operation:
1) Current and max HDCP capability when calls to decrypt or select
key failure due to insufficient or mixed HDCP levels.
2) Current, desired and default HDCP level when video contraints
are not met.
To avoid spamming the logs, decrypt failures are only logged on their
first occurrence, and unmet video constrains when one of the
requirements change.
