c014da7da3 Correct when OEMCrypto_GetOEMPublicCertificate is called
[ Merge of http://go/wvgerrit/148469 ]

OEMCrypto_GetOEMPublicCertificate needed to be called
before the OEM private key was loaded due to a bug in OEMCrypto.
The bug has been addressed and the call can now be removed.

OEMCrypto_GetOEMPublicCertificate is only applicable to
devices with OEM certs as their root of trust. Devices with
keyboxes (or BCC) as their RoT would return a spurious
error OEMCrypto_ERROR_NOT_IMPLEMENTED. Removing the call
addresses this as well.

[ Merge of http://go/wvgerrit/148158 ]
[ Cherry pick of http://ag/16982989 ]

A rare race condition was found where a key is selected as the session
is closed.  This results in a null pointer dereference in
CryptoSession::SelectKey().  Two additional checks have been added to
SelectKey() to prevent this from occuring.

fd00a8af24 Remove old test license holder
[ Merged from http://go/wvgerrit/143750 ]

The old test license holder would generate a minimal license response,
but could not correctly mimic important server logic introduced in the
v16 server. Since all integration tests now have policies on the UAT
server, we do not need these minimalist license responses anymore.

6cda6717a9 Reboot test: Initialize fake clock
[ Merge of http://go/wvgerrit/143630 ]

When we run a test with the fake clock, the clock had been initialized
to the current time, or to 0. This causes a problem for reboot tests
because the clock might go backwards over the reboot. With this
change, we monitor the clock at the end of one reboot pass and
initialize the clock for the next pass based on the previous value.

df23c7da03 Fix errors being hidden by Protobuf warning-disabling
(This is a merge of http://go/wvgerrit/140850.)

This patch fixes a number of minor issues in the codebase (mostly
instances of 0-as-nullptr, but also some member shadowing and a missing
override) that were being hidden by the fact that depending on Protobuf
disables these diagnostics. And which will be unhidden when a later
patch removes that behavior from Protobuf.

5606e7dae3 Upgrade MOCK_METHOD to googletest 1.10
(This is a merge of http://go/wvgerrit/139989.)

Googletest added a new, more powerful MOCK_METHOD() macro in 1.10. This
patch updates all our usage of the old MOCK_METHOD family to the new
macro. Full details can be found at
https://github.com/google/googletest/blob/release-1.10.0/googlemock/docs/cook_book.md#creating-mock-classes
but in brief, the new MOCK_METHOD() replaces the entire old MOCK_METHOD
family and has the following advantages:

1) No need to count parameters or update the macro name when changing
   parameters.
2) No need for a different macro for const methods.
3) The ability to specify override, noexcept, and other function
   qualifiers.
4) The macro order is now the same as C++ method definition order:
   Return Type -> Name -> Arguments -> Qualifiers

In addition to upgrading all our usage sites to the new macro, the
addition of the override qualifier to our MOCK_METHODs helped uncover
several cases where we were using MOCK_METHOD to override methods that
didn't exist. This is a great example of why the override qualifier is
so useful. These places have been updated, by removing the invalid and
unused mock method.

uses the device ID from the keybox as its source of truth.  For
devices which have lost their keybox, OEMCrypto_GetDeviceID() was
assumed to return ERROR_KEYBOX_INVALID if that was the case; however,
Qualcomm's implementation was returning ERROR_NO_DEVICEID.  Given that
both error codes are appropriate, the CDM has been updated to accept
both as an indication that the device ID cannot be retrieved, and that
the null device ID should be returned.

df0cfa2daa Fallback to L3 if provisioning lost
Merge from Widevine repo of http://go/wvgerrit/142349

If a provisioning request is sent, but no response is loaded, we
should fall back to L3. This covers the case where the OTA request is
malformed and the provisioning server ignores it.

This might happen if the device has a bad KM key.

31faf51933 Fall back to L3 if L1 has test keybox
Merge from Widevine repo of http://go/wvgerrit/142150 (part 2)

For an EVT device, without a keybox or with a test keybox, we want it
to fall back to L3. However, when running the unit or integration
tests it should continue running tests with test keybox. This will
allow us to test L1 oemcrypto on an EVT device, while still using an
EVT device for dogfooding video content at the L3 level.

This CL modifes the HIDL and non-HIDL plugin, so it was hand merged to
