Changes the behavior of requiresSecureDecoderComponent() to query the
session for whether a lowered security level has been requested
before querying the system to see what its default security level is.
As part of this, we added a new QuerySessionStatus() method to the
CDM that gets status info on a session-specific level, such as the
effective security level of a session.

After a change to the GPlay license server, it no longer accepts heartbeats
at the license server URL ( https://jmt17.google.com/video-dev/license/ ).
The CDM correctly reports https://jmt17.google.com/video-dev/heartbeat/
as the renewal URL but the current test code ignores the reported URL.
The license server then rejects the request and send back an empty
license response.
This causes WvCdmRequestLicenseTest.StreamingLicenseRenewal
and WvCdmRequestLicenseTest.StreamingLicenseRenewal to fail. Request
license tests have been modified to respect the renewal URL.

The CDM session was being destroyed before the policy timer was stopped
and before the session was removed from a list of active sessions. This
allowed race conditions, where the policy timer would try to evaluate
policy for a closed session. This led to segfaults.

A change was introduced between jb-mr2 and klp-dev that closed
the CDM session when the removeKeys mediaDrm APIs was called.
This was introduced because there is no way of unloading keys from
an OEMCrypto session.
This caused problems for Netflix, as an exception occurred when they
tried to close a session after calling removeKeys.
Reverting to jb-mr2 behaviour for now. b/11188818 has been opened to
track a longer term resolution.

Decryption calls though multiple threads may result in race conditions
between the setting of the key and the actual call to decryption.
This results in OEMCrypto errors when the buffer type used in
decryption did not match the key selected. This is addressed by
having the the two calls be in the same critical section.

In the OEMCrypto library, it is valid to call LoadKeys with an empty
mac key. The library should not update the mac and enc keys and
should not throw an error.
Since we have seen this behavior in several implementations, a unit
test should be added that verifies the correct behavior.

Swallows the error NEED_KEY if it comes back from AddKey(), as this
is expected behavior. (It means privacy mode is on and the key that
was just added was the privacy certificate, ergo the real decryption
key is still absent.) Note that this carefully does not squelch the
notification that comes from NEED_KEY, which is still necessary in
order for the app to make a second key request.
Also streamlines a test case that I noticed was overcomplicated for
what it did while poaching code from it for new test cases.
Also removes a .gyp file that was erroneously being copied to the
Android tree. Android does not use GYP.

A staging Root CA public key was used in earlier releases to verify
service certificates. These were in turn used to encrypt the
client identification. This met our needs for an end-to-end verification.
Now that the production Root CA and service certs are available
this change replaces staging certs with production ones.

In order to run all disabled OEMCrypto unit tests with one gtest
filter, one of them needs to be renamed so it matches the others.
These tests are disabled by default because they install a test

This CL turns off the verbose logging if LOG_NDEBUG is 1, or if NDEBUG
is defined. You can set the environment variable LOG_NDEBUG to 0 to
turn on verbose debugging for the CDM library on android.
Also, as in b/9672657, some applications call SelectKey when switching
between video and audio, which is much too verbose and affects
playback. I have removed the log statements for SelectKey.

Because we do not want to accidentally install a test keybox on a
production device, most of the oemcrypto unit tests are being disabled
by default.
If you wish to run these tests, you can override this choice, by

adb shell /system/bin/oemcrypto_test --gtest_also_run_disabled_tests

running the disabled tests on a device that has a non-test keybox

There is an ambiguity in the use of the signature length in
OEMCrypto_GenerateRSASignature. If the pointer to the vector is null,
the function should set the length parameter to be the size of the
buffer needed.
This ambiguity has been clarified in the documentation: the
length returned should be the exact length of the buffer. It
will be corrected in a future release of Qualcomm's L1. However,
we are putting this change in both as a stop-gap and as a
belt-and-suspenders fix.

In the android media DRM api test, provisioning is indicated, when a
generate license request command is issued after a switch between L1 and
L3. This is as expected as oemcrypto is unable to decrypt
the key wrapped earlier (bad padding). Subsequent provisioning request
and storage of wrapped keys complete successfully. If the same session
is used to reissue a generate license request command, the wrapped keys
and cert used are those present in memory from the initial retrival,
rather than rereading the new ones from persistent storage.
This results in a cycle of successful provisioning attempts followed
by generation of license requests commands which return a provisioning needed
error.
A change has been added to reinitialize the session and reload the
wrapped keys.
