This undoes the previous change to silence harmless C++11 narrowing
warnings and instead changes the code to no longer trigger them. The
fix was to delcare the type of our PSSH prefix constant to be uint8_t*
and then convert it to char* at usage-time rather than defining the
not-technically-char* data as a char* to start.

This copies over formatting changes from the Widevine CDM repository
that resulted from running clang-format with Google style on the
shared core/ directory. It also copies over some rewordings of log
messages that were made at the same time.
Aside from the changed log messages, this should not affect behavior
or functionality.

The key set ID is now available earlier, in order to support the CE
CDM 4.5 interface, which needs it at key request generation time, not
later at key response receipt time. It is still possible to receive
the key set ID at key response time, for Android's purposes. Either
API may now be passed a pointer to store the ID in, which may also be
left NULL if this is not needed.

Adds unit tests which cover several cases, including five which are
fixed in this patch:
* Find a Widevine PSSH after a PSSH with non-zero flags.
(We have no control over another provider's abuse of the flags field,
so we should not give up if such a PSSH appears before ours.)
* Find a Widevine PSSH after a v1 PSSH.
(CENC now specifies a general v1 format. We don't have to support it
directly in the CDM, but we do have to skip it gracefully.)
* Find a Widevine PSSH after a non-PSSH box.
(This would be unusual input, but we can easily recover from it.)
* Parse a PSSH box with a size field of 0, which means "the rest of the
buffer."
(This would be unusual input, too, but is technically allowed for any
MP4 box.)
* Parse a v1 Widevine PSSH box, ignoring the new fields we don't need.

resemble its purpose and the name it is known by on Android.

This is a copy of the widevine CL:
https://widevine-internal-review.googlesource.com/#/c/12742/
If a session is closed at the same time as an OnTimerEvent is
processing an event, there could be a race condition between the two
threads. This CL adds a lock that prevents a session from being
removed from the list while the timer is currently processing an
event.
If CloseSession is called while the OnTimerEvent method is active, the
session will be added to a dead list, and deleted when the timer event
has finished.
This CL does not address the main problem in bug 19252886, but
one bugreport, netflix_log_3.txt, indicates there may have been
a problem with the CDM timer.

This is required because these makefiles contain a module that's
building agains the "current" SDK and will need to add an explicit
compile time dependency on the apache API.
Note that no runtime dependency is needed because the app targets
SDK version 12 (?!!).

Netflix reported that after pulling power while their app is active,
the app isn't able to restart. This is because the license file for
session keys isn't getting synched to disk, so the data is still in
the buffer cache when the device shuts down. Calling fflush and fsync
on the file ensures the data is persisted to disk. fclose alone
doesn't do fsync.
In testing, I also noticed that the license file was being rewritten
every second which is hard on the flash filesystem. The timer thread
was modified to avoid these frequent writes.

If a key query occurred before a license was received an UNKNOWN_ERROR was
returned. This now succeeds but returns no information (an empty container).
Also licenses that were already expired when received were not marked as such.
This did not cause violations in playback rules but caused an exception when
they were queried.

Cherry pick of the widevine change
https://widevine-internal-review.googlesource.com/#/c/12082/
If the level 1 oemcrypto library loads and initializes, but has the
wrong version or does not have a valid keybox, then the level 3
fallback is used. However, in those cases, the level 1 was not
terminated properly. This caused a resource leak on some platforms.
With this CL, in OEMCrypto_Initialize, the level 1 library Terminate
is called if its Initialize was called and the level 1 library will
not be used.

This project is still using stlport (without telling the build system
about it), which was causing (broken) stlport headers to override
libc++ headers, leading to a broken copy of std::enable_if, which in
turn caused <atomic> to fail to compile. Since this project has
prebuilts that will need to be updated before this project can
actually move away from stlport, tell the build system that it is
still using stlport for now.

OEMCrypto may report an HDCP status of "No HDCP device attached/using
local display with secure path". This is not propagated upto
the server as an appropriate HDCP value did not exist in the
license protocol. This has now been added. Netflix has requested that
this be reported.

The OEMCrypto did not save the usage table correctly after a key was
loaded and not used.
Also, oemcrypto uses the keybox to verify and sign the usage table.
On library initialization, the usage table was being loaded before the
keybox, so the signature was not verified correctly.
Both these problems have been corrected.

Our recommendation to OEMs is that they support a table of at least 50
usage entries in OEMCrypto. If more usage entries are stored, the PSTs get
added to the CDM but are LRU'ed out of the OEMCrypto usage table. When the
CDM queries those usage entries, OEMCrypto will return a
OEMCrypto_ERROR_INVALID_CONTEXT. Rather than return an error and have
MediaDrm throw an exception, CDM should delete this PST and return the
next usage entry, when queried.

Several unit tests in cdm_engine_test.cpp and request_license_test.cpp
were failing regularly. These were caused by either:
1) The device was not provisioned.
This has been fixed by adding a certificate provisioning step in the
test setup for the cdm engine tests and changing the existing
provision steop in the request license tests to provision for both
security levels.
2) The device was hitting a flaky server.
This has been fixed by switching from the GooglePlayServer to the
Widevine server.
3) A null pointer introduced when testing secure stops with an app
id. This has been fixed by directly injecting the app id in the unit
tests.
4) Flaky network connections. The unit tests were requesting data
from the server and were timing out after 3 seconds. I changed that
to 12 seconds.
5) The tests were searching for an end-of-line marker to find the GLS
header in the license response message. The end-of-line marker was
present in a valid DRM message for almost 1% of the test cases. This
code has been replaced by searching for the string "GLS/1" at the
begining of the HTML body.
I also added test_printers.cpp that defines functions used by GTest to
print error codes by name instead of numeric value.
This CL changes unit tests only. It does not change any production
code.
