Compiling with GCC 7 revealed that a function call in this test was
missing an argument. It meant to be passing the output protection level
to the function, but because of optional arguments, it was instead
passing it as the fourth argument.
Fixing this revealed that the test cases for the test were incorrect in
one case, which has been fixed to expect the correct results.
Thankfully, this part of the code does not appear to have been broken
while the tests had this hole.

The provisioning doc changed names, and I accidentally added the new one
without deleting the old one.
I also added a watermark to the newer one.

Information stored in files are serialized and protected by an MD5 hash.
When files cannot be read because the MD5 hash computed over it
fails verification, the file is deleted. This allows for recovery.
However if the protobuf deserialization fails we return an error
but do not delete the file. When errors of this sort occur
with usage information files, the CDM cannot recover.
removeAllSecureStops() will fail as well and new licenses
with PSTs cannot be processed. In order to recover the file will
be deleted when a protobuf deserialization error occurs.

Nominally, OEMCrypto probably shouldn't modify the buffer descriptor we
pass into OEMCrypto_DecryptCENC(), but in practice, we know some
platforms do this, so we make defensive copies in
CryptoSession::DecryptInChunks() just in case. Turns out, some devices
also behave like this in OEMCrypto_CopyBuffer(), so we should also be
doing defensive copies in CryptoSession::CopyBufferInChunks().

Locks in earlier releases controlled access to sessions and the list
of sessions for each CdmEngine instance. This guarded against
concurrent access between session management (OpenSession,
CloseSession, etc), periodic timer calls and calls to Decrypt.
The list of sessions and locking was moved to a separate class
CdmSessionMap. This left open the possibility that a session
might be destructed, while being called to decrypt or invoked through the
timer. An attempt was made to add per-session locks in b/73781703
but this was found insufficient.
Per-session locks will be introduced in a future changelist, but for
now the coarser locks will be reintroduced.

[ http://go/wvgerrit/50341 ]
The shared_ptr implementation was taken from a google3 implementation.
Updates to the reference counter needed to be atomic and were
platform dependent in the original code. These were not carried
over to this codebase. Race conditions between calls to decrypt and
the periodic timer, led to incorrect reference count values.
CdmSession objects were then destructed while references to
them still existed. Segfaults occurred when they were referenced.
