Enforce OEMCrypto insufficient resources error reporting in CDM tests.
In addition, when CreateNew/LoadUsageEntry fails with OEMCrypto
insufficient resources error, delete a random usage entry
and retry. The current behavior evicts low index entries
from the usage table, which was a crude attempt to emulate a LRU.
This was deficient as, on occasion, it will result in the deletion
of a recently added usage entry.

google::protobuf::uint64 is changing from unsigned long long to
uint64_t, which is sometimes unsigned long long and sometimes
unsigned long. Add a SetValue specialization for unsigned long.
Mark both the unsigned long and unsigned long long specializations
as sometimes unused, they will be unused if uint64_t is the other.

If OEMCrypto runs out of space in the usage table header+entries adding
a new license or loading/using an existing one might fail. This CL makes
two modifications to handle this scenario.
* OEMCrypto_ERROR_INSUFFICIENT_RESOURCES will be returned from
OEMCrypto_CreateNewUsageEntry or OEMCrypto_LoadUsageEntry. An attempt
will be made to release a LRU entry from the usage table and retry
the operation. This may be retried 3 times unless success
occurs earlier.
* On initialization, the usage table header is loaded. If there are more than
the minimum number of usage entries (200), an attempt is made to
add a usage entry. If this fails, we are likely in an unrecoverable
state. We then delete all offline licenses, usage information and
recreate the usage table header. This will allow future playback
attempts to succeed and offline licenses to be able to be downloaded
but will lose all current offline licenses and secure stops.

This CL modifies the oemcrypto test TwoHundredEntries so that it
attempts to create more than 200 entries. A device is allowed to fail
when such an attempt is made, but it must return an insufficient
resources error.
The test then verifies that each of the entries that were succesfully
created can be used to reload its license and the keys can be used for
decryption.
It then shrinks the usage table header, and verifies that the
remaining licenses can still be used for decryption.

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.

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.
