This implements the CDM code changes necessary to take advantage of
Combined Decrypt Calls on OEMCrypto v16. The result of this is that
WVCryptoPlugin is much lighter now because it can pass the full sample
down to the core in one call, but CryptoSession is heavier, as it now
has to handle more complex fallback logic when devices can't handle
multiple subsamples at once.
This patch also removes support for the 'cens' and 'cbc1' schema, which
are being dropped in OEMCrypto v16. This fixes an overflow in the code
for handling those schemas by removing it entirely.
This patch also fixes the "in chunks" legacy decrypt path to use larger
chunk sizes on devices with higher resource rating tiers.

Certain C++11 (and newer) standard library functions and classes which
utilize random number generators require that the random number
generators meet the specifications of C++11's UniformRandomBitGenerator
name requirements. This is especially important as C++17 will remove
support non-compliant alternatives.
This change updates CdmRandomGenerator to meet these requirements.

The primary goal is to replace the use of `rand()` with the random
number generators provided with the C++11 standard.
This simplified generator wraps some of the technical aspects of the
<random> library and provides an interface for uniformly distributed
integers.
As part of the `rand()` purge in the CDM, all uses of the C random int
function in `core()` have been removed. Places that previously used
`rand()` now use `CdmRandom` facilities.

The CE CDM implements the ability to silence all logging with a "silent"
log level. However, under the covers, this assigned a value to g_cutoff
that was not a member of LogPriority, which fails some extremely strict
checks. This patch just adds a matching entry to LogPriority so that
"silent" is now a valid level in that enum.
A previous merge of this change broke builds on Elfin because it uses
stricter compiler settings that rejected the lack of LOG_SILENT in
certain switch statements. I've gone through the codebase and found
every switch on a LogLevel variable and updated it, of which only one
affects the Android build.

We need a reader-writer lock implementation in order to make use of the
new threading guarantees in OEMCrypto v15. However, we do not have
access to an STL reader-writer lock due to only being on C++11. This
patch adds a home-grown reader-writer lock, as well as tests to verify
that its behavior is sound.

The FileSystem interface as it exists expects an Open for a file and
then a Close when finished. However, the Close doesn't delete the file
itself and depending on the platform, the underlying impl_ as well,
leading to a memory leak. To fix this leak as well as harden against
future memory issues, this change refactors the interface to shift away
from raw pointers and towards smart pointers.

The CORE_DISALLOW_COPY_AND_ASSIGN macro was moved to its own header in
