John W. Bruce e10ac3b465 Finer-Grained OEMCrypto Locking

(This is a merge of http://go/wvgerrit/72867)

This patch replaces the previous static std::mutexes in CryptoSession
with shared_mutexes, allowing multiple readers to access the resources
they protect. For the shared fields, this means only Initialize(),
Terminate(), and the code that sets up the usage table headers needs
exclusive access. All other CryptoSession code is able to read these
fields in parallel.

For OEMCrypto, the static OEMCrypto lock is joined by a per-session
std::mutex, which are used in concert to enforce the OEMCrypto v15
threading guarantees.

On my machine this results in a noticeable increase in performance for
the parallel unit tests.

README

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
