Alex Dale 1069ae39cc Resize OEMCrypto buffer-based results on success. 
[ Merge of http://go/wvgerrit/151191 ]

Within the CDM and OEMCrypto tests, there were a few OEMCrypto function
calls where the final size of the output buffers were not being
resized.  For several of these functions, an initial call is made with
zero-length output buffers, expecting OEMCrypto to return
ERROR_SHORT_BUFFER; followed by a call with buffers at least as large
as specified by OEMCrypto.  However, for some operations, OEMCrypto
makes an estimate on the final size on the first call, specifying the
exact size only after performing the operations.

This is the case for the wrapped key returned by
OEMCrypto_LoadProvisioning().  The provisioning response contains a
padded + encrypted DRM key.  OEMCrypto does not know the actual size
of the key until decrypted, and the actual DRM key might be smaller.

There was a OEMCrypto test for OEMCrypto_BuildInformation() which
was enforcing the wrong behaviour.  This has been updated.

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:
