Allows the WV extractor to run in a mode that is compatible with
the DRM CryptoPlugin HAL API, where decryption is deferred
until the encrypted data is sent through the CryptoPlugin to
the codec.
This patch does:
(1) Adds a flag mCryptoPluginMode that controls this behavior
[Note: need framework support to enable/disable this]
(2) Accumulates information in track metadata to delineate
crypto unit boundaries for the CryptoPlugin
