-Access permission handling Introduce an internal function which allows the desired process to access decryption flow. This new function is just for reference and each OEM manufacturer should implement/replace with their solutions. -New API, getMetadata() This API is for retrieving media metadata from container-based DRM, such as OMA forward-lock content. This API asks DRM agent to retrieve media metadata hiddein inside of DRM special container. -New API, acquireRights() This API wraps acquireDrmInfo() and processDrmInfo(). If DRM agent has valid implementation of both APIs, Application can acquire DrmRights only by calling this API. -Bug fix in event loop of OnInfoListener. Separate OnInfo event loop from mail thread loop so as to avoid the issue that message is not dispatched when mail thread is busy. Changes are made by SEMC and Sony.
