		* The DRM and Crypto HALs interact with vendor-provided HAL implementations
		* that have DRM-specific capabilities. Since the VTS tests cannot contain
		* DRM-specific functionality, supporting modules are required to enable VTS
		* to validate HAL implementations in a generic way. If the vendor-specific
		* VTS module is not provided for a given drm HAL implementation, only very
		* small subset of functionality can be verified.
		*
		* As an example, a DRM HAL implementation interacts with a DRM-specific
		* license server to obtain licenses for decrypting content. The DRM HAL
		* implementation generates a key request message, delivers it to the server
		* and receives a key response message which is then loaded into the HAL. Once
		* the keys are loaded, the Crypto HAL decryption functionality and performance
		* and other associated APIs can be tested by the common VTS test suite.
		*
		* Vendor-specific VTS modules are shared libraries used by the DRM VTS test.
		* They provide a set of functions to support VTS testing of the DRM HAL module.
		*
		* The modules are placed in a common location on the file system. The VTS test
		* scans through all vendor-provided support libraries and runs the VTS test
		* suite on each library that is found.
		*
		* The vendor-specific module exposes an extern “C” vendorModuleFactory()
		* function that returns a DrmHalVTSVendorModule instance. DrmHalVTSVendorModule
		* instances are versioned, where each version is represented by subclass of
		* DrmHalVTSVendorModule that corresponds to the API version. For example, a
