Merge from Widevine repo of http://go/wvgerrit/46204 Refactor utility code - split the mock, step 1 Merge from Widevine repo of http://go/wvgerrit/46205 Move some OEMCrypto types to common header - split the mock, step 2 Merge from Widevine repo of http://go/wvgerrit/46206 Split mock into two -- step 3 Merge from Widevine repo of http://go/wvgerrit/47460 Split the mock into two -- step 3.5 The CL moves several files used by oemcrypto and cdm into a common subdirectory, so that it may more easily be shared with partners. The CORE_DISALLOW_COPY_AND_ASSIGN macro was moved to its own header in the util/include directory. This CL removes some references to the mock from other code, and puts some constants and types, such as the definition of the keybox, into a header in oemcrypto. Test: tested as part of http://go/ag/4674759 bug: 76393338 Change-Id: I75b4bde7062ed8ee572c97ebc2f4da018f4be0c9
