6a1f050ffc Update Widevine Copyright header for core CDM
[ Merge of http://go/wvgerrit/108064 ]

The Widevine License Agreement has been renamed to use inclusive
language. This covers files in the core directory.

bbe9f6afc4 Add ATSC support - part 1
[ Merge of http://go/wvgerrit/100864 and http://go/ag/10704773 ]

ATSC 3.0 allows for licenses to be downloaded OTA and are tied to
a DRM certificate that may be shared across apps. The provisioning
process for ATSC may happen at the factory or during an OS update.

This contrasts from the regular OTT model, which requires that
provisioning and license download have an uplink as well as a
downlink connection.

This adds support for the ATSC mode property. ATSC mode can only be
set (or unset) before sessions are opened. Once the CDM identifier is
set/sealed, requests to modify the ATSC mode will be rejected.

If one needs to open sessions with both ATSC mode and regular (non-ATSC)
mode, separate MediaDrm objects will need to be created. The default
mode is to not use ATSC.

Enable ATSC mode by calling
  mediaDrm.setPropertyString("atscMode", "enable")

Disable ATSC mode by calling
  mediaDrm.setPropertyString("atscMode", "disable")

Provisioning and unprovisioning requests for ATSC will be rejected as
certificates will be retrieved by the ATSC service.

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
