[ Merge of http://go/wvgerrit/19901 ] Protections schemes are specified using a 4CC code {"cbc1", "cbcs", "cenc", "cens"}. A host to network conversion was performed when the PSSH was created and inserted into the license request. A reverse conversion was performed when the code was extracted from the license response. These conversions are problematic if the PSSH is created externally and passed into mediaDrm. To address this, the conversions have been removed and allow protobuf to handle byte ordering. For backward compatibility we allow codes in either ordering. b/30713238 Change-Id: I721b375e446526e544856759cada76a1fa6c7be5
