Drive-by comment: for all of the cases where WIDEVINE_CDM_AVAILABLE was checked
and now ENABLE_WIDEVINE is checked, it should be possible to remove
widevine_cdm_version.h, no?

This is true, but my attempt resulted in a very large, very fragile CL. I'll
split up that work in separate CLs.

 
 namespace chromecast {
 namespace media {
 
 #if defined(PLAYREADY_CDM_AVAILABLE)
 const char kChromecastPlayreadyKeySystem[] = "com.chromecast.playready";
 #endif  // defined(PLAYREADY_CDM_AVAILABLE)
 
 CastKeySystem GetKeySystemByName(const std::string& key_system_name) {
-#if defined(WIDEVINE_CDM_AVAILABLE)
+#if defined(ENABLE_WIDEVINE)
   if (key_system_name.compare(kWidevineKeySystem) == 0) {
     return KEY_SYSTEM_WIDEVINE;
   }
-#endif  // defined(WIDEVINE_CDM_AVAILABLE)
+#endif  // defined(ENABLE_WIDEVINE)
 
 #if defined(PLAYREADY_CDM_AVAILABLE)
   if (key_system_name.compare(kChromecastPlayreadyKeySystem) == 0) {
     return KEY_SYSTEM_PLAYREADY;
   }
 #endif  // defined(PLAYREADY_CDM_AVAILABLE)
 
   if (key_system_name.compare(::media::kClearKey) == 0) {
     return KEY_SYSTEM_CLEAR_KEY;
   }
 
   return GetPlatformKeySystemByName(key_system_name);
 }
