This patch adds support for downloading the Widevine L1 plugin for Windows and WMF. It is disabled by default. It does not integrate utilizing the plugin with our WMF framework. New prefs for the new plugin type include: - media.gmp-widevinecdm-l1.visible - media.gmp-widevinecdm-l1.enabled - media.gmp-widevinecdm-l1.forceInstall All of the above should be flipped to true in order to make Firefox install the plugin. The GMPParent for the plugin can be discovered using SelectPluginForAPI. The API tags are com.widevine.alpha.experiment and com.widevine.alpha.experiment2.
