Currently drm-layer supports HDCP1.4 using connector property: Content Protection. This property if available for a platform, can be read and set for requesting content-protection. Also, the patch series [1] adds HDCP2.2 support in drm, and patch [2] adds support to send udev events for change in connector properties, made by the kernel. This patch adds these HDCP connector properties in weston, and exposes the content-protection support to the client for drm-backend. It adds the enums to represent 'Content Protection' and 'Content Type' connector properties exposed by drm layer. It adds a member 'protection' in drm_output_state, to store the desired protection from the weston_output in the drm-backend output-repaint cycle. This is then used to write the HDCP connector properties for the drm_heads attached to the drm_output. The kernel sends uevents to the user-space for any change made by it in the "Content Protection" connector property. No event is sent in case of change in the property made by the user-space. It means, when there is a change of the property value from "DESIRED" to "ENABLE" i.e. successful authentication by the kernel, a uevent will be generated, but in case of userspace requesting for disabling the protection by writing "UNDESIRED" into the property, no uevent will be generated. This patch also adds support for handling new udev events for HDCP connector property changes. Any such change, triggers change in the weston_head's current_protection.
