We can now launch GL or XV apps in any of the Xephyr screens we want. * hw/kdrive/ephyr/hostx.c,h: (hostx_get_window): (hostx_create_window): make these functions be screen number aware. * hw/kdrive/ephyr/XF86dri.c : fix some compiler warnings. * hw/kdrive/ephyr/ephyrdri.c: (ephyrDRIQueryDirectRenderingCapable), (ephyrDRIOpenConnection), (ephyrDRIAuthConnection), (ephyrDRICloseConnection), (ephyrDRIGetClientDriverName), (ephyrDRICreateContext), (ephyrDRIDestroyContext), (ephyrDRICreateDrawable), (ephyrDRIGetDrawableInfo), (ephyrDRIGetDeviceInfo): in all those functions, don't forward the screen number we receive - from the client - to the host X. We (Xephyr) are always targetting the same X display screen, which is the one Xephyr got launched against. So we enforce that in the code. * hw/kdrive/ephyr/ephyrdriext.c: (EphyrMirrorHostVisuals): make this duplicate the visuals of the host X default screen into a given Xephyr screen. This way we have a chance to update the visuals of all Xephyr screen to make them mirror those of the host X. (many other places): specify screen number where required by the api change in hostx.h. * hw/kdrive/ephyr/ephyrglxext.c: specify screen number where required by the api change in hostx.h * hw/kdrive/ephyr/ephyrhostglx.c: don't forward the screen number we receive - from the client - to the host X. We (Xephyr) are always targetting the same X display screen, which is the one Xephyr got launched against. So we enforce that in the code. * hw/kdrive/ephyr/ephyrhostvideo.c,h: take in account the screen number received from the client app. This is useful to know on which Xephyr screen we need to display video stuff. * hw/kdrive/ephyr/ephyrvideo.c: update this to reflect the API change in hw/kdrive/ephyr/ephyrhostvideo.h. (ephyrSetPortAttribute): when parameters are not valid - they exceed their validity range - send them to the host anyway and do not return an error to clients. Some host expose buggy validity range, so rejecting client for that is too harsh.
