2018-11-13backend/x11: Rename xcb_conn to xcbScott Anderson
When the Xlib connection is removed, this _conn suffix is going to be pointless. I'm removing this preemtively for that.

This prevents some annoying issues when e.g. not including wlr/config.h or making a typo in the guard name.
2018-11-11backend/wayland: handle WL_EVENT_WRITABLE for Wayland socketemersion
We need to flush when the connection is writable again. This is important in case the write buffer becomes full. This is also what Weston does [1]. [1]: https://gitlab.freedesktop.org/wayland/weston/blob/master/libweston/compositor-wayland.c#L2593
2018-11-11backend/wayland: Make header order consistentScott Anderson
2018-11-11backend/wayland: Move initilisation code earlierScott Anderson
The renderer redesign is going to need the render fd before the backend is fully started, so we have to move the wl registry code to when the backend is created instead of when it is started. We also need to stash the wl_keyboard and emit it to library users later, once they've added their listeners and started the backend.
2018-11-11backend/wayland: Use specific wl_global versionsScott Anderson
Explicitly use the version we support instead of accepting the compositor's version.
2018-11-11backend/wayland: Move registry into backendScott Anderson
Registry was a very small file, and is heavily related to the backend, so there is not point in keeping them separate.

This should be set to EGL_OPENGL_ES2_BIT. Also fixes EGL config attributes in the headless and X11 backends.
2018-11-04backend/drm: specify minimum config attributesemersion
Since the format used by DRM is GBM_FORMAT_ARGB8888, we need at least a R, G, B and A channel.

backend/drm: fix frame scheduling on secondary GPUs
2018-10-29backend/drm: fix frame scheduling on secondary GPUsemersion
There was a missing copy_drm_surface_mgpu call in drm_connector_schedule_frame so we asked for a pageflip with an unknown BO, resulting in ENOENT. Additionally, this commit makes schedule_frame return a bool indicating failures. This allows schedule_frame_handle_idle_timer to only set frame_pending to true if a frame has been successfully scheduled. Thus, if a pageflip fails, rendering won't be blocked forever anymore. In case a pageflip is already pending, true is returned because a frame has already been scheduled and will be sent sometime soon.
2018-10-28backend/drm: add WLR_DRM_NO_ATOMIC_GAMMA env variableemersion
This allows the legacy interface to be used instead of atomic if needed. This is a workaround to make some Intel GPUs work (if this variable is unset) as well as to make some AMD GPUs work (if this variable is set).

2018-10-09backend/drm: don't reset conn->pageflip_pending in drm_connector_cleanupemersion
If a pageflip is pending before cleanup, it's still pending after. This is used line 1177: drm_connector_cleanup is called and conn->pageflip_pending is checked afterwards. Fixes #1297

2018-10-09output: remove idle_frame event source when destroying outputemersion
This prevents the idle event to be activated on a destroyed output. This also makes the backend responsible for free-ing modes, as it is the one allocating them and adding them to the list. Note that the DRM backend (the only one using modes) already frees them.

2018-10-05output: don't trigger a frame immediately in schedule_frameemersion
This desynchronizes our rendering loop with the vblank cycle. In case a compositor doesn't swap buffers but schedules a frame, emitting a frame event immediately enters a busy-loop. Instead, ask the backend to send a frame when appropriate. On Wayland we can just register a frame callback on our surface. On DRM we can do a no-op pageflip. Fixes #617 Fixes swaywm/sway#2748

2018-09-28backend/drm: don't free connector immediatelyemersion
When a pageflip is pending, we'll get a DRM event for the connector in the future. We don't want to free the connector immediately otherwise we'll use-after-free in the pageflip handler. This commit adds a new state, "DISAPPEARED". This asks the pageflip handler to destroy the output after it's done pageflipping.
2018-09-24Rework session handlingnyorain
Sessions can now be retrieved from a backend in a more general manner. Multi-backend gets back its `session` field that contains the session if one was created, removing the interfacing from multi backend with the drm backend directly. This adds the possibility to use sessions even without the drm backend. It additionally fixes the bug that 2 session objects got created when WLR_BACKENDS were set to "libinput,drm". To allow vt switching without drm backend (and drm fd) on logind, start listening to PropertiesChanged signals from dbus and parse the session "Active" property when no master fd was created (this does not change current drm backend behaviour in any way).

2018-09-15backend/drm: steal CRTCs from disabled outputsemersion
This commit allows outputs that need a CRTC to steal it from user-disabled outputs. Note that in the case there are enough CRTCs, disabled outputs don't loose it (so there's no modeset and plane initialization needed after DPMS). CRTC allocation still prefers to keep the old configuration, even if that means allocating an extra CRTC to a disabled output. CRTC reallocation now happen when enabling/disabling an output as well as when trying to modeset. When enabling an output without a CRTC, we realloc to try to steal a CRTC from a disabled output (that doesn't really need the CRTC). When disabling an output, we try to give our CRTC to an output that needs one. Modesetting is similar to enabling. A new DRM connector field has been added: `desired_enabled`. Outputs without CRTCs get automatically disabled. This field keeps track of the state desired by the user, allowing to automatically re-enable outputs when a CRTC becomes free. This required some changes to the allocation algorithm. Previously, the algorithm tried to keep the previous configuration even if a new configuration with a better score was possible (it only changed configuration when the old one didn't work anymore). This is now changed and the old configuration (still preferred) is only retained without considering new possibilities when it's perfect (all outputs have CRTCs). User-disabled outputs now have `possible_crtcs` set to 0, meaning they can only retain a previous CRTC (not acquire a new one). The allocation algorithm has been updated to do not bump the score when assigning a CRTC to a disabled output.
