This patch addresses the case where we failed to allocate 'wdata' and
were calling free(ee) before going to an error handler. For the fix,
just don't free(ee) here and let the error handling do it's job.

Coverity reports an error handling issue here as we are not checking
the return value of evas_engine_info_set, so check that return and

Coverity reports that accessing 'einfo' here is a NULL pointer
dereference. evas_engine_info_get can return NULL, so we should be
checking for a valid return before trying to use it.

as per mailing list discussion about dropping xcb support now. it
hasn't been complete for a long time, thus not recommented for being
turned on. as we are moving to a wayland world xcbmakes even less
sense. as agreed, time to clean up a bit and remove a distraction as
well as not well tested code. this also updates po's too.
@feature
draw_frame is a legacy feature that draws a very ugly window border
with a white rect and a black text as title bar. This could be
used in wayland when using only the ecore_evas APIs, rather than
elm_win.
Note that the API ecore_evas_draw_frame_set() can not possibly work
as the flag is checked when the ecore_evas is created, so changing
the flag has no effect on existing windows.
Finally bring these together as much as possible to avoid future
diversions when bugs are only fixed in one or the other.
There are functional changes - state tracking for client side effects is
now added to the shm engine, some bug fixes for the egl engine have been
brought to the shm engine.
Brings resize code into the common implementation - there is a functional
change. There appears to have been a bug in the egl resize where it
used the same w, h order for portrait evases as for landscape. This was
fixed in shm. I've used the shm variant for the common code.
Moves transparent set into the common implementation - there is a
functional change here - the egl engine now calls transparent_set in
render_updates like the shm engine.
It is probable the this was the intended behaviour all along.
Moves alpha set into the common implementation - there is a functional
change here - the egl engine now calls alpha_do in render_updates like
the shm engine.
It is probable that this was the intended behaviour all along.
These engines are incredibly similar - by sharing the same engine info
structure we'll be able to simplify the wayland ecore_evas bits and
make them much more maintainable.
So when mouse / keyboard are present or not it will
generate events.
ecore_evas/wayland will handle that creating or
deleting evas devices for each one (seat device
will be used as parent).
Create or delete evas_devices with class EVAS_DEVICE_CLASS_SEAT
for seats on each ecore_evas created so far.
Initially it's named considering its Wayland id.
Summary:
This change removes the necessity to link EFL against the libvncserver

One deadlock and one segfault.
Patch 1:
Software X11 Evas Engine: Fix deadlock
Summary:
The patch bc6e8d2692 introduced a callback responsible to notify the pixels
that were sent to the X server. Since all EFL rendering is done by another
thread, the callback should be called from the main thread context.
To achieve this behaviour evas_software_x11_region_push_hook_call()
was using ecore_thread_main_loop_begin(), which may cause deadlocks, since
evas mainloop waits for the render thread and the render thread waits
the mainloop.
In order to fix this problem, the function
ecore_main_loop_thread_safe_call_async() will be used to
schedule the callback to run in the main loop context.
Since a callback is schedule to run in async manner, the pixels that
were sent to the X server must not be deleted until the user is informed.
In order to avoid more mallocs(), this patch adds the support for refcounts to the
X_Output_Buffer and Xcb_Output_Buffer.
Patch 2:
Ecore_Evas VNC: Use the image size to create the buffer.
In same cases they may differ and may lead to a segfault, since
memcpy() causes a buffer overrun.

If we set a frame callback on a window with no shell surface (ie: and unmapped
window), the frame callback will never fire. This was preventing some
applications like rage from ever posting a frame.
this fixes intitial iconic state for x11 as demonstrated by
terminology -I
but enlightenment is broken though... xterm -iconic also shows the
same break with a black window.
@fix
so we handled override cases and set withdrawn to false on show, but
when normally managed it might be nicer to wait for a state change via
the wm state property to know we are "normal"
this should fix T4699

This reverts commit 2c736adc87.
well that was totally unexpected. - efl app windows dont show at all..
wtf? this should not have affected that at all..

Summary:
It should be evas_device_add_full() in order to follow the EFL
name pattern.

This patch adds the support for Ecore events from a remove
VNC client. Every time it happens a VNC mouse move/click/wheel or a
VNC keyboard event an Ecore event event will be created and dispatched.
Add a function for ecore_evas_drm to call after a page flip happens so
ecore_drm2 can track busy status for fbs itself (including for the fb
that's currently being flipped to scanout)
Also, call the completion function from ecore_evas_drm
