By using the prepare read code properly we can do wayland dispatch of
multiple queues in multiple threads. I'm not advocating we ever do so,
but if a library (perhaps a gl implementation) wants to dispatch its own
queue, and that happens in a separate thread from our event loop, we
probably don't want the world to explode.

Summary:
There's no benefit to generating ids instead of just using the
Ecore_Wl2_Window pointer in events.
This has the added benefit of working around a really nasty hash collision
bug when multiple ecore_evas engines are used at once.

Clean up various places where we do flushes that we don't need to
because some immediately following action is going to cause a flush.
Also fix places where we flush without actually doing anything.
in the case where a connection was not actively rendering, there was nothing
which would trigger a display flush, leading to applications potentially
deadlocking
@fix
We use immediate mode dmabuf creation at runtime, but this can result in
clients being killed with no option to fallback if the buffers can't be
consumed by the compositor.
This test should catch when a system can allocate a dmabuf buffer and the
compositor claims to accept dmabuf, but the buffer can't actually be used
for whatever reason. We'll then use wl_shm at runtime instead of dmabuf.
There are some binds at startup that result in additional information
being sent, so we may need to call wl_display_sync() multiple times, and
only send the client a SYNC_DONE event when the final one completes.
We need at least version 2 for create_immed, so don't even bind the
global if it's useless to us.
This will also stop us from trying to use dmabuf (and getting killed by
the compositor) on older compositors that don't support the version we
need - we'll just use wl_shm instead when this pointer is NULL.
Flushing should be done where it's needed now, but we still
need the rest of the idle handler as something like mesa may
have dispatched its queue, which reads all the pending wayland
events. In that case we have events to process but the fd will
not poll readable.
@fix T6250
We do flushes when we need them now, so we don't need this somewhat
non deterministic flush mechanism anymore.
Anything that breaks as a result of this should be fixable by adding an
ecore_wl2_display_flush() somewhere appropriate.
If wl_display_flush() returns a non negative number it was successful,
so we should disable the write handler then. We were theoretically always
doing an extra flush on an empty buffer.
This is mostly cosmetic as that's not a costly operation.
