The pointer grab mecanism had a few inconsistencies in its behavior when
a grab is set or unset. THis commit uniformizes the behavior, and also
introduces a synthetic motion event when the grab is set, allowing the
newly set grab to change the focus or the pointer location if needed.
Also adjust the DnDGrab, as well as the resize and move grabs from anvil
to unset the focus while they are active, matching weston's behavior.
Some events (especially from xinput) cannot be cleanly mapped to a window.
Instead of requiring every event to come with a `Window` reference, move
the window into those events, that have one.
The current code always acquires the buffer it just submitted,
which results in always rendering to a buffer with age "1", although
its contents are older, because the currently held buffer is already
submitted, just not to the swapchain. When it finally is submitted
its age is again set to 1, the other gets its correct age (but too late)
and the circle is repeated again. So lets fix that.
Refactors the `X11Surface` to use the `Swapchain` internally,
which gives us a buffer age implemenation, which we can then use
to change the `Present` struct of the X11 backend to provide age
values to the user.
This change also merged the `Present` struct into the surface
because submits should now happen explicitly via a new `submit`-call
instead of being submitted implicitly on drop.
This allows the buffer to be discarded if rendering fails.
More specifically, this introduces a way to query the available EGL devices on a system, `EGLDevices::enumerate`.
Also this introduces a way to get the `EGLDevice` used by an `EGLDisplay`, `EGLDevice::device_for_display`

Currently keycodes are always converted using xkbcommons
`State::key_get_one_sym` function. This may be not what the compositor
wants, e.g. if it represents keybindings with explicit modifiers.
Applying Shift in this case changes the sym, making it necessary for
the compositor to *undo* this transformation, which is hard or even
impossible and very unnecessary, when we have all the necessary
information in smithay.
Therefor this commit replaces the `Keysym` argument of the filter
closure with a `KeysymHandle`, which allows for different variants of
keysyms to be received. Modified (as previously), unmodified or even
as a raw keycode.
