Since we already had to rename some of them, in order to fix name clashes
on win32, it's now time to rename all the remaining ones.
The old ones are still present as define's to the new ones, just for
backwards compatibility.

Windows' native headers using some our RT_* define's names for other things.
Since the naming isn't very nice anyways, introducing some new ones
(X11_RESTYPE_NONE, X11_RESTYPE_FONT, X11_RESTYPE_CURSOR) and define the old
ones as an alias to them, in case some out-of-tree code still uses them.
With thins change, we don't need to be so extremely careful about include
ordering and have explicit #undef's in order to prevent name clashes on
Win32 targets.

It's needed when the surface window is a depth 24 descendant of a depth
32 toplevel window.
xwl_source_validate ensures the toplevel window pixmap has valid
contents when a client reads from it, or when the window hierarchy /
geometry changes. It's never called in the normal fullscreen application
case, so there's no GPU copy overhead with that.

When a present request is received, Xwayland will check if there is an
existing request targeting the same window and msc and scrap the older
request if so. Alas, this does not interact well the older fence-based
or newer syncobj-based synchronization features of the Present
extension.
Since execution of a request may be delayed for an unknown length of
time while waiting for a fence to be signaled, the target msc computed
upon receiving a request may not match the actual msc at which the
request is executed. Therefore, we cannot determine in advance whether a
more recently received request will make an older request redundant.
This change removes the code to scrap pending present requests.
We must also ensure requests are executed in the correct order even if
their fences are signaled out of order. To achieve this, whenever
execution of a request needs to wait for a fence, execution of any
later-received requests will be blocked until the earlier request is
ready. The blocked requests will be added to a list tracked in the
xwl_present_window struct. Once the earlier request's fence is signaled,
any blocked requests will be re-executed.

This protocol allows for explicit synchronization of GPU operations by
Wayland clients and the compositor. Xwayland can make use of this to
ensure any rendering it initiates has completed before the target image
is accessed by the compositor, without having to rely on kernel-level
implicit synchronization.
Furthermore, for X11 clients that also support explicit synchronization
using the mechanisms exposed in the DRI3 and Present extensions, this
Wayland protocol allows us to simply forward the timeline, acquire, and
release points directly to the compositor, ideally avoiding any
premature stalls in the presentation pipeline.
