3f821b291e modesetting: get more values from the fallback cursor probe 
The space needed to store these extra values is at worst a few dozen bytes.
In exchange for these, larger cursors glyphs can use a more optimal cursor size.

7d8f084fbf dri: use static struct init on declaration & drop useless assignments 
Make the code a bit easier to read by using initialization of the reply
structs, at the point of declaration. Most of them aren't written to later,
just passed into WriteReplyToClient(). Also dropping some useless zero
assignments (struct initializers automatically zero-out unmentioned fields).

03fa63778b modesetting: fix shared pixmap dmabuf fd leakage 
After the dmabuf fd exported by another screen is imported to a pixmap,
the pixmap holds a reference for the buffer, thus the FD itself finished
its job and needs to be closed to prevent a stale reference to the
buffer.

b7e9544318 Xext: xvmc: drop dead SHM code path 
Xvmc isn't using SHM for over 20 years now. There's still a code path for it
that could be enabled explicitly by manually setting HAS_XVMCSHM, but no
indication whatsoever that this ever has been done.

Considering that Xvmc in general already is obsolete for very long time now,
we can safely assume this code path is really dead and can be removed.
