When enabling or disabling an extension which is not known to the
Xserver, it will log an error message and list the extensions it knows
about.
That clutters the logs when the Xserver is Xwayland spawned by the
Wayland compositor who doesn't actually know the list of extensions
enabled at build time in the Xserver.
Considering that disabling a non-existing extension is a no-op anyway,
list all the extensions available only when attempting to enable an
extension which the Xserver doesn't know about.

This is useful for mock input drivers that control the server in

thread than processing, it's otherwise impossible for the driver to

The masks we end up building will occupy all 32 bits of an unsigned int,
which means we had better build the shifts out of unsigned ints, because
left-shifting a signed int all the way into the sign bit is undefined.
As discussed in issue #829 the "mi: Shortcut miDoCopy/miCopyArea based
on clipList" change leads to pointer-trails (area under pointer not
restored when it moves) when using a software cursor.
Checking pGC->pCompositeClip instead of pDstDrawable->clipList fixes
this problem.

miHandleExposures does two things: computes the region for which to
generate expose events, and (if the destination is a window) paints the
exposed regions with the background. The bit of this conditional we're
deleting here asserts that the source is either a pixmap or a window
without backing store. The only other possibility is a window _with_
backing store. In the old backing store implementation, this was where
you would recover bits from backing store. Since our "backing store" is
the redirected window pixmap, we know we've already copied all we could,
because CopyArea had already seen the entire window pixmap. So now in
that third case, we are still drawing to a pixmap (so there's no
background to paint) and we are still not generating events, so we can
exit early.
The comment above the function about recovering bits from backing store
is clearly misleading, so delete that too.
This is maybe one more comparison, but it catches FullyObscured windows
slightly earlier, so it's kind of a wash. The important thing is this
allows for paintable but unmapped windows, which will have non-empty
clipList.
Both because extension names are inconsistently capitalized on the wire,
and because the table we're walking spells it COMPOSITE not Composite.
The latter is certainly also a bug, but there's no reason for us to be
that strict.

This avoids recomputing the span data for every dash. x11perf thinks
this is a pretty modest speedup:
832919.4 840471.1 ( 1.009) 100-pixel dashed ellipse
672353.1 680652.2 ( 1.012) 100-pixel double-dashed ellipse
13748.9 24287.9 ( 1.767) 100-pixel wide dashed ellipse
9236.3 21298.2 ( 2.306) 100-pixel wide double-dashed ellipse
But part of the reason it's so modest there is that the arcs are
relatively small (100 pixel diameter at line width 10, so ~6000 pixels)
and the dashes relatively large (30 on 20 off so ~6 dashes per
quadrant).
With larger arcs and finer dashes this is much more impressive. A fairly
trivial testcase of a single 15000x13000 arc with the default {2, 2}
dash pattern drops from ~3500 milliseconds to 10 milliseconds.
