Currently if modesetting ever fails to set a hardware cursor it will switch
to using a software cursor and never go back. Change this to only
permanently switch to a software cursor if -ENXIO is returned (which means
hardware cursors not supported), and to otherwise still try a hardware
cursor first every time a new one is set. This is needed because hardware
may be able to handle some cursors in hardware and others not, or virtual
hardware may be able to handle hardware cursors at some times and not
others.
Changes since v1, v2 and v3:
* take into account the switch to load_cursor_argb_check
* keep the permanent software cursor fall-back if -ENXIO is returned
* move parts of v3 into separate patches

There is currently no reliable way to report failure to set a HW
cursor. Still such failures can happen if e.g. the MODE_CURSOR DRM
ioctl fails (which currently happens at least with modesetting on Tegra
for format incompatibility reasons).
As failures are currently handled by setting the HW cursor size to
(0,0), the fallback to SW cursor will not happen until the next time the
cursor changes and xf86CursorSetCursor() is called again. In the
meantime, the cursor will be invisible to the user.
This patch addresses that by adding _xf86CrtcFuncs::set_cursor_check and
_xf86CursorInfoRec::ShowCursorCheck hook variants that return booleans.
This allows to propagate errors up to xf86CursorSetCursor(), which can
then fall back to using the SW cursor immediately.
v5:
- Removed parts of patch already committed as part of 14c21ea1.
- Adjusted code slightly to match surrounding code.
- Effectively reverted af916477 which is made unnecessary by this patch.

ShowCursorCheck(), as instead just changing ShowCursor() to return Bool
should not affect its current callers.

xf86RecolorCursor() may be called directly from XRecolorCursor as well
as from xf86ScreenSetCursor(). In the latter case, the input lock is
already held, but not for the former and so we need to add a wrapper
function that acquires the input lock before performing
xf86RecolorCursor()

The idea here is that the driver might have once been old enough to not
have the driverFunc slot in DriverRec, with the module ABI not having
changed when it was added. That was ages ago, and drivers always declare
themselves with DriverRec not DriverRec1, so uninitialized slots will
simply be zero.

Should you find yourself using a 16bpp display while also using a
compositor, you poor soul, you may find that your GLX applications
behave strangely; in particular, glxgears will be transparent. This is
because it clears to (0,0,0,0) which is transparent if you honor alpha,
and it will choose the synthetic visual because it has the most
available r/g/b bits.
To avoid this, bump synthetic visuals to a higher (less-preferred)
select group. Unless the client explicitly asks for non-zero alpha bits,
this will prefer any rgb565 visual ahead of the argb8888 visual.

glamor_pixmap_ensure_fbo().
On memory pixmaps, the first call will set the FBO and the second one
will fail an assertion in glamor_upload_picture_to_texture() because
the FBO is already set.
Bail out earlier when the mask pixmap is in memory and the hardware
capabilities would require to use two pass, so that the assertion is not
