Maintain a small cache of pixmaps to hold SolidFill pictures. Currently
we create a pixmap the size of the damaged region and fill that using
pixman before downloading it to the GPU and compositing. Needless to say
this is extremely expensive compared to simply emitting the solid
colour. To mitigate this cost, we maintain a small cache of 1x1R
pictures which is recognised by the driver as being a solid, but at the
very least is maintained as a GPU ready pixmap.
This gives a good boost to cairo-xcb (which uses solid fills) on a gm45:
Before:
gnome-terminal-vim: 41.9s
After:
gnome-terminal-vim: 31.7s
Compare with using a cache of 1x1R pixmaps in cairo-xcb:
gnome-terminal-vim: 31.6s

This should restore the previous level of synchronisation between
textures and pixmaps, but *does not* guarantee that a texture will be
flushed before use. tfp should be fixed so that the ddx can submit the
batch if required to flush the pixmap.
A side-effect of this patch is to rename intel_batch_flush() to
intel_batch_submit() to reduce the confusion of executing a batch buffer
with that of emitting a MI_FLUSH.
Should fix the remaining rendering corruption involving tfp [inc compiz]:

If we wedge the GPU then we will return -EIO for the current batch and
then attempt to reset the GPU. Meanwhile the X server detects the error,
throws a FatalError and to all intents and purposes appears to crash to
the user - whereas before it often just appeared to momentarily freeze.
Of course, on older hardware the server remains frozen until we can find
a way to reset those GPUs at runtime.

Around a call to uxa_put_image() it is possible to mix both accelerated
and fallback paths, with the fallback code making the presumed
optimisation of only trying to call uxa_prepare_access() once. This
fails if the accelerated path also uses prepare/finish access on the
same drawable and then later fallback to the fallback path. This can
happen currently if an error is reported whilst attempting to accelerate
PutImage.

The kernel will only emit a flush iff the buffer is currently owned by
the GPU. Instead of presuming that the kernel must emit a flush, it is
safer to assume that it does not and so cannot mapping the buffer on to
the CPU as a synchronisation point. The most obvious counter-example is
when we map the same buffer twice without using it in a batch.

These files have been dropped from the generated tar file since the
removal of UMS support. However, the bios_reader code still includes
these, so "make distcheck" fails unless these are distributed.
There's probably a cleaner fix possible, but this at least fixes the
build so that the snapshot can be pushed out.
On older chipsets (i.e. pre-i965) tiling is very restrictive and imposes
severe size and alignment constraints. Combine that with relatively
small apertures and it is very easy to create a batch buffer that
cannot be mapped into the aperture (but would otherwise fit based purely
on total object size). To prevent this we need to not use tiling for large
buffers (the very same buffers where tiling would be of most benefit!).

[UXA] XPutImage performance regression

Using the particular synthetic benchmark in question on a g45:
Before:
9542.910448 Ops/s; put composition (!); 15x15
5623.271889 Ops/s; put composition (!); 75x75

After:
40173.865300 Ops/s; put composition (!); 15x15

4794.368601 Ops/s; put composition (!); 250x250
which while not stellar performance is at least an improvement. As
anticipated this has little impact on the non-fallback RENDER paths, for
instance the current cairo-xlib backend is unaffected by this change.

Instead of allocating and utilising the texture samplers for 1x1R
solid sources and masks we can simply use the default diffuse and
specular colour channels and adjust the fragment shader appropriately.
The big advantage is the reduction in size of batches which should give
a good boost to glyph performance, irrespective of the additional boost
from using simpler shaders.
However, the motivating factor behind the switch is that our use of 1x1
textures turns out to be buggy...
