As we only use the glyph cache for small glyphs, those large than 32x32
will first be copied to a bo and used as a mask in a composite
operation. We can avoid the allocation and upload per use by allocating
a bo for the over-sized glyph from the start. As the glyph is large
anyway, the excess memory allocation is less significant.
Using normal font sizes, firefox shows no change - as expected. However,
using the 36 font size traces, we see around a 10% improvement on g45.

This reverts commit 6d50553e8f.
Now we have taught the fallback path not to infinitely recurse,
re-enable the accelerated path for ShmPutImage and friends.
In order to avoid an infinite recursion after enabling CopyArea to use
the put_image acceleration to either stream a blit or to copy in-place,
we cannot call CopyArea from put_image for the fallback path. Instead,
we can simply call pixman_blt directly, which coincidentally is a tiny
bit faster.

This slighlty improves xrender performance on fence reg starved
i8xx hw.
I've also changed a few function calls to the new names from the
compat ones while looking at the code.
The i915 textured video path is not converted because atm the xv
code does not use tiled surfaces.

Often, for example in the fallback for ShmPutImage, we will attempt to
use uxa_copy_area() copying to a normal pixmap from a memory buffer.
This triggers a fallback, and maps the destination pixmap back into the
GTT. The accelerated put_image path will attempt to stream a blit to the
destination pixmap if it is currently active, avoiding the stall.
We appear to have a confusion of stride in terms of pixels, pitch in
terms of bytes and the actual width of the surface.
i830_pad_drawable_width() appears to be operating aligning *pixels* to a
64 pixel boundary and has never used the chars-per-pixel causing
considerable confusion in its callers. Remove the parameter and ensure
that the callers are expecting a value in pixels returned, multiplying
by cpp where necessary to get the pitch.

In my recent fix for the chroma pitch for i915 xvmc I've forgotten about
i965 class hw. For videos with a non-even sized stride (measured in dwords)
the chroma pitch was internally incosistent and one dword off.
Fix this by using pitch2 for the chroma pitch in i965 textured video like
everywhere else.

And kill all the static structures. This way it's clearer what's

Doing the same with the i965 code will allow us to share the
create_context function.
src/i915_hwmc.h is now almost empty. Move the last #defines to
src/xvmv/i915_xvmc.c where they are actually used and delete the
file.
Also rename the ddx context struct to something sane.

Pauli pointed out that we take a ref on the front buffer when exchanging
but forget to release it. The ref is necessary since the set functions
will drop refs as necessary, but once we set the front buffer to point
at the back pixmap, we ned to release our private ref again, or we'll
leak buffers.

On memory constrained hardware, tiling is vital for good performance as
it minimizes cache misses. The downside is that for older hardware
(which often suffers from the lack of bandwidth) requires the use of
fences for many operations, which are in short supply and so may cause
shorter batchbuffers. However our batch buffers are typically short and
so this is unlikely to be a concern and not affect the performance wins.
A quick bit of testing suggests the effect is inconclusive on
firefox/i945:
linear tiled
xcb 205.470 206.219
xcb-render-0.0 404.704 388.413
xlib 166.410 170.805
A secondary effect of the patch is to workaround a G31 specific hang
when attempting to use linear 2048x2048 surfaces. Bonus!
