Thanks to Intel code which I've just stolen pretty much as usual.
This fixes fdo bug 22851 which is a dri1 regression since rewrite.

This makes the miptree rounds up to the near POT for each level for
all radeons, however since mipmaps aren't support with NPOT on previous
radeons this calculation shouldn't cause any problems. If it does
we can just make it r600 only.
I tested a few mipmap demos on r500 and they all seem to work.

Similar to the classic swapbuffer throttling in GL drivers, put an
upper bound on the number of outstanding chunks of rendering the state
tracker can generate -- where calling the block handler denotes a
chunk.
Currently that number is set at around 4 "chunks", but could be
tweaked up or down. If a better measure for the amount of outstanding
rendering is found, that would be fine too.
As it stands, this improves interactivity by preventing the X server
from queueing up arbitary amounts of rendering.
These currently don't reference any constants. Can add this back
if newer shaders need them, but in the meantime don't create
a new constant buffer every time we do a blit.
The two users of composite (Composite and Solid) now call a new
xorg_composite_done() from their Done functions, while CopyDone
is directly implemented on top of xorg_renderer.c.
It would be nice if these drivers built under the linux-debug header
so that these types of interface changes can be minimally propogated
into those drivers by people without the hardware. They don't have to
generate a working driver -- though a command-dumping winsys would be
an excellent for regression checking.
Drop anonymous 'Extended' fields, have every optional token named
explicitly in its parent. Eg. there is now an Instruction.Label flag,
etc.
Drop destination modifiers and other functionality which cannot be
generated by tgsi_ureg.c, which is now the primary way of creating
shaders.
Pull source modifiers into the source register token, drop the second
negate flag. The source register token is now full - if we need to
expand it, probably best to move all of the modifiers to a new token
and have a single flag for it.
