mesa: rework texture size error checking

There are two aspects to texture image size checking:
1. Are the width, height, depth legal values (not negative, not larger
   than the max size for the mipmap level, etc)?
2. Is the texture just too large to handle?  For example, we might not be
   able to really allocate memory for a 3D texture of maxSize x maxSize x
   maxSize.

Previously, we did (1) via the ctx->Driver.TestProxyTextureImage() hook
but those tests are really device-independent.  Now we do (2) via that
hook since the max texture memory and texture shape are device-dependent.

Also, (1) is now done outside the general texture parameter error checking
functions because of the special interaction with proxy textures.  The
recently introduced PROXY_ERROR token is removed.

i965: Stop putting 8 NOPs after each prorgam.

As far as I can see, the intention of the requirement that we do so is to
prevent instruction prefetch from wandering out into either unmapped memory or
memory with a different caching type, and hanging the chip.  The kernel makes
sure that the page after your BO has a valid page of the same caching type,
which meets this requirement, so there's no need to waste space between our
programs (and in instruction cache) on this.
