Again, last valid address, not first invalid address. Fixes regression
in 255e5be265 that the kernel now catches
and caused piglit draw_elements_base_vertex to fail.
It's the address of the last valid byte, not the address of the first
invalid byte.
This should also fix problems with rendering with the new sanity checks in
the kernel.
This change silenced valgrind warnings but broke progs/tests/drawbuffers.
The problem is we don't know the surface's state when we start caching it
(it may or may not be initialized/cleared/etc). So "clearing" it here was
presumptuous. Leaving the code in place (but disabled) for reference and
when using valgrind.
Fixes bug 24401
Before, if we called glXMakeCurrent() to change a context's window binding
while an FBO was bound, we weren't updating the intel->driDrawable and
intel->driReadDrawable fields. This could cause us to dereference a null
pointer elsewhere.
The non-KMS interface is to blame here. In theory, a proper fix
could be produced that works for the KMS interface only, but it
require cleaning a lot of mess. Easier to just do it right in r300g.

If we deleted a currently bound texture, we were always reverting the texture
binding to the default 1D texture rather than the proper default texture.
The renderType parameter to CreateContext() was never used. Also, it
was often passed as zero. Now when it's zero we check if the context
is RGBA or CI mode and set it accordingly.
Fixes bug 24211.
Once we've freed a miptree, we won't see any more state cache requests
that would hit the things that pointed at it until we've let the miptree
get released back into the BO cache to be reused. By leaving those
surface state and binding table pointers that pointed at it around, we
would end up with up to (500 * texture size) in memory uselessly consumed
by the state cache.

Since sqrt() is basically implemented in terms of RSQ/RCP we'll do a
divide by zero if x=0 and wind up with unpredictable results.
Now use CMP instruction to test for x<=0 and return zero in that case.
