Not doing so seems to cause lock-ups or rendering problems
on some chips. I think there is an logic issue related to
CB and VGT on some chips. We ran into similar issues in
r600_demo IIRC.
This patch fixes some "implicit declaration of function" compilation
errors/warnings on the new shader code.

Part of this code is disabled since no performance gains
where detected with it enabled.
This code only detects if it is a pixmap that it is
rendering to on the st/xorg DDX since it sets the fake
front to the same handle as front.
When adding a new bitmap to the cache we have to check if the Z value is
changing and flush first if it is.
This is a modified version of a patch from Justin Dou <justin.dou@intel.com>
We do flush for cmd buffer in case there isn't enough space left for whole
rendering operation. This protects dma regions from getting released in middle
of state emit.

This fixes some state atom check functions from returing wrong emit size.
There is emit code cleanup so that emit function selection is done in init
time instead of runtime.

- emit prediction
- fixes to emit_sizes for data
- clean up of excesive use of radeonEnsureCmdBufferSpace

Patch adds prediction functionthat tries to predict emit size to the smallest
possible values that is quarenteed to be higher than worst case scenario in
rendering pipeline.
State emit size prediction code is in place but fix for emit sizes is included
in next patch.

This fixes bug that xdemos/manywin would segfault if it was run with command
./manywin 2. Demo is tring to call glXSwapBuffers while another context was
bind using glXMakeCurrent.
Fix is simple makes drawable and readable persistent untill they change or
context is destroyed.
I found a logic error when same dri context is used for multiple drawables
which caused readable and drawable to fall out of sync in special case. Fix
is simple just updating drawables more often than in original patch.
