The golden render state is constant, but we recreate the batch setting
it up for every new context. If we keep that batch in a volatile cache
we can safely reuse it whenever we need to initialise a new context. We
mark the pages as purgeable and use the shrinker to recover pages from
the batch whenever we face memory pressues, recreating that batch afresh
on the next new context.

Now that we use the same vfuncs for emitting the batch buffer in both
execlists and legacy, the golden render state initialisation is
identical between both.
v2: gcc wants so.ggtt_offset initialised (even though it is not used)

The Golden batch carries 3D state at the beginning so that HW starts with
a known state. It is carried as a binary blob which is auto-generated from
source. The idea was it would be easier to maintain and keep the complexity
out of the kernel which makes sense as we don't really touch it. However if
you really need to update it then you need to update generator source and
keep the binary blob in sync with it.
There is a need to patch this in bxt to send one additional command to enable
a feature. A solution was to patch the binary data with some additional
data structures (included as part of auto-generator source) but it was
unnecessarily complicated.
Chris suggested the idea of having a secondary batch and execute two batch
buffers. It has clear advantages as we needn't touch the base golden batch,
can customize secondary/auxiliary batch depending on Gen and can be carried
in the driver with no dependencies.
This patch adds support for this auxiliary batch which is inserted at the
end of golden batch and is completely independent from it. Thanks to Mika
for the preliminary review.
v2: Strictly conform to the batch size requirements to cover Gen2 and
add comments to clarify overflow check in macro (Chris, Mika).
v3: aux_batch_offset was declared as u64, change it to u32 (Chris)

Updated the two render_state_init() functions to take a request pointer instead
of a ring. This removes their reliance on the OLR.
v2: Rebased to newer tree.

The batchbuffer that sets the render context state is submitted
in a different way, and from different places.
We needed to make both the render state preparation and free functions
outside accesible, and namespace accordingly. This mess is so that all
LR, LRC and Execlists functionality can go together in intel_lrc.c: we
can fix all of this later on, once the interfaces are clear.
v2: Create a separate ctx->rcs_initialized for the Execlists case, as
suggested by Chris Wilson.
Signed-off-by: Oscar Mateo <oscar.mateo@intel.com>
v3: Setup ring status page in lr_context_deferred_create when the
default context is being created. This means that the render state
init for the default context is no longer a special case. Execute
deferred creation of the default context at the end of
logical_ring_init to allow the render state commands to be submitted.
Fix style errors reported by checkpatch. Rebased.
