This way, it is possible to identify when a resource is both pending
read and pending write at the same time. Moreover, the status field
can be correctly calculated and updated when necessary.

As long as a resource is pending in any context we must not destroy
it, otherwise we'll hit a classical use-after-free with fireworks.
To avoid this take a reference when the resource is first added to
the pending set and put the reference when no longer pending.

Currently, the screen tracks all resources for all contexts, but this
is not correct. Each context should track the resources it uses. This
also allows a context to detect whether a resource is used by another
context and to notify another context using a resource that the current
context is done using the resource.

The flush callback may be called on the same pipe context, and thus
the same stream, from two different threads of execution. However,
etna_cmd_stream_flush{,2}() must not be called on the same stream
from two different threads of execution as that would mess up the
etna_bo refcounting and likely have other ugly side effects.
Fix this by using a reentrant screen lock around the flush callback.

We were leaking surfaces because the references taken in
etna_set_framebuffer_state weren't being released on context destroy.
Instead of just directly releasing those references in
etna_context_destroy, use the util_copy_framebuffer_state helper.
Take the chance to remove the duplicated buffer references in
compiled_framebuffer_state to avoid confusion.
The leak can be reproduced with a client that continuously creates and

At least GC2000 seems to push some dirt from the PE color cache into
the last bound render target when drawing depth only. Newer cores
seem to behave properly and don't do this, but I have found no way
to fix it on GC2000. Flushes and stalls don't seem to make any
difference.
In order to stop the core from pushing the dirt into a precious real
render target, plug in dummy buffer when rendering without a color
buffer.

The blob does this, as DRAW_INSTANCED can replace fully all the other
draw commands. It is also required to handle integer vertex formats.
The other path is only there for compatibility and might go away (or at
least rot to become buggy due to dis-use) in newer hardware.
As a by-effect this changes the behavior for GC3000-, by no longer using
the index offset for DRAW_INDEXED but instead adding it to INDEX_ADDR.
This should make no difference.

Instead of pipe_index_buffer::offset, pipe_draw_info::start is used.
For indexed indirect draws, pipe_draw_info::start is added to the indirect
start. This is the only case when "start" affects indirect draws.
pipe_draw_info::index is a union. Use either index::resource or
index::user depending on the value of pipe_draw_info::has_user_indices.

This patch adds support for the SINGLE_BUFFER feature on GC3000
GPUs, which allows rendering to a single buffer using multiple pixel
pipes.
This feature is always used when it is available, which means that
multi-tiled formats are no longer being used in that case, and all
buffers will be normal (super)tiled. This mimics the behavior of the
blob on GC3000.
- Because the same format can be used to render to and texture from,
this avoids an extra resolve pass when rendering to texture.
- i.MX6qp includes a PRE which can scan-out directly from tiled formats,
avoiding untiling overhead.
