GL_APPLE_object_purgeable creates a mechanism for marking OpenGL objects
as "purgeable" so they can be thrown away when system resources become
scarce. It specifically applies to buffer objects, textures, and
renderbuffers.
The intel_buffer_objects.c file provides core functionality for GL
buffer objects, such as MapBufferRange and CopyBufferSubData. Having
texture and renderbuffer functionality in that file is a bit strange.

It moves all sampler view descriptors to a buffer.
It supports partial resource updates and it can also unbind resources
(required for FMASK texturing).
The buffer contains all sampler view descriptors for one shader stage,
represented as an array. On top of that, there are N arrays in the buffer,
which are used to emulate context registers as implemented by the previous
ASICs (each array is a context).
This uses the RCU synchronization approach to avoid read-after-write hazards
as discussed in the thread:
"radeonsi: add FMASK texture binding slots and resource setup"
CP DMA is used to clear the descriptors at context initialization and to copy
the descriptors from one context to the next.
v2: - use PKT3_DMA_DATA on CIK (I'll test CIK later)
- turn the bool CP DMA parameters into self-explanatory flags
- add a nice simple API for packet emission to radeon_winsys.h
- use 256 contexts, 128 causes texture corruption in openarena
It shouldn't be necessary to call radeon_winsys::cs_flush() from
radeonsi_launch_grid(), because the state tracker is responsible for
flushing the pipeline at the appropriate time. The current behavior is
also wrong, because radeonsi_launch_grid() submits packets to the
compute ring, but when the state tracker calls pipe->flush() everything
is submitted to the graphics ring. This has the potential to create a
race condition.
The downside of removing this flush is that the compute dispatch packets
will be sent to the graphics ring rather than the compute ring.
In the future we will need to come up with a way to detect 'compute'
command streams and submit them to the appropriate ring.

Previously, INTEL_DEBUG=bat would dump messages like:
intel_mipmap_tree.c:1643: Batchbuffer flush with 456b used
This only reported the space used for command packets, and didn't
report any information on the space used for indirect state.
Now it dumps:
intel_context.c:366: Batchbuffer flush with 6128b (pkt) + 4288b (state)
= 10416b (31.8%)
This conveniently shows the breakdown of space used for packets vs.
state, as well as the percentage of batchbuffer space.

With this and the next patch, there are only four changes in shader-db:
all a single extra instruction. The code does something like
mov a.w, -b.x
and copy propagation doesn't work because it only handles no-op
swizzles. Seems acceptable, given the known limitation of our copy
propagation.
