to reduce the call indirections with u_resource_vtbl.
The worst call tree you could get was:
- u_transfer_inline_write_vtbl
- u_default_transfer_inline_write
- u_transfer_map_vtbl
- driver_transfer_map
- u_transfer_unmap_vtbl
- driver_transfer_unmap
That's 6 indirect calls. Some drivers only had 5. The goal is to have
1 indirect call for drivers that care. The resource type can be determined
statically at most call sites.
The new interface is:
pipe_context::buffer_subdata(ctx, resource, usage, offset, size, data)
pipe_context::texture_subdata(ctx, resource, level, usage, box, data,
stride, layer_stride)

Just for consistency. This should have no effect, because OpenGL textures
always go to VRAM.

The whole point of AMD_pinned_memory is that applications don't have to map
buffers via OpenGL - but they're still allowed to, so make sure we don't break
the link between buffer object and user memory unless explicitly instructed
to.

This accomodates a streaming pattern where the discard flag is set when the
application wraps back to the beginning of the buffer.

The fixed alignment of u_upload_mgr will go away.
This is the first step.
The motivation is that one u_upload_mgr can have multiple users,
each allocating from the same buffer, but requiring a different alignment.

DCC is disabled for textures that can be shared as sharing the
DCC buffers has not been implemented yet.

Basically, do the same thing as for buffer_unmap, but use the explicit range
instead. It's for apps which want to map a whole buffer and mark touched
ranges explicitly.

Instead create a staging texture with pipe_buffer_create and
PIPE_USAGE_STAGING.
u_upload_mgr sets the usage of its staging buffer to PIPE_USAGE_STREAM.
But since 150ac07b85 CPU -> GPU streaming buffers
are created in VRAM. Therefore the staging texture (in VRAM) does not offer any
performance improvements for buffer downloads.
