If we have a separate render resource, it may contain more up-to-date
data than what is available in the base resource, so we need to retarget
the transfer to this resource. As the most likely reason for the
existence of the render resource is a multi-tiled render layout we need
to allow this transfer to go through the resolve/blit copy path, as we
can't de-/tile those layouts in software.

To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium. Since u_format used
util_copy_rect(), I moved that in there, too.
I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.

This allows a write to proceed to an uninitialized part of a buffer
even when the GPU is using the previously-initialized portions.
Such a situation can be triggered with the following API usage example:
glBufferSubData(..., offset, size, data1);
glDrawArrays(...);
// append new vertex data
glBufferSubData(..., offset+size, size, data2);
glDrawArrays(...);
Same is done for freedreno, nouveau and radeon.

The rs alignment doesn't have to be multiplied by # of pixel pipes.
This works on GC2000 which doesn't have the SINGLE_BUFFER feature.
This fixes some cubemaps (NPOT / small mipmap levels) because aligning by 8
breaks the expected alignment of 4 for tiled format. We don't want to mess
with the alignment of tiled formats.

Changes from v3 -> v4:
- drop rsc->lock, just use screen->lock for the entire serialization (Marek)
- simplify etna_resource_used() flush condition, which also prevents
potentially flushing resources twice (Marek)
- don't remove resouces from screen->used_resources in

Currently we are blitting the whole resource when the RS is used to
de-/tile a resource. This can be very inefficient for large resources
where the transfer is only changing a small part of the resource
(happens a lot with glTexSubImage2D).
Optimize this by only blitting the tile aligned subregion of the
resource, which the transfer is going to change.

The cpu_fini() call pushes the buffer back into the GPU domain, which needs
to be done for all buffers, not just the ones with CPU written content. The
etnaviv kernel driver currently doesn't validate this, but may start to do
so at a later point in time. If there is a temporary resource the fini needs
to happen before the RS uses this one as the source for the upload.
Also remove an invalid comment about flushing CPU caches, cpu_fini takes
care of everything involved in this.
