Instead of copying this memory to driver simplier thing is

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 is a relatively minimal change to adjust all the gallium interfaces
to use bool instead of boolean. I tried to avoid making unrelated
changes inside of drivers to flip boolean -> bool to reduce the risk of
regressions (the compiler will much more easily allow "dirty" values
inside a char-based boolean than a C99 _Bool).

State validation is performed during clear and draw calls. Validation
during clear was still accessing vertex buffer state. When the currently
set vertex buffers are client arrays, this could lead to accessing freed
memory. Such is the case with the VMD application.
Previously, vertex buffer validation depended on a dirty bit or the
draw info indicating an indexed draw. This required special handling for
clears. But, vertex buffer validation still occurred which was unnecessary
and wrong.
Now, only minimal validation is performed during clear, deferring the
remainder to the next draw. And, by setting the dirty bit in swr_draw_vbo
for indexed draws, vertex buffer validation is only dependent upon a
single dirty bit.
This fixes a bug exposed by the VMD application when changing models.

Swr caches fb contents in tiles. Those tiles are stored on a per-context
basis.
When switching contexts that share resources we need to make sure that
the tiles of the old context are being stored and the tiles of the new
context are being invalidated (marked as invalid, hence contents need
to be reloaded).
The context does not get any dirty bits to identify this case. This has
to be, then, coordinated by the resources that are being shared between
the contexts.
Add a "curr_pipe" hook in swr_resource that will allow us to identify a
MakeCurrent of the above form during swr_update_derived(). At that time,
we invalidate the tiles of the new context. The old context, will need to
have already store its tiles by that time, which happens during glFlush().
glFlush() is being called at the beginning of MakeCurrent.
So, the sequence of operations is:
- At the beginning of glXMakeCurrent(), glFlush() will store the tiles
of all bound surfaces of the old context.
- After the store, a fence will guarantee that the all tile store make
it to the surface
- During swr_update_derived(), when we validate the new context, we check
all resources to see what changed, and if so, we invalidate the
current tiles.

The shader that is used to copy vertex data out of the vs/gs shaders to
the user-specified buffer (streamout or SO shader) was not using the
correct offsets.
Adjust the offsets that are used just for the SO shader:
- Make sure that position is handled in the same special way
as in the vs/gs shaders
- Use the correct offset to be passed in the core
- consolidate register slot mapping logic into one function, since it's
been calculated in 2 different places (one for calcuating the slot mask,
and one for the register offsets themselves
Also make room for all attibutes in the backend vertex area.

- trim feState.vsVertexSize
- fix GS interface and incorporate GS while calculating vsVertexSize
Note that vsVertexSize is used in the core as the one parameter that
controls vertex size between all stages, so it has to be adjusted appropriately
for the whole vs/gs/fs pipeline.
Also note that GS and SO is not fully implemented. This will be addressed
later.

If size of client memory copy is too large, don't copy. The draw will
access user-buffer directly and then block. This is faster and more
efficient than queuing many large client draws.
Applications that still use large client arrays benefit from this. VMD
is an example.
The threshold for this path defaults to 32KB. This value can be
overridden by setting environment variable SWR_CLIENT_COPY_LIMIT.
v2: Use #define for default value, rather than hard-coded constant.

Each shader stage state (VS, TS, GS, SO, BE/CLIP) now has a
vertexAttribOffset to specify the offset to the start of the
general attribute section of the incoming verts for that stage.
It is up to the driver to set this up correctly based on the
active stages. All the shader stages use this value instead of
VERTEX_ATTRIB_START_SLOT to offset to the incoming attributes.
Only the vertex shader stage supports dynamic layout output
currently. The other stages continue to expect the output to be
the fixed layout slots as before. Will be enabling GS next.

Consider the following RT attachment order:
1. Attach surfaces attachments 0 & 1, and render with them
2. Detach 0 & 1
3. Re-attach 0 & 1 to different surfaces
4. Render with the new attachment
The definition of a tile being resolved is that local changes have been
flushed out to the surface, hence there is no need to reload the tile before
it's written to. For an invalid tile, the tile has to be reloaded from
the surface before rendering.
Stage (2) was marking hot tiles for attachements 0 & 1 as RESOLVED,
which means that the hot tiles can be written out to memory with no
need to read them back in (they are "clean"). They need to be marked as
resolved here, because a surface may be destroyed after a detach, and we
don't want to have un-resolved tiles that may force a readback from a
NULL (destroyed) surface. (Part of a destroy is detach all attachments first)
Stage (3), during the no att -> att transition, we need to realize that the
"new" surface tiles need to be fetched fresh from the new surface, instead
of using the resolved tiles, that belong to a stale attachment.
This is done by marking the hot tiles as invalid in stage (3), when we realize
that a new attachment is being made, so that they are re-fetched during
rendering in stage (4).
Also note that hot tiles are indexed by attachment.
