5266bc3c60 Revert "translate_generic: return NULL instead of assert(0) if format not supported" 
This reverts commit 16b45ca7ce.

José Fonseca asked for a revert.

Note that the testsuite will now segfault since it attempts to test
all possible formats.

684aeb366f translate_generic: fix broken A8R8G8B8_UNORM output 
translate was attempting to output A8R8G8B8_UNORM as if it were
R8G8B8A8_UNORM.

Now the tests just added pass.

945e38c73b translate: add testsuite 
Currently only checks all possible format conversions, and doesn't
attempt to test whether multiple buffers/elements or indices work.

16b45ca7ce translate_generic: return NULL instead of assert(0) if format not supported 
This gives the caller a chance to recover (or crash anyway otherwise).

deb809ec98 auxiliary: fix util_framebuffer_copy 
util_framebuffer_copy was attempting to copy all elements of the
source framebuffer state.

However, this breaks if the user does not zero initialize the structure.
Instead, only copy the elements up to nr_cbufs, and clear elements up
to dst->nr_cbufs, if the destination was larger than the source.

10ce6779e8 gallivm: Use lp_build_div instead of lp_build_mul + lp_build_rcp. 
Single divide, so let lp_build_div decide how to implement this.

This will save a multiplication in architectures which don't have
a RCP intrinsic.

b85c71d4e1 auxiliary: support for transfers using staging resources 
Direct3D 10/11 has no concept of transfers. Applications instead
create resources with a STAGING or DYNAMIC usage, copy between them
and the real resource and use Map to map the STAGING/DYNAMIC resource.

This util module allows to implement Gallium drivers as a Direct3D
driver would be implemented: transfers allocate a resource with
PIPE_USAGE_STAGING, and copy the data between it and the real resource
with resource_copy_region.

e45b2ce2c3 u_surfaces: use cso_hash instead of util_hash_table 
Using cso_hash directly is the right thing since util_hash_table
adds useless overhead and is harder to use for this application.

0dcf0f9dfa auxiliary: move Ben Skeggs' primitive splitter to common code 
This is a simple framework that handles splitting primitives in an
abstract way.

The user has to specify the primitive start, start index and count.

Then, it can ask the primitive splitter to "draw" a chunk of the
primitive, staying under a given vertex/index budget.

The primitive splitter will then call user-supplied functions to
emit a range of vertices/indices, as well as switch the edgeflag
on or off.

This is particularly useful for hardware that either has limits
on the vertex count field, or where vertices are pushed on a FIFO
or temporary buffer of limited size.

Note that unlike other splitters, it does not manipulate data in
any way, and merely asks a callback to do so, in vertex intervals.
