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.
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.
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.
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.
We're already using the return-value of cmp to print either PASS or
FAIL and in the case of failure, we're subsequently running and
showing the output of diff. So any warnings/errors from cmp itself are
not actually needed, and can be quite confusing.
Commit d4a04f3155 caused this test case
to produce an additional blank line, which is otherwise harmless, but
does need to be reflected in the .expected file for the test to pass.
Since we have a custom structure for YYLTYPE locations, we need to use
an %initial-action directive to avoid triggering use of uninitialized
memory when, for example, printing error messages.
We apparently don't yet have a test case that allowed valgrind to find
this bug for us, but valgrind found a similar problem in the other
parser, so we fix this one as well.

Thanks to valgrind for noticing this bug.
