Flushing the vertices after having already updated the state doesn't
do any good. Fixes useshaderprogram-flushverts-1. As a side effect,
by moving it to the right place we end up skipping no-op state changes
for traditional glUseProgram.
Rebuilding the vertex format from scratch every time we see a new
vertex attribute is rather costly, new attributes can be appended at
the end avoiding a copy to current and then back again, and the full
attr pointer recalculation.
In the not so likely case of an already existing attribute having its
size increased the old behavior is preserved, this could be optimized
more, not sure if it's worth it.
It's a modest improvement in FlightGear (that game punishes the VBO
module pretty hard in general, framerate goes from some 46 FPS to 50
FPS with the nouveau classic driver).

We really only want to print spaces -between- elements, not after each
element. This cleans up error messages from IR reader, making them
(mildly) easier to read.
In particular, calling the abs function is silly, since there's already
an expression opcode for that. Also, assigning to temporaries then
assigning those to the final location is rather redundant.
Trivial change that avoids a segmentation fault when the blitter state
happens to be bound when the context is destroyed.
The free calls should probably removed altogether in the future -- the
responsibility to destroy the state atoms lies with whoever created it,
and the safest thing for the pipe driver is to not touch any bound state
in its destructor.
In testing on Ironlake, the histogram of clocks/pixel results for the
system memcpy and magic unaligned memcpy show no noticeable difference
(and no statistically significant difference with the 5510 samples
taken, though the stddev is large due to what looks like the cache
effects from the different texture sizes used).
This provides the optimizer with hints about code hotness, which we're
quite certain about for debug printouts (or, rather, while we
developers often hit the checks for debug printouts, we don't care
about performance while doing so).
Discard fractional bits from linewidth. This matches the nvidia
closed drivers, my reading of the OpenGL SI and current llvmpipe
behaviour.
It looks a lot nicer & avoids ugliness where lines alternate between n
and n+1 pixels in width along their length.
Also fix up r600g to match.
These were previously being left in the default (D3D) mode. This mean
that triangles were drawn slightly incorrectly, but also because this
state is relied on by the u_blitter code, all blits were half a pixel
off.
Generalize the existing tiled_buffer path in texture transfers for use
in some non-tiled up and downloads.
Use a staging buffer, which the winsys will restrict to GTT memory.
GTT buffers have the major advantage when they are mapped, they are
cachable, which is a very nice property for downloads, usually the CPU
will want to do look at the data it downloaded.
This opens the question of what interface the winsys layer should
really have for talking about these concepts.
For now I'm using the existing gallium resource usage concept, but
there is no reason not use terms closer to what the hardware
understands - eg. the domains themselves.
The callback presents the given attachment to the native engine. It
allows the swap behavior and interval to be controlled. It will replace
native_surface::flush_frontbuffer and native_surface::swap_buffers
shortly.

This ensures that we increase bo->map_count when radeon_bo_map_internal()
returns successfully, which in turn makes sure we don't decrement
bo->map_count below zero later.
