Setting Const.MaxSamples needed a rework, so that it doesn't call
st_choose_format, which depends on st_context.
Other than that, there is no change in functionality.

The formats are emulated by translating them into plain uncompressed

This is required for GLES 3.0 and ARB_ES3_compatibility (GL 4.3).

This provides an implementation of CopyImageSubData that works if both
textures are uncompressed. This implementation works by using a
combination of texture views and BlitFramebuffer. If one of the textures
is compressed, it returns false and the driver is expected to provide a
fallback.

Previously the blorp blitter wouldn't be used if the source and destination
buffer had a different format other than swizzling between RGB and BGR and
adding or removing a dummy alpha channel. However there's no reason why the
blorp code path can't be used to do almost all format conversions so this
patch just removes the checks. However it does explicitly disable converting
to/from MESA_FORMAT_Z24_UNORM_X8_UINT because there is a similar check
brw_blorp_copytexsubimage.
This doesn't cause any Piglit test regressions at least on Ivybridge.

Different generations of hardware measure jump distances in different
units. Previously, every function that needed to set a jump target open
coded this scaling, or made a hardcoded assumption (i.e. just used 2).
Most functions start with the number of instructions to jump, and scale
up to the hardware-specific value. So, I made the function match that.
Others start with a byte offset, and divide by a constant (8) to obtain
the jump distance. This is actually 16 / 2 (the jump scale for Gen5-7).
v2: Make the helper a static inline defined in brw_eu.h, instead of
an actual function in brw_eu_emit.c (as suggested by Matt).

Now that we no longer use ctx->DrawBuffer->_Xmin and related fields to
program the screen-space viewport extents, we don't depend on any
scissoring state. So we can drop the +_NEW_SCISSOR dependency.
On GEN8, a change in scissor state does not effect anything for the
clipper/sf hardware state. The hardware will always do the right thing
once the viewport extents are programmed. We can therefore remove the
unecessary state emission.
Ken originally spotted this.
v2: Reword the commit message. Remove spurious hunk.

The goal of guardband clipping is to try to avoid 3d clipping because it
is an expensive operation. When guardband clipping is disabled, all
geometry that intersects the viewport is sent to the FF 3d clipper.
Objects which are entirely enclosed within the viewport are said to be
"trivially accepted" while those entirely outside of the viewport are,
"trivially rejected".
When guardband clipping is turned on the above behavior is changed such
that if the geometry is within the guardband, and intersects the
viewport, it skips the 3d clipper. Prior to GEN8, this was problematic
if the viewport was smaller than the screen as it could allow for
rendering to occur outside of the viewport. That could be mitigated if
the programmer specified a scissor region which was less than or equal
to the viewport - but this is not required for correctness in OpenGL. In
theory you could be clever with the guardband so as not to invoke this
problem. We do not do this, and have no data that suggests we should
bother (nor the converse data).
With viewport extents in place on GEN8, it should be safe to turn on
guardband clipping for all cases
While here, add a comment to the code which confused me thoroughly.
v2: Update grammar in commit message. Reword comments based on Ken's
suggestion.

Viewport extents are a 3rd rectangle that defines which pixels get
discarded as part of the rasterization process. The actual pixels drawn
to the screen are an intersection of the drawing rectangle, the viewport
extents, and the scissor rectangle. It permits the use of guardband
clipping in all cases (see later patch). The actual pixels drawn to the
screen are an intersection of the drawing rectangle, the viewport
extents, and the scissor rectangle.
Scissor rectangle is not super important for this discussion as it should
always help do the right thing provided the programmer uses it.
switch (viewport dimensions, drawrect dimension) {
case viewport > drawing rectangle: no effects; break;
case viewport == drawing rectangle: no effects; break;
case viewport < drawing rectangle:
Pixels (after the viewport transformation but before expensive
rastersizing and shading operations) which are outside of the
viewport are discarded.
}
I am unable to find a test case where this improves performance, but in
all my testing it doesn't hurt performance, and intuitively, it should
not ever hurt performance. It also permits us to use the guardband more
freely (see upcoming patch).
v2: Updating commit message.
