When we destroy an ARB vp/fp whose ID was gen'd but not otherwise used we
get a pointer to the dummy/placeholder program. We can't destroy that one
so just skip it. This only failed during context tear-down because
glDeleteProgramsARB() was already aware of dummy programs.

We sometimes convert GL_QUAD_STRIP prims into GL_TRIANGLE_STRIP, but
that changes the results of the u_trim_pipe_prim() call. We need to
pass the original primitive type to the trim function.

Pre-Gen6, the SF thread requires exact matching between VS output
slots (aka VUE slots) and FS input slots, even when the corresponding
VS output slot is unused due to being overwritten by point coordinate
replacement (glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE)).
As a result, we have a special hack in the VS to ensure when any
texture coordinate is subject to point coordinate replacement, it is
always allocated space in the VUE, even if it isn't written to by the
VS.
This hack isn't needed from Gen6 onwards, since SF (Gen7: SBE)
swizzling has the ability to insert the point coordinate into
gl_TexCoord[] without needing a corresponding unused VUE slot.
Note that no modification of SF setup code is required for this
patch--get_attr_override() already does the right thing. However, we
make a slight comment change to clarify why this works.
In addition to eliminating unnecessary VS recompiles and saving
precious URB space on Gen6+, this will save us the trouble of having
to adjust this hack when we implement geometry shaders.

We could potentially do some CSE even when the dst types aren't the same
on gen6 where there is no implicit dst type conversion iirc, or in the
case of uniform pull constant loads where the dst type doesn't impact
what's stored. But it's not worth worrying about.

It has become a bit messy.
Changes:
- finally correct checking for transfer ops depending on the base format
- making sure the base internal format and the texture format match
(we were ignoring it, but it's important for correctness)
- the way-too-strict rule that both src and dst base formats must be the same
was dropped; ensuring the simpler and more permissive rule mentioned above
is enough
- stop using util_blit_pixels; pipe->blit is flexible enough, and now that we
have RGBX and red-alpha formats, pipe->blit can be used for more cases

A temporary texture is created such that it matches the format and type
combination and pixels are copied to it using memcpy. Then the blit is used to
copy the temporary texture to the texture image being modified by TexImage or
TexSubImage. The blit takes care of the format and type conversion and
swizzling. The result is a very fast texture upload involving as little CPU
as possible.
This improves performance in apps which upload textures during rendering.
An example is the Wine OpenGL backend for DirectDraw, which I used to test
the game StarCraft. Profiling had shown that TexSubImage was taking 50% of
CPU time without this patch, which was the main motivation for this work, and
now TexSubImage only takes 14% of CPU time. I had to underclock my CPU to see
any difference in the game and this patch does make the game a lot faster
if the CPU is slow (or using the powersave cpufreq profile).

(tried in this order):
- memcpy-based (skips the blit) -> _mesa_tex_getimage
- blit-based
- slow pixel packing -> _mesa_tex_getimage

In GLSL, sampler indices are allocated contiguously from 0. But in the
case of ARB_fragment_program (and possibly fixed function), an app that
uses texture 0 and 2 will use sampler indices 0 and 2, so we were only
allocating space for samplers 0 and 1 and setting up sampler 0. We
would read garbage for sampler 2, resulting in flickering textures and
an angry simulator.
