This also allows us to split the loop emulation into two phases. A
tranformation phase which either unrolls loops or prepares them to be
emulated, and the emulation phase which unrolls remaining loops until the
instruction limit is reached. The second phase is completed after the
deadcode analysis in order to get a more accurate count of the number of
instructions in the body of loops.
These 3 fields are per shader-program. Copy them into the geometry
program at link time for convenient access later.
Also, add some missing glGetProgramiv() queries.
Before, if there were no color buffers enabled (with glDrawBuffers(GL_NONE))
when the texenv program was generated, we'd emit writes to OUTPUT[1] but
the OutputsWritten mask was 0. This inconsistency caused an assertion to
fail later in the Mesa->TGSI translation.
Fixes fd.o bug 28169
NOTE: this is a candidate for the 7.8 branch (and depends on commit
b6b9b17d27).
Need to pass the index indicating which blend terms to use, not which
color buffer we're blending into.
Rename the parameter to blend_quad() and add comments to be more clear
about this.
All the state that effects the program should be in the key.
This didn't help with bug 28169 but is a good fix anyway.
NOTE: this is a low-priority candidate for the 7.8 branch. In practice,
this issue might never be hit.
before this change, r600 glxinfo segfaulted in the list code, and I wasn't
debugging another linked list implementation, its 2010 after all.
So add the two missing list macros to the gallium header from X.org list header file (after fixing them), then port all r600 lists to the new header.

Fix this build error (in MesaGLUT-7.6.1)...
glut_cmap.c:23:66: error: X11/Xmu/StdCmap.h: No such file or directory
...by not preventing the cflags that pkg-config finds for glut dependencies
(including 'xmu') from being used.
Defining GLUT_CFLAGS before running the pkg-config prevents the
cflags found by pkg-config from being used.
This patch lets GLUT_CFLAGS that configure & pkg-config work
so hard to set actually get used.
Also make sure the generated configs/autoconf defines GLUT_CFLAGS
used in (at least) src/glut/glx/Makefile.

When compiled with the more aggressive compiler warnings such as
-Wshadow and -Wempty-body the libtess code gives a lot more
warnings. This fixes the following issues:
* The 'Swap' macro tries to combine multiple statements into one and
then consume the trailing semicolon by using if(1){/*...*/}else.
This gives warnings because the else part ends up with an empty
statement. It also seems a bit dangerous because if the semicolon
were missed then it would still be valid syntax but it would just
ignore the following statement. This patch replaces it with the more
common idiom do { /*...*/ } while(0).
* 'free' was being used as a local variable name but this shadows the
global function. This has been renamed to 'free_handle'
* TRUE and FALSE were being unconditionally defined. Although this
isn't currently a problem it seems better to guard them with #ifndef
because it's quite common for them to be defined in other headers.
