configure.ac: PIXMAN_LINK_WITH_ENV fix
(fixes bug #52101)
On MirBSD, the compiler produces a (harmless) warning when the compiler
is called without the standard CFLAGS:
foo.c:0: note: someone does not honour COPTS correctly, passed 0 times
However, PIXMAN_LINK_WITH_ENV considers _any_ output on stderr as an
error, even if the exit status of the compiler is 0. Furthermore, it
resets CFLAGS and LDFLAGS at the start. On MirBSD, this will lead to a
warning in each test, making all such tests fail. In particular, the
pthread_setspecific test fails, thus pixman is compiled without thread
support. This leads to compile errors later on, or at least it did when
I tried this on pkgsrc. Re-adding the saved CFLAGS, LDFLAGS and LIBS
before the test makes it work.
The second hunk inverts the order of the pthread flag checks. On BSD
systems (this is true at least on OpenBSD and MirBSD), both -lpthread
and -pthread work but the latter is "preferred", whatever this means.

nothing uses them yet.
This commit incorporates a number of bug fixes contributed by Andrea
Canciani.
Some notes:
- The combiners are making sure to never divide by zero regardless of
input, so an application could enable divide-by-zero exceptions and
pixman wouldn't generate any.
- The operators are implemented according to the Render spec. Ie.,
- If the input pixels are between 0 and 1, then so is the output.
- The source and destination coefficients for the conjoint and
disjoint operators are clamped to [0, 1].
- The PDF operators are not described in the render spec, and the
implementation here doesn't do any clamping except in the final
conversion from floating point to destination format.
All of the above will need to be rethought if we add support for pixel
formats that can support negative and greater-than-one pixels. It is
in fact already the case in principle that convolution filters can
produce pixels with negative values, but since these go through the
broken "wide" path that narrows everything to 32 bits, these negative
values don't currently survive to the combiners.

Fix bugs in component alpha combiners for separable PDF operators
In general, the component alpha version of an operator is supposed to
do this:
- multiply source with mask in all channels
- multiply mask with source alpha in all channels
- compute the regular operator in all channels using the
mask value whenever source alpha is called for
The first two steps are usually accomplished with the function
combine_mask_ca(), but for operators where source alpha is not used,
such as SRC, ADD and OUT, the simpler function
combine_mask_value_ca(), which doesn't compute the new mask values,
can be used.
However, the PDF blend modes generally *do* make use of source alpha,
so they can't use combine_mask_value_ca() as they do now. They have to
use combine_mask_ca().
This patch fixes this in combine_multiply_ca() and the CA combiners
generated by PDF_SEPARABLE_BLEND_MODE.

Cleanups and simplifications in x86 CPU feature detection
A new function pixman_cpuid() is added that runs the cpuid instruction
and returns the results. On GCC this function uses inline assembly; on
MSVC, the function calls the __cpuid intrinsic.
There is also a new function called have_cpuid() which detects whether
cpuid is available. On x86-64 and MSVC, it simply returns TRUE; on
x86-32 bit, it checks whether the 22nd bit of eflags can be
modified. On MSVC this does have the consequence that pixman will no
longer work CPUS without cpuid (ie., older than 486 and some 486
models).
These two functions together makes it possible to write a generic
detect_cpu_features() in plain C. This function is then used in a new
have_feature() function that checks whether a specific set of feature
bits is available.
Aside from the cleanups and simplifications, the main benefit from
this patch is that pixman now can do feature detection on x86-64, so
that newer instruction sets such as SSSE3 and SSE4.1 can be used. (And
apparently the assumption that x86-64 CPUs always have MMX and SSE2 is
no longer correct: Knight's Corner is x86-64, but doesn't have them).
V2: Rename the constants in the getisax() code, as pointed out by Alan
Coopersmith. Also reinstate the result variable and initialize
features to 0.
V3: Fixes for the fact that the upper 32 bits of a 64 bit register are
zeroed whenever the corresponding 32 bit register is written to.
V4: Fixes for the fact that in 32 bit mode, when gcc is not optimizing
there were not enough registers available. The new code uses the "a",
"b", "c", and "d" constraints instead, and has two separate versions
for 32 and 64 bit modes.

whether the given feature is available.
The result is that all the pixman_have_arm_<feature> functions become
redundant and can be deleted.

Simplify MIPS CPU detection
There is no reason to have pixman_have_<feature> functions when all
they do is call pixman_have_mips_feature().
Instead rename pixman_have_mips_feature() to have_feature() and call
it directly from _pixman_mips_get_implementations(). Also on
non-Linux, just make have_feature() return FALSE.

Use a compile-time constant for the "K" constraint in the MMX detection.
When compiling with -O0, gcc doesn't understand that in
signed char x = 0;
...
asm ("...",

x is constant. Fix this by using an immediate constant instead of a
variable.

In fast_composite_tiled_repeat() don't clone images with a palette
In fast_composite_tiled_repeat() if the source image is less than a
certain constant width, a clone is created which is then
pre-repeated. However, the source image's palette, if it has one, is
not cloned, so for indexed images, the pre-repeating would crash.
Fix this by not doing any pre-repeating for images with a palette set.

test: Make stress-test more likely to actually composite something
stress-test current almost never composites anything because the clip
rectangles and transformations are such that either
_pixman_compute_composite_region32() or analyze_extent() will return
FALSE.
Fix this by:
- making log_rand() return smaller numbers so that the clip rectangles
are more likely to be within the destination image
- adding rand_x() and rand_y() functions that pick positions within an
image and using them for positioning alpha maps and source/mask
positions.
- making it less likely that clip regions are used in general
These changes make the test take longer, so speed it up a little by
making most images smaller and by reducing the maximum convolution
filter from 17x19 to 3x4.
With these changes, stress-test reveals a crash in iteration 0xd39
where fast_composite_tiled_repeat() creates an indexed image without a
palette.
