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.

Simplify CPU detection on PPC.
Get rid of the initialized and have_vmx static variables in
pixman-ppc.c There is no point to them since CPU detection only
happens once per process.
On Linux, just read /proc/self/auxv instead of generating the filename
with getpid() and don't bother with the stack buffer. Instead just
read the aux entries one by one.

Simplifications to ARM CPU detection
Organize pixman-arm.c such that each operating system/compiler exports
a detect_cpu_features() function that returns a bitmask with the
various features that we are interested in. A new function
have_feature() then calls this function, caches the result, and return
whether the given feature is available.
The result is that all the pixman_have_arm_<feature> functions become
redundant and can be deleted.

- making log_rand() return smaller numbers so that the clip rectangles

- adding rand_x() and rand_y() functions that pick positions within an

- making it less likely that clip regions are used in general

calculating
c = c * 0x401UL >> 4

Add pixman_glyph_cache_t API
This new API allows entire glyph strings to be composited in one go
which reduces overhead compared to multiple calls to
pixman_image_composite32().
The pixman_glyph_cache_t is a hash table that maps two keys (a "font"
and a "glyph" key, but they are just keys; there is no distinction
between them as far as pixman is concerned) to a glyph. Glyphs in the
cache can be composited through two new entry points
pixman_glyph_cache_composite_glyphs() and
pixman_glyph_cache_composite_glyphs_no_mask().
A glyph cache may only be inserted into when it is "frozen", which is
achieved by calling pixman_glyph_cache_freeze(). When
pixman_glyph_cache_thaw() is later called, if the cache has become too
crowded, some glyphs (currently the least-recently-used) will
automatically be evicted. This means that a user must ensure that all
the required glyphs are present in the cache before compositing a
string. The intended way to use the cache is like this:
pixman_glyph_t glyphs[MAX_GLYPHS];
pixman_glyph_cache_freeze (cache);
for (i = 0; i < n_glyphs; ++i)
{
const void *g;

Pass the full image flags to iterators
When pixman_image_composite32() is called some flags are computed that
indicate various things about the composite operation that can't be
deduced from the image flags themselves. These additional flags are
not currently available to iterators. All they can do is read the
image flags in image->common.flags.
Fix that by passing the info->{src, mask, dest}_flags on to the
iterator initialization and store the flags in the iter struct as
"image_flags". At the same time rename the *iterator* flags variable
to "iter_flags" to avoid confusion.

test: Composite with solid images instead of using pixman_image_fill_*
There is a couple of places where the test suite uses the
pixman_image_fill_* functions to initialize images. These functions
can fail, and will do so if the "fast" implementation is disabled.
So to make sure the test suite passes even using
PIXMAN_DISABLE="fast", use pixman_image_composite32() with a solid
image instead of pixman_image_fill_*.
