ebedd9a2ad test: Get rid of the obsolete 'prng_rand_N' and 'prng_rand_u32' 
They are the same as 'prng_rand_n' and 'prng_rand'

b31a696263 test: Switch to the new PRNG instead of old LCG 
Wallclock time for running pixman "make check" (compile time not included):

----------------------------+----------------+-----------------------------+
                            | old PRNG (LCG) |   new PRNG (Bob Jenkins)    |
       Processor type       +----------------+------------+----------------+
                            |    gcc 4.5     |  gcc 4.5   | gcc 4.7 (simd) |
----------------------------+----------------+------------+----------------+
quad Intel Core i7  @2.8GHz |    0m49.494s   |  0m43.722s |    0m37.560s   |
dual ARM Cortex-A15 @1.7GHz |     5m8.465s   |  4m37.375s |    3m45.819s   |
     IBM Cell PPU   @3.2GHz |    23m0.821s   | 20m38.316s |   16m37.513s   |

But some tests got a particularly large boost. For example benchmarking and

309e66f047 test: Search/replace 'lcg_*' -> 'prng_*' 
The 'lcg' prefix is going to be misleading if we replace
PRNG algorithm.

5f96022d3b pixman: Use uintptr_t in type casts from pointer to integral value 
These modifications fix lots of compiler warnings for systems where
sizeof(unsigned long) != sizeof(void *).
This is especially true for MinGW-w64 (64 bit Windows).

600a06c81d glyph-test: Prepare for floating point 
In preparation for an upcoming change of the wide pipe to use floating
point, comment out some formats in glyph-test that are going to be
using floating point and update the CRC32 value to match.

5b0563f39e glyph-test: Avoid setting solid images as alpha maps. 
glyph-test would sometimes set a solid image as an alpha map, which is
not allowed. When this happened and the debug spew was enabled,
messages like this one would be generated:

    *** BUG ***
    In pixman_image_set_alpha_map: The expression
            !alpha_map || alpha_map->type == BITS was false
    Set a breakpoint on '_pixman_log_error' to debug

Fix this by not passing the ALLOW_SOLID flag to create_image() when
the resulting is to be used as an alpha map.

619a60d201 test: Make glyph test pass on big endian 
The destination buffer was initialized with random uint32_t values, so
it started out different on big endian vs. little endian. Fix that by
initializing the buffer with random uint8_t values instead.

d9710442b4 test: Add glyph-test 
This test tests the new glyph cache and compositing API. Much of this
test is intending to making sure that clipping and alpha map handling
survive any optimizations that may be added to the glyph compositing.

V2: Evaluating lcg_rand_n() multiple times in an argument list lead
    to undefined behavior.
