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

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 |

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

Don't include stdint.h in scaling-helpers-test.

test: Do not include config.h unless HAVE_CONFIG_H is defined
...
The win32 build system does not generate config.h and correctly runs
the compiler without defining HAVE_CONFIG_H. Nevertheless some files
include config.h without checking for its availability, breaking the
build from a clean directory:
test\utils.h(2) : fatal error C1083: Cannot open include file:
'config.h': No such file or directory
...

test: Fix compilation on win32
...
Adding scaling-helpers-test to the testsuite on win32 makes MSVC
complain about int64_t being used as an expression:
scaling-helpers-test.c(27) : error C2275: 'int64_t' : illegal use of
this type as an expression

Rename pixman-fast-path.h to pixman-inlines.h
...
It is not really specific to pixman-fast-path.c.

test: check correctness of 'bilinear_pad_repeat_get_scanline_bounds'
...
Individual correctness check for the new bilinear scaling related
supplementary function. This test program uses a bit wider range
of input arguments, not covered by other tests.
