903c91cc2e fix for ubsan on unittest.h fastrand() 
internal math of the fastrand function uses a multiply
and add that overflows a signed int.  This triggers a
ubsan failure:

../../unit_test/../unit_test/unit_test.h:60:33: runtime error: signed integer overflow: 56248274 * 214013 cannot be represented in type 'int'

This change casts the intermediate math to unsigned
int to avoid the overflow.

For more info on ubsan, see
http://dev.chromium.org/developers/testing/undefinedbehaviorsanitizer

TESTED=Passing compilation using:
GYP_DEFINES="ubsan=1"
GYP_DEFINES="ubsan_vptr=1"

82d74a37fa unittest fix for cpu flags. 
cpu flags of 1 disables SIMD and uses C.  This used to be 0, but the change
in auto init behavior means that 0 now means uninitialized, and will cause
auto detect to reinit the cpu info.  A value of 1 disables the auto init.

c629cb3afe add command line cpu info to allow android neon test 
in order to compare C and Neon code, a new command line flag is added.
historically environment variables controlled cpu features, but on
android apk it is easier to pass a command line option to disable cpu
optimizations.

e2417df4cb create color test category of unittests to narrow down arm bug 
A hang in color conversion on arm occurs somewhere in yuv to rgb.
Breaking the color test into its own category of test will help
run selective tests to narrow down the issue.

16f12b58cc Replace random with fastrand 
random / rand is slow and impacts performance testing.
Although its only called to clear a frame once, a typical profile shows
it high in the overall profile, when doing 1000 frames for a benchmark.

Replace random is a faster version for unittests.

Allow assemblers with a slightly different syntax to use
the optimized neon routines.

Removed extra constraints on the calling of the optimized
routines.  All neon routines can load unaligned and handle
odd widths.

Align allocated buffers in rotate_test.cc
